100 PSI Pressure Sensor

The AMP EFI LDM-0100PSI-wPiggy is a versatile pressure sensor engineered for precise measurement of fuel, oil, or boost pressures, handling ranges from 0 to 100 PSI. It provides a consistent and linear 0-5V output signal, ensuring seamless integration with various aftermarket engine management systems, such as MegaSquirt and MS3Pro. Installation is straightforward thanks to its 1/8” NPT screw-in thread size. This sensor boasts high accuracy, rated at ±1% of full scale, and is built to withstand demanding conditions with a robust construction suitable for working temperatures between -40°F and 257°F (-40°C to 125°C). The sensor's output values can be configured based on firmware version. For Firmware 1.6, selecting the “Linear 0.5v-4.5v” option maps 0.5V to 0 PSI and 4.5V to 100 PSI. For Firmware 1.5 or older, the “Linear” option provides a 0.0V to 5.0V output range, corresponding to -12.5 PSI to 112.5 PSI. When using the sensor for dome pressure measurements with the 0-100 PSI version, the “Linear” setting must be selected, and the pressure sensor must be scaled in KPA, with 0V equating to 13.81 kPa and 5V to 875.69 kPa. Wiring is clearly defined: Red connects to 5V Vref, Black to Sensor Ground, and Yellow provides the Signal Output to the ECU. The package includes the 0-100 PSI Pressure Sensor, with an optional 15ft cable featuring a 90° boot available.
