WP421A 150℃ High Process Temperature HART Smart LCD Pressure Transmitter

Short Description:

WP421A 150℃ High Process Temperature HART Smart LCD Pressure Transmitter is assembled with imported heat resistant sensor element to endure high temperature process medium and heat sink construct to protect circuit board. The heat sink fins are welded on the rod between process connection and terminal box. Depending on the quantities of cooling fins, the maximum operating temperature of the transmitter can be divided into 3 classes: 150℃, 250℃ and 350℃. HART Protocol is available along with 4~20mA 2-wire analog output without additional wiring. HART Communication is also compatible with Intelligent LCD Indicator for field adjustment.
