■ Product Overview

The EDN.351 differential pressure transmitter has all wetted parts — pressure port, sensor diaphragm, and wetted parts — made of stainless steel 316L, while the housing/body is stainless steel 304. It uses a piezoresistive silicon pressure sensor, covering pressure ranges from 0…2 bar up to 0…40 bar, with a maximum permissible static (line) pressure of 200 bar.

Using the piezoresistive effect, the input differential pressure signal is transmitted through the diaphragm and accurately converted into an analog output signal (4…20mA current or voltage output), with a fast response time of ≤5ms. Insulation resistance exceeds 100 MΩ at 100 VDC, and the sensor sealing uses an FKM O-ring for durability.

Since all wetted parts are made of stainless steel, the transmitter resists chemical corrosion except with special fluids, and a male adapter (G1/4" Male) can be added to the female pressure connection upon request.
