Product Description

The PM02X series fully welded pressure transmitter is a high-precision, high-stability pressure measurement product independently designed and manufactured by our company. Structurally, it adopts full welding sealing with no internal O-rings. Combined with a dedicated digital circuit, it undergoes signal processing such as signal amplification, linear compensation, anti-interference, and surge protection to output industrial standard signals, serving as a fully welded pressure measurement product.

Product Application

◆Petroleum chemical industry
◆Constant pressure water supply
◆Measurement and control technology
◆Hydraulic and pneumatic fields
