Air Pressure:
Circuit uses a NPP301 pressure sensor. Range of this
sensor is1bar15psi. It will output40mV at normal air
pressure and3x overload doesnt 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 isTo 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. . . |

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,. |
