Brief Introduction
1.1 The apparatus
ZDZ-52 resistance vacuum gauge controller can test one channel signal of the gauge tube; controlling two channels contact output of the relay and having the 0-5V analog output. In the testing range, it can be set freely for the point control and the area control, and it is suitable to be used in testing and controlling the rough and low vacuum.
It adopts the top quality microprocessor as its main machine, improving its reliability by decreasing external components. Its power supply employs high quality module supply; Its hardware employs the modular structure, EMI restraint and WATCHDOG circuit; while the software employs anti-interference technique, such as redundancy, trap, digital filtering and so on to improve its anti-interference ability and performance, which ensures the high reliability of the apparatus and its normal use in bad industrial environment.
