The answer is as follows: The following is the instruction manual of XMTD digital display regulator:
I. Overview
XMTD series digital display regulator is a new generation of intelligent controlled instrument produced by our company. It adopts advanced micro-processing technology and large-scale integrated circuit. It has the characteristics of high precision, strong reliability, easy operation and complete functions. Widely used in electric power, chemical industry, metallurgy, textile, food, medicine and other industries of temperature, pressure, flow, liquid level and other controlled parameters of automatic regulation.
Second, structure and principle
XMTD regulator includes instrument body and sensor two parts, the sensor is responsible for converting the controlled parameters into standard electrical signals, into the instrument body, after amplification, filtering, AD conversion, digital signal processing and other procedures, and finally displayed on the digital tube, and through the control output outlet output standard electrical signals, drive the actuator to realize the automatic adjustment of the controlled parameters.
