Product Description
The general-purpose pressure transmitter utilizes a diffused silicon pressure sensor.It consists of an isolated diffused silicon piezoresistive pressure sensing element housed in a stainless steel enclosure. Both the housing and pressure connection are made of stainless steel, and the pressure interface can be customized. It offers excellent media compatibility and high accuracy, 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 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, flush diaphragm, isolated diaphragm, or display-equipped types.
