1.Description
Water pressure controller QYK104J is pressure measurement & control product with intelligent digital display, it is combined the functions of pressure measurement, display, output and control. This product is made with entire electronic structure, and built isolated-membrane pressure sensor in its front end. Its output signal is amplified through high accuracy & low temperature swift amplifier, then is input high accuracy A/D converter, and processed by microprocessor, the processed signal controls two-way switch, to realize the pressure measurement and control for systems.
The use is very flexible. QYK104J 's operation and adjustment is simple and easy, meanwhile, this product also has good reliability and safety.
