■ Product Overview

The EDN.355 differential pressure transmitter is manufactured with all joints joined by laser welding, and all wetted parts are made of stainless steel.

The pressure sensor is a piezoresistive silicon sensor, with a minimum differential pressure measurement range of 400 mbar or higher, and a maximum static (line) pressure of up to 200 bar.

This product measures differential pressure using two piezoresistive sensors. Silicone oil is filled between the dies, transmitting pressure applied to the two diaphragms to the amplifier.

Electrical wiring forms the circuit, and semiconductor-based chips are used for signal processing.

Through the piezoresistive effect, the input pressure signal forms a linear relationship with the Wheatstone bridge on the die, allowing accurate differential pressure measurement and analog signal output.

Since all wetted parts are made of stainless steel, chemical corrosion does not occur except for special fluids.

Additionally, depending on application requirements, a male adapter can be added to the female pressure connection.
