>product overview

WIDEPLUS-CTThe pressure transmission controller is a multifunctional product that integrates pressure measurement, display, control, and microcomputer communication. This product is a fully electronic structure, with a pressure sensor with an oil filled core with an isolation film at the front end. The output signal is sent to the microprocessor by a high-precision, low-temperature drift, and high reliability amplification circuit and analog-to-digital conversion circuit. After calculation, the high-precision analog-to-digital conversion circuit converts the data into a standard signal output. Equipped with five independent relay contact outputs, it can directly replace the electric contact pressure gauge. It is flexible to use, easy to operate, and easy to adjust. It is widely used in various industries such as power, tap water, water treatment, petroleum, chemical, and metallurgy to measure, display, control, and remotely transmit the pressure of fluid media. It is an intelligent digital pressure measuring instrument.
