WP401A High Precision Flame-proof HART Pressure Transmitter

Short Description:

WP401A High Precision Flame-proof HART Pressure Transmitter is a standard structure analog outputting pressure measuring device. Upper aluminum shell junction box is composed of amplifying circuit board and terminal block for conduit connection. Advanced pressure-sensing chips is sealed inside the lower wetted part. Excellent solid-state integration and membrane isolation technology make it a rather favourable option for a full range of industrial automation control system.
