Differential Pressure Transmitter Providing High Reliability and Stability with Long Term Aging Tests for Consistent Industrial

Product Description

The general-purpose pressure transmitter utilizes a diffused silicon pressure sensor. It is composed of an isolated diffused silicon piezoresistive pressure sensing element housed within a stainless steel casing. Both the housing and connection port are made of stainless steel, and the pressure interface can be customized. It features good media compatibility and high accuracy. It is suitable for measuring various dynamic and static gases and liquids. The sensor signal is processed by a signal conditioning circuit and converted into a standard signal output. The product undergoes strict screening processes including long-term aging and stability assessments, ensuring stable and reliable performance. It can be customized for different working conditions into high-temperature resistant types, flush diaphragm types, diaphragm seal types, types with displays, etc.
