Introduction to the characteristics of explosion-proof pressure transmitter products and practical application

by:KAIDI     2021-01-18
Explosion-proof type pressure transmitter consists of integrated intelligent sensor and peripheral circuit. Sensor part by pressure sensor, signal modulation circuit, special digital processing chip, temperature sensor and data storage and so on, peripheral circuit part consists of LCD display, function keys and EMC circuit. Pressure by the pressure sensor signal into electrical signal, the signal after modulation digital processing chip dedicated to data processing, then converted into pressure signals corresponding to 4 ~ 20 ma output signal, and HART digital signal superimposed on the current signal to communicate. Explosion-proof pressure transmitter consists of integrated intelligent sensor and peripheral circuit. Sensor part by pressure sensor, signal modulation circuit, special digital processing chip, temperature sensor and data storage and so on a variety specification is complete, easy installation, safe 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. 2, a variety of ranges, users convenient debugging, lightning protection, the radio frequency interference. 3, with zero/full range adjustable options, can choose small integrated liquid crystal display (LCD). 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. Application characteristics of the industry; Star instrument explosion-proof type pressure transmitter is widely used in the following industry. 1, industrial process, pressure test, pressure calibration system in the laboratory. 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.
