    WP421A Medium and high Temperature Pressure Transmitter

    The WP421medium 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.
