Intelligent digital pressure controller BPK104-23

Intelligent digital differential pressure controller BPK104-23 I. Introduction intelligent digital differential pressure controller is a differential pressure measurement, display and control multifunctional products. Using high-precision pressure sensor as the detection element, together with the high stability circuit generates a switching signal, continuous pressure measurement and switching control. The product has high precision, small hysteresis, fast response, reliable performance, easy operation and installation easy and flexible benefits. The product is widely used in pressure chemical, mechanical, hydrological, electricity and other gas liquids line control, external relays can perform a variety of control functions.
