Piezoresistive pressure sensor Honeywell Sensing and Control

Honeywell Sensing and Control's piezoresistive silicon pressure sensors contain sensing elements that consist of four piezoresistors buried in the face of a thin, chemically-etched silicon diaphragm. A pressure change causes the diaphragm to flex, inducing a stress in the diaphragm and the buried resistors. The resistor values change in proportion to the stress applied and produce an electrical output. These sensors are small, low cost and reliable. They feature excellent repeatability, high accuracy and reliability under varying environmental conditions. In addition, they feature highly consistent operating characteristics from one sensor to the next, and interchangeability without recalibration.

Best Used For:
Medical and HVAC devices, data storage and gas chromatography equipment, process controls, industrial machinery, pumps and robotics.
