Sensors / Detectors: Pressure Detectors

Air Pressure: Circuit uses a NPP301 pressure sensor. Range of this sensor is1bar15psi. It will output40mV at normal air pressure and3x overload doesn't damage the device.


Circuit adds programmability to sensor amplifier: 03/21/2002  EDN - Design Ideas / The pressure-sensor amplifier circuit of Figure 1 offers a number of advantages over the traditional approach using the classic three-op-amp instrumentation amplifier. The circuit can operate from a single supply and uses only two op amps and 1% resistors. If the reference voltage, VREF, is 0V, the transducer gain for the circuit is to ensure equal gain for the two ground-referenced volt... .
