Sensors / Detectors: Pressure Detectors Circuits
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.
