HXT200 series sensors are dry ceramic capacitive pressure sensors which are made of ceramic materials and refined by special process by E+H Company. Ceramic is a kind of recognized high elasticity. Resistant to corrosion. Resistant to wear and tear. The thermal stability of ceramic capacitors enables the temperature range to be as high as -40-120, with high precision measurement. High stability. Its biggest characteristic is that the range can be as small as 700a. the anti-overload capacity can reach 100 times of the range, completely solve the other types of sensors without a small range and in a small range when the overload capacity is poor shortcomings, in addition to the range of the general sensor, its most distinctive positive and negative gauge pressure function. The whole machine has been strictly assembled and tested. It has advanced design principle, complete varieties and specifications, easy installation and use, beautiful appearance and so on. In order to meet the demand of domestic automation level, the intelligent series developed by our company is a kind of intelligent transmitter which is suitable for Chinese national conditions, and has very strong use value. At present, this series of products have been widely used in petroleum, chemical industry, metallurgy, electric power, food, paper, medicine, machinery manufacturing and other industries.
