Product Overview
Chinese pressure transmitters are widely used industrial instruments for measuring gauge, absolute, and differential pressure in various processes. They typically use piezoresistive sensing technology and provide a stable 4-20 mA output. These transmitters are known for their simple structure, reasonable accuracy, and competitive price, making them a popular choice for general monitoring and control in Chinese factories and export markets.
