Chinese wholesale Rs485 Pressure Transmitter - WP421B 350℃ Medium and high Temperature Pressure Transmitter – Wangyuan Detail:

WP421B 350℃ medium and high temperature pressure transmitter is widely used to measure and control for various industries, including hydraulic and level measurement, Boiler, Gas tank pressure monitoring, Industrial test and control, Petroleum, Chemical industry, offshore, electric power, ocean, coal mine and Oil & Gas.

The WP421B medium and high temperature pressure transmitter is assembled with imported high temperature resistant sensitive components, and the sensor probe can work stably for a long time at a high temperature of 350℃. The laser cold welding process is used between the core and the stainless steel shell to completely melt it into one body, ensuring the safety of the transmitter under high temperature conditions. The pressure core of the sensor and the amplifier circuit are insulated with PTFE gaskets, and a heat sink is added. The internal lead holes are filled with high-efficiency thermal insulation material aluminum silicate, which effectively prevents heat conduction and ensures the amplification and conversion circuit part work at allowable temperature.
