Product Description

The PM04X series high-temperature pressure transmitter adopts a diffused silicon oil-filled core as the pressure measuring element. The process connection is equipped with a built-in heat sink for cooling or uses a high-temperature sapphire sensor. The whole device is combined with a dedicated digital circuit, and after signal processing such as signal amplification, linear and temperature compensation, anti-interference, and surge protection, it outputs industrial standard signals, serving as an integrated product for high-temperature environment applications. Additional external heat sinks can be used for pressure measurement in higher-temperature environments.

Product Application

◆Petroleum chemical industry;

◆Metallurgy and electric power industry;

◆High-temperature liquids and gases;

◆Measurement and control technology;
