WIDEPLUS-CT series pressure transmitter controller

>Product Overview

WIDEPLUS-CT pressure transmitter controller is a multifunctional product integrating pressure measurement, display, control, and microcomputer communication. The product is a fully electronic structure. The front end adopts a pressure sensor with an isolation film and an oil-filled core. The output signal is sent to the microprocessor by a high-precision, low-temperature drift and high-reliability amplifier circuit and analog-to-digital conversion circuit. Converted to standard signal output by high-precision digital-to-analog conversion circuit. With five independent relay contact outputs, it can directly replace the electric contact pressure gauge. It is flexible to use, simple to operate and easy to adjust. It is widely used in power, tap water, water treatment, petroleum, chemical, metallurgical and other industries. It is a kind of intelligence to measure, display, control and remotely transmit the pressure of fluid media. Digital pressure measuring instrument.
