Characteristics and application scope of theory of explosion-proof pressure transmitter

Its products include explosion-proof pressure transmitter integrated intelligent sensor and peripheral circuit. Sensor part by pressure sensor, signal modulation circuit, digital processing chip, temperature sensor and data storage. Part of the peripheral circuit is liquid crystal displays, function keys and emc of circuit. Its own pressure signal by the explosion-proof pressure transmitter is converted into electrical signals, after the modem transformation into special digital processing chip so as to realize data processing, and then converted into corresponding to the pressure signal output signal between 4 to 20 ma, and special digital signal superimposed on the current signal so as to realize the function of communication. The varieties complete specifications, easy to install and use, safety explosion-proof, can be widely used in petrochemical, electric power, metallurgy, pharmacy, food processing and other industries. Product features are as follows: 1, small size, high stability, high sensitivity, the whole structure of seal welding. More than 2, type selection, ordinary users convenient debugging, safe and effective lightning protection, at the same time can prevent rf interference problem. 3, it has zero/full range freely adjustable function of choose and buy, can also choose small intelligent integrated LCD display. Two star instrument explosion-proof type pressure transmitter using the high precision, high stability of pressure sensor components, will be the absolute pressure of measured medium or gauge pressure into 4 ~ 20 ma, 0 ~ 5 VDC, 0 ~ 10 VDC, 1 ~ 5 VDC standard electrical signals, etc. Explosion-proof pressure transmitter application industry, its products are widely used in industry as follows: 1, industrial workshop pressure testing, the laboratory dedicated pressure calibration system. 2, navigation and ship manufacturing, aerospace and aircraft manufacturing. 3, air separation equipment and power units. 4, energy management system, hydraulic and pneumatic control system.

The use and installation of level gauge is compared with most other systems for managing the customized level indicator effectively and no doubt level gauge have won the race so many times.

If you cannot find the specific type of that is best for your business in the above mentioned guide, you can visit Kaidi level indicator for the best consultants specializing in this field, who can recommend the your are looking for. Customization is warmly welcomed here.

We are making level gauge available to you at a very low price.
