Calibration and use of a rugged new piezoresistive pressure transducer

PDF Version Also Available for Download.

Description

A new 50-ohm piezoresistive pressure gauge has been developed and calibrated in the range 0 to 4.0 GPa. This ``pinducer`` consists of one half of 100 ohm, one quarter watt, carbon composition resistor mounted coaxially at the end of a small brass tube. Three techniques have been used to calibrate this new gauge. Good agreement is found between all calibration data, and a smooth curve is fit through all resistance change versus pressure data up to 1.5 GPa. The gauges exhibit rise times of about 0.5 {mu}s. They offer advantages in raggedness, cost, and flexibility of application. The pinducer can ... continued below

They offer advantages in raggedness, cost, and flexibility of application. The pinducer can be successfully used in divergent flows, harsh environments, and positions where lead protection would be impossible with thin-film gauges. A unique application is demonstrated.
