Specifications

Measurement Method
The transmitter is with a small profile, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing. The package utilizes silicon oil to transfer pressure from 316L stainless steel diaphragm to the sensing element. A ceramic substrate is attached to the package that contains laser-trimmed resistors for temperature compensation and offset correction.

Installation
Submersible
