FX2Q121 Pressure Sensor

Available from stock
weFlux2 pressure sensors measure the relative pressure of any desired media in closed systems. The pressure acting upon the sensor is converted to an electronic signal. The analog outputs read out the measured pressure and temperature values as 4 to 20 mA signals.
