   YY18 ceramic piezoresistive pressure sensor
 
Description
YY18 temperature compensated ceramic piezoresistive pressure sensor is an ideal pressure sensing element, it can be used to mount metal housing or directly integrated with electronic circuits machinery and equipment integration.

Full temperature compensated to ensure that within the operating temperature range, the maximum temperature drift of no more than ± 0.03% FS / ℃. This structure makes the sensor remained very stable in harsh conditions . Internal sensing elements are fully protected against humidity, moisture and chemical corrosion. Fear condensation, providing a typical output 3mV / V, allows simple signal conditioning..
