The Appication of Temperature Transmitter:

The technology index&structure characteristics ect. of LDWB double wire system, triple wire system temperature transmitter are ranking at national leading level, and also reaching the same products level abroad in late 1990s. It brings great convenience for many people with occupation of automatic control &design and other users.

Explosion-separation type mechanical-electical integration temperature transmitter is designed and developed by our company. This product absorbs advantages of the same products according to the national standard & special standard newly promulgated. It features as novelty structure, safely reliable, convenient for users and observing the temperature change on spot. Design&manufacture , hydroelectric performance and explosion-separation are all in line with international IEC standard. This product is qualification which is tested by national instrument& meter explosion-proof safety surveillance inspection bureau.

It is widely used in petroleum,natural gas, chemical industry, metallurgy,hydroelectric, cement,glass industried etc. it is connected with various electronic meter, intelligent digital-display meter and computer control system etc.
