Introduction of silicon pressure sensor:
The core of the HT26 silicon piezoresistive pressure sensor is a highly stable diffused silicon element. It is a small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing. The HT26 compensated is offered in a weldable package or with avariety of threaded fittings such as 1/4 and 1/8NPT, 1/4BSP as well as custom process fittings.
