WP421B 150℃ All Stainless Steel Tiny Size Cable Lead Pressure Transmitter

Short Description:

WP421B 150℃ All Stainless Steel Tiny Size Cable Lead Pressure Transmitter is composed of advanced thermal resistant sensing mechanism to withstand high temperature process medium and construct of cooling fins to protect upper circuit board. The sensor probe is able to work for long periods of time stably at 150℃ high medium temperature. The internal lead orifices are filled with high-efficiency thermal insulation material aluminium silicate, which effectively prevents heat conduction and ensures the amplification and conversion circuit board run at acceptable temperature span. The tiny pressure transmitter adopts compact all stainless steel cylindrical case and cable lead electrical connection making its ingress protection reaches IP68.
