TV310 transmitter is two-wire system technical grade and micro differential pressure transmitter, adopts import micro range, high stable silicon piezoresistive sensors, and special signal processing IC. Stress isolation technology and ABS engineering plastic shell help to be packaged firmly. The differential pressure or pressure entries the positive and negative chambers through φ6 or φ8 gas mouth interfaces, signal after sensor detects is converted to corresponding 4~20mA signal of two-wire system.
TV310 technical grade micro differential pressure transmitter has many advantages such as lower rang, long-term stability, high accuracy, and simple installation/using. The gauge can be widely used in checking wind pressure in pipeline, negative pressure in chamber of furnace, heating and winding system, and other measurement of micro pressure.
