SN3351 intelligent remote transmission pressure/differential pressure transmitter

overview

The SN3351 intelligent remote transmission pressure/liquid level transmitter is based on the 3051 core, with a sealed remote transmission device added to avoid direct contact between the measured medium and the sensor diaphragm of the transmitter, thereby isolating the corrosiveness and temperature conduction of the medium and improving the application range of the transmitter. It has all the characteristics of SN3051 and can measure high temperature, corrosive, viscous, and easily crystallizable media.

characteristic
