■ Product Overview

The EDN.713 series is a hygienic pressure transmitter designed for applications in food, beverage, pharmaceutical, and medical industries where cleanliness and hygiene are critical.

 

All components are made of stainless steel, ensuring durability and preventing issues such as coating peeling or particle contamination found in painted instruments.

 

It utilizes a piezoresistive silicon pressure sensor combined with advanced electronics and PCB design, providing high accuracy and reliability.

 

The internal circuitry incorporates protection against noise, burst, insulation, and surge, ensuring stable operation in industrial environments.

 

Optional RS485 communication and dual relay outputs allow easy integration into various control systems.

 

■ Pressure Measurement Principle

The EDN.713 measures pressure using a piezoresistive silicon pressure sensor.

 

Pressure is transmitted through a stainless steel diaphragm, generating a small deformation that is converted into an electrical signal.

 

This signal is amplified and compensated to provide stable analog or digital output.

 

■ Materials of Wetted Parts

All wetted parts and housing are made of stainless steel, ensuring excellent corrosion resistance and cleanability.

 

Various sanitary process connection standards are supported:

▶ ASME & ISO 1127

▶ DIN 11851

▶ APV-RJT

▶ IDF

▶ Flush extension mounting

 

■ Accuracy Class
