27 & 37 mV Output Pressure Sensor
Brand: American Sensor Technologies IncThe 27 and 37 mV UltraStable™ are high performance, temperature compensated, piezoresistive silicon pressure sensors packaged in a TO-8 configurations.
Gauge and differential pressure ranges from 0 to 15 to 0 to 250 psi are available. Integral temperature compensation is provided over a range of -20 to +85º C using laser-trimmed resistors.
An additional laser-trimmed resistor is included to normalize pressure sensitivity variations by programming the gain of an external differential amplifier. This provides sensitivity interchangeability of ±1%.
