Thermocouple Vacuum Gauge vacuum meter probe vacuum sensor

ZJ-51 and M007 series long filament thermal couple (TC) is a kind of low vacuum gauge used in the earliest time at home, having the merits of simple in structure and convenient for operation. Its cover employs DM-305 glass, aluminum alloy, stainless steel, etc..

Major Technical Specifications:
1. Measuring Range: 6.65*10¹ 1.33*10^-1 Pa.
2. Filament Current: 90 - 130 mA.
3. Within the range of 13Pa1Pa, relative deviation between the standard curve and the standard characteristic curve is less than +-15%.
4. Vacuum degree within the glass gauge is not less than 5*10^-2 Pa before unsealing.

Cautions for Operation:
1. Calibrate the heating current before unsealing.
2. The labeled heating current of the metal gauge can be used as reference for operation.
3. Better install the gauge vertically.

ZJ-53 and ZJ-54 (M713, M714) series short filament thermal couple gauge have the advantages of rapid response, anti-oxidation and stable performance, etc. Its cover adopts DM-305 glass, aluminum alloy, stainless steel, porcelain, etc.

Major Technical Specifications:
1. Measuring Range: 3*10²1*10^-1 Pa.
2. Heating Current: 27.5+-1.5 mA
3. Response Time: < 3s
4. Within the range of 150Pa, relative deviation between the calibration curve and the standard characteristic curve is less than +-15%.
5. Vacuum degree within the glass gauge is not less than 5*10^-2 Pa before unsealing.

Cautions for Operation:
1. Measuring heating current value before unsealing.
2. The labeled heating current of the metal gauge can be referenced for operation.
3. Better use the gauge under vertical installation;

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.
