WP435C Sanitary Type Flush Diaphragm Non-cavity Pressure Transmitter

Short Description:

WP435C Sanitary Type Flush Diaphragm Non-cavity Pressure Transmitter is specially designed for food application. Its pressure-sensitive diaphragm is at the front end of the thread, the sensor is at the back of the heat sink, and high-stability edible silicone oil is used as the pressure transmission medium in the middle. This ensures the effect of low temperature during food fermentation and high temperature during tank cleaning on the transmitter. Operating temperature of this model is up to 150℃. Transmitters for gauge pressure measurement use vent cable and put molecular sieve on both ends of the cable that avoiding the performance of transmitter affected by condensation and dewfall. This series are suitable to measure and control the pressure in all kinds of easy to clog, sanitary, sterile, easy to clean environment. With the feature of high working frequency, they also are fit for dynamic measurement.
