Two Circuits Digital Vacuum Sensor Following Methode Choosed

Thermocouple Vacuum Controller ZDL-014

Thermocouple Vacuum Controller:

ZJ-14 Cold Cathode Ionization Gauge is a kind of middle-vacuum gauge suitable from 10^-1 Pa to 10^-7 Pa . There is not filament inside of the gauge, so it has longer work time and is convenient to be taken down for service . And it has the widely measuring range , better stability , etc…

Cold cathode is apt to be polluted by the oil steam in the low vacuum, which will change the surface of the cathode to make it being hard to excite the cold gauge , The followeing methode can be choosed:

a. Use the best vauum running program to shorten the retention time of the vacuum area.

b. keep work in the high vacuum .

c. stop the metal dust enters the cold gauge.

d. the appropriate installation place can help you to get away from the pollution source.

e. turn off the cold gauge if there is no work to do.

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.
