Microprocessor Digital Vacuum Controller Compound Vacuum Gauge

Thermocouple Vacuum Controller ZDF-5227-II

Thermocouple Vacuum Controller:

ZDF-5227 compound vacuum gauge, which is composed by resistance meter and ionization meter, can test signs of the vacuum gauge with two circuits and has two circuits control contact output. In the testing range, it can be point control and area control freely, and it is suitable to be used in testing and controlling the vacuum of wide measuring range.

It adopts the most advanced microprocessor as its main machine, improving its reliability by decreasing external components. 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.

Parameter

Founded in 1958, Guoguang Electric Co., Ltd. Chengdu. is one of the Soviet Union's aids 156 key projects during the 1^st Five-Year plan, and also a comprehensive factory dedicated in manufacturing of microwave electron. In October of 2000, the factory is reorganized into a share-holding corporation that set foot in science research, manufacturing and trading. The headquarter and the manufacturing base are situated in the state-level economic and technological development zone of Longquanyi District, Chengdu city. The manufacturing base area is 133,340m² and the total area of structure is 80,000m². The total asset of the company is nearly 900 million RMB and net asset is 600 million RMB. Over 1100 staff members have been employed and over 30% of them are medium and high ranking technicians.

The main business scope of the company is: Research and production for all kinds of microwave electron vacuum parts, solid microwave devices and microwave encapsulation, vacuum contactor and breaker, vacuum chamber, switch gear, aircraft kitchen appliance(including train meal-trolley) , exhaust carts, all kinds of non-standard machinery and electrical equipment, vacuum gauge, vacuum measurement instruments, appliance of microwave energy, microwave source, medical laser appliances, etc. The products have been sold as far as overseas market and achieved great contributions for the national defense and scientific research work.

The company has been attaching much importance to the development of technology and equipment renewal since its establishment. To guarantee the production, the company has introduced much advanced equipment from U.S., France, Austria, Italy, Germany, etc. Our company has a complete internal matching capacity, besides the developing and researching of components, devices and overall unit, we can do raw material analysis, precision component processing, ceramic manufacturing and sealing, cathode manufacturing, surface treating, reliability and environment test.
