■ Product Overview

The EDN.620 series is a pressure transmitter designed with a flush diaphragm structure, making it suitable for viscous media and hygienic applications.

 

All wetted parts and housing are made of stainless steel, ensuring excellent corrosion resistance and durability, as well as suitability for food, pharmaceutical, and other hygienic environments.

 

The standard process connection is G1/2”, and various sealing options such as FKM, EPDM, and metal O-ring are available.

 

It utilizes a piezoresistive silicon pressure sensor combined with advanced electronics and PCB design to ensure high accuracy and stability. The internal circuitry includes protection against noise, burst, insulation, and surge, enabling reliable operation in various industrial environments.

 

All units are fully calibrated under strict quality control processes to ensure long-term reliability.

 

■ Pressure Measurement Principle

The EDN.620 measures pressure using a piezoresistive silicon pressure sensor.

 

The flush diaphragm allows direct pressure transmission even in viscous or contaminated media, preventing clogging and ensuring stable measurement.

 

Pressure-induced deformation is converted into an electrical signal and processed by internal electronics to provide a stable output.
