PRESSUREPressure Sensor forDirect Liquid DetectionADPW11 direct liquiddetection pressure sensorPanasonic’s custom designed sensor chip detects liquid pressure directly inaddition to air pressure. Linear output for positive and negative pressure.Product OverviewThe PS-A pressure sensor lineup offers the advantage of abuilt-in amplifier and compensating circuit in model ADPW11.Based on a MEMS sensor chip design, the sensor measurespressure with a piezoresistive element and provides a voltageoutput. Various liquid mediums are measurement compatible,including water, chemical solutions, oil, and gas (e.g. highhumidity air). Standalone design offers simplicity in mountingthe sensor without requiring a PCB (see Figure 1).Features & BenefitsDirect liquid detection•§Design simplicity with direct attachment to installation holeBuilt-in amplifier and compensating circuit•§Compact size and easy integrationSensor and IC chip protected by potting•§Resistant to high temperature and high humidity conditionsLinear output for both positive and negative pressure•§Measurement accuracy from -19.6kPa to 49.0kPaLow power consumption (16mW typ.)•§Energy savingsStandalone design with connector•§No soldering on boardADPW11 offers direct liquid detection in the PS-A pressuresensor lineup (see Figure 2). Pressure sensor moduleincludes only a sensor and IC chip, providing increasedresistance against ambient conditions. Measures gaugepressure and withstands maximum applied pressure of -90to 350kPa.ApplicationsWater level detection (e.g. water heater, storage tank) andindustrial water pressure monitoring in piping. Compatiblewith other applications requiring direct pressure detection ofliquid medium.Fig.1 ADPW11 standalone design mountingFig.2 ADPW11 ordering informationADPW 1 1PS-A Direct water pressure detection typeShape1: Standalone typeInstallation hole 4.5mm dia., 40mm pitchPipe shape: 6mm dia., No 0-ring grooveCompatible plug: XMP-04VRated pressure1: Negative pressure - 19.6kPaPositive pressure 49.0kPa*Please inquire about pressure rangePRESSURE83www.FutureElectronics.com/Sensors
