EA-SK Intelligent digital pressure transmission controllerDetailed product description：

The EA-SK intelligent digital pressure transmission controller is a multifunctional product that integrates pressure measurement, display, control, and transmission. This product adopts microcomputer digital technology, with a high-performance pressure sensor with an isolation film filled oil core at the front end. The input signal is amplified by a high-precision, low-temperature drift amplifier circuit and processed digitally by a microcontroller to achieve operation/display/control/transmission, and can be controlled/transmitted simultaneously. It is easy to use and widely used in industries such as power, water treatment, petroleum, chemical, metallurgy, machinery, plastics, air conditioning equipment, etc. It can detect and control the pressure of media and is an ideal substitute for pointer instruments. It can be used as a base type instrument or in automatic control systems.

The EA-SK intelligent digital pressure transmission controller has high brightness digital display, strong anti-interference ability, and prevents relay shaking and misoperation at the critical point of pressure control, resulting in high product reliability. Each control output point has a normally open contact, a normally closed contact, and an alarm indicator light, making it flexible to use. We can produce products with single point control and dual point control according to user requirements, and also provide multiple standard transmission output signals.
