Product Description

Overview
QYB203 is composed of stainless steel air collector, stainless steel capillary tube and terminal box. When air collector is put into measured liquid, the air in the collector would be compressed, therefore the changing air pressure would be transmitted through the capillary tube to the sensor. This type of transmitter is made to avoid the direct contact between sensor and measured medium, such as high temperature, corrosive liquid, been widely used in environmental industry, hydraulic, chemical engineering, sewage etc.
