Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious personal injury. • SAVE THESE INSTRUCTIONS • WORK AREA • Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents. • Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes. • Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control. • ELECTRICAL SAFETY • Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adaptor plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user. Applicable only to Class I (grounded) tools. • Double insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double insulation eliminates 1 the need for the three wire grounded power cord and grounded power supply system. Applicable only to Class II (double insulated) tools. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded. Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W.” These cords are rated for outdoor use and reduce the risk of electric shock. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

Datasheet SHT1x (SHT10, SHT11, SHT15) Humidity and Temperature Sensor: Fully calibrated Digital output Low power consumption Excellent long term stability SMD type package – reflow solderable Product Summary Each SHT1x is individually calibrated in a precision humidity chamber. The calibration coefficients are programmed into an OTP memory on the chip. These coefficients are used to internally calibrate the signals from the sensors. The 2-wire serial interface and internal voltage regulation allows for easy and fast system integration. The tiny size and low power consumption makes SHT1x the ultimate choice for even the most demanding applications. Dimensions Sensor Chip 1.5 ±0.2 2.0 ±0.1 1.5 ±0.1 sensor opening 1 2.5 ±0.1 NC 4 A5Z 11 Material Contents NC NC 2.2 MAX 2 5.2 ±0.2 4.2 ±0.1 1.27 ±0.05 NC 3 1.83 ±0.05 7.47 ±0.05 NC SHT1x is supplied in a surface-mountable LCC (Leadless Chip Carrier) which is approved for standard reflow soldering processes. The same sensor is also available with pins (SHT7x) or on flex print (SHTA1). SHT1x V4 – for which this datasheet applies – features a version 4 Silicon sensor chip. Besides a humidity and a temperature sensor the chip contains an amplifier, A/D converter, OTP memory and a digital interface. V4 sensors can be identified by the alpha-numeric traceability code on the sensor cap – see example “A5Z” code on Figure 1. 0.6 ±0.1 0.95 ±0.1 SHT1x (including SHT10, SHT11 and SHT15) is Sensirion’s family of surface mountable relative humidity and temperature sensors. The sensors integrate sensor elements plus signal processing on a tiny foot print and provide a fully calibrated digital output. A unique capacitive sensor element is used for measuring relative humidity while temperature is measured by a band-gap sensor. The applied CMOSens® technology guarantees excellent reliability and long term stability. Both sensors are seamlessly coupled to a 14bit analog to digital converter and a serial interface circuit. This results in superior signal quality, a fast response time and insensitivity to external disturbances (EMC).

One of the more commonly misunderstood aspects of Electronic Fuel Injection (EFI) is how to select the correct size fuel injectors, fuel pump and Mass Air Flow (MAF) sensor for a particular engine horsepower output. The following information is intended to offer a very brief tutorial on properly selecting the most common EFI components. FUEL INJECTORS First and foremost, adding larger fuel injectors alone will NOT create extra horsepower! The purchase of larger fuel injectors should only be considered when your engine has exceeded the horsepower capacity of the existing fuel injectors, at which point larger injectors are then required to SUPPORT the additional horsepower. If you add largerthan-stock injectors to an otherwise stock engine, you should not expect any horsepower increase whatsoever. The nominal injection pressure for most Ford EFI systems is 39.15psi (270kPa) “across the injector.” The term “across the injector” takes manifold pressure and fuel rail pressure into account, and is usually referred to as “delta pressure.” (See “Measuring Fuel Pressure” below for more details.) Ford Racing’s fuel injectors are always rated at 39.15psi delta, so the fuel injector sizing discussions found below will assume a fuel pressure of at least 39.15psi delta. There are some exceptions to the above-mentioned nominal injection pressure. In relatively recent years, emissions regulations have become so stringent that the government is now regulating the emissions output that gasoline vehicles are allowed to produce even when the engine is not running! This is referred to as “evaporative emissions” and results from unburned hydrocarbons (raw fuel) emitting into the atmosphere from the fuel tank, fuel lines, injector leakage, intake manifold, etc. when the engine is shut off. This is the fundamental purpose of the charcoal canister (and hydrocarbon trap in the air-box on many vehicles) and is also the reason that Ford switched to the Returnless Fuel Systems (RFS) found in production vehicles today. These systems have only a fuel supply line from the tank to the engine, with no return line. The primary reason for these systems is that evaporative emissions increase as the temperature of the fuel in the tank increases. On a conventional return system, the fuel is sent to the engine through the supply line, and the excess is returned (via the mechanical fuel pressure regulator) to the tank through the return line. Since the engine is hot, this process heats up the fuel and thus increases evaporative emissions. To combat this, the returnless fuel systems were invented. Currently, Ford uses 2 primary types of RFS which are called Electronic Returnless Fuel System (ERFS) and Mechanical Returnless Fuel System (MRFS). The latter is the simpler of the two systems and controls the fuel rail to a constant pressure via a regulator in the tank, which is typically set to around 60psi. The Powertrain ...
The National Instruments 9758 Port Fuel Injector (PFI) Driver Module includes a CompactRIO (cRIO) module for driving low and high impedance Port Fuel Injectors (PFI) and general purpose automotive solenoid valves and actuators. The NI 9758 includes a LabVIEW FPGA VI for controlling each driver channel. Each PFI channel is individually controlled for timing and duration. Each general purpose low-side solenoid driver is PWM controlled, capable of 0% to 100% duty cycle operation. Features: • 4-channel low or high impedance PFI driver – Turnable current level and duration for each phase – Optional recirculation at end of pulse – • Two phase current control – Open and short circuit detection and reporting with short circuit disable 4-channel general purpose low-side solenoid driver – 1.5 A continuous duty – PWM controlled • • – 2 Hz to 10 kHz frequency operation • • 0% to 100% duty cycle operation 500 ns resolution Open and short circuit detection and reporting with short circuit disable External power supply of 7 V to 32 V Pinout Figure 1. NI 9758 Pin Assignments 2 | ni.com | NI 9758 User Manual Hardware The NI 9758 provides four port fuel injector drivers and four general purpose low-side solenoid drivers in a NI CompactRIO module. Powering the Module The NI 9758 requires power from two different sources, a 15-pin D-SUB (HD15) connector and the external screw-terminal connector. The CompactRIO backplane male high density D-SUB 15-pin (HD15) connector mates with the module’s female HD15 connector. This power source provides a regulated 5 V and ground to various digital logic functions within the module. The CompactRIO 5 V source is active whenever the CompactRIO or R Series Expansion Chassis is properly powered. The NI 9758 should only be powered at the HD15 connector by plugging it into a CompactRIO or R Series Expansion Chassis. The NI9758 HD15 connector should not be connected to any other device. The external screw-terminal connector with the terminals labeled BATT (0) and GND (9) provide a second power source. Typical power sources will be from automotive 12 V or 24 V battery systems. The NI 9758 can accept power from 7 V to 32 V. The NI 9758 requires a maximum of 100 mA from an external power supply. When actuators and injectors are connected to and powered from the same power supply as the NI 9758, a battery or power supply capable of 10 A continuous output will be required under a full load. The NI 9758 requires both external power and power from the CompactRIO backplane. The high current path is directed through the BATT and GND terminals on the front of the NI 9758, not through the HD15 backplane connector. Note ...

Reading and understanding centrifugal pump curves is key to proper pump selection, and to their reliable and efficient operation. This Tech Brief examines how pump curves can provide data about a pump’s ability to produce flow against certain head, shows how to read a typical centrifugal pump curve, and provides information about pump efficiency and brake horsepower. Pumps are the workhorses of any drinking water distribution or wastewater collection system. They operate 24 hours a day, 365 days a year getting water to homes and business, and removing wastewater from them. A correctly sized pump will work efficiently for many years, saving a system money and energy. An incorrectly sized pump can fail if it’s too small or result in unnecessary expense if it’s too big. Pump curves provide a way to see the correct size a pump should be for specific conditions. Pump Terminology Before discussing specific details, it helps to understand typical terms associated with pump curves: Impeller—the moving element in a pump that drives the liquid. Volute—the spiral-shaped casing surrounding a pump impeller that collects the liquid discharged by the impeller. Head—a measure of the pressure or force exerted by water expressed in feet. Centrifugal pump curves show pressure as head, which is the equivalent height of water with specific gravity = 1. Static Head—the vertical height difference from the surface of a water source to the centerline of the impeller. The vertical height difference from the centerline of the impeller to the discharge point is called discharge static head, while the vertical height difference from the surface of the water source to the discharge point is known as total static head. Total Head / Total Dynamic Head—the total height difference (total static head) plus friction losses and demand pressure from nozzles etc. (total discharge head) = total dynamic head. Capacity/Flow—the rate of liquid flow that can be carried, typically measured in gallons per minute (gpm). Net Positive Suction Head—how much suction lift a pump can achieve by creating a partial vacuum. Atmospheric pressure then pushes liquid into pump. A method of calculating if the pump will work or not. Cavitation—cavities or voids in liquid. Bubbles take up space leading to a drop in pump capacity. Collapsing bubbles can damage the impeller and volute, making cavitation a problem for both the pump and the mechanical seal. Specific Gravity—the weight of liquid in comparison to water at approximately 20° C (SG = 1). Specific Speed—a measure of the function of pump flow, head, and efficiency. Vapor Pressure—the force exerted by the gas released by a liquid in a closed space. If the vapor pressure of a liquid is greater than the surrounding air pressure, the liquid will boil. Viscosity—a measure of a liquid’s resistance to flow (i.e., how thick it is). The viscosity determines the type of pump used, how fast it can run, and with gear pumps, the internal clearances required. Friction Loss—the amount of pressure / head required to force liquid through pipes and fittings.
