■ Product Overview
The
EDN.830 series is a precision-engineered pressure transmitter housed in a
durable aluminum body with a bright, high-visibility LCD display, designed for
stable operation in a wide range of industrial environments.
The
sensor is a piezoresistive silicon element with a gold-plated stainless steel
diaphragm, developed specifically for hydrogen pressure measurement.
Wetted
parts are made of stainless steel 316L with a gold-plated diaphragm, preventing
hydrogen embrittlement and ensuring long-term stability and durability.
The
signal amplification electronics are designed with advanced protection against
noise, burst, insulation, and surge, ensuring stable analog and communication
output signals.
The
EDN.830 supports RS485 digital communication and 2-channel relay (switch)
functions, allowing flexible configuration according to user requirements.
The
product has undergone rigorous comparative testing and EMC/EMI testing,
ensuring reliable performance even under harsh industrial conditions such as
high temperature, electrical noise, and surge environments.
