Electronic Pressure Detector & Sensors 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.

Altimeter:

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.

Fluid solution for water-tank pressure sensing: 06/09/97 Electronic Design - Ideas for Design / Liquid sensors require a media-compatible, solid-state pressure sensor. The pressure range of the sensor depends on the height of the column or tank of fluid that must be sensed. Described here is a way to sense water height in a tank or column using.

Pressure Gauge Responds Linearly to Altitude: 03/03/94 EDN-Design Ideas

Use Accelerometers For Vibration Measurement And Control: 01/10/00 Electronic Design - Ideas for Design / Recent advances in microelectronic mechanical systems (MEMS) have made high-performance, high-accuracy, low-cost accelerometers available on a single monolithic IC. Accelerometers are used for acceleration and tilt measurements, vibration control.
