Product details

The MD-S900E pressure controller is a digital pressure controller with a 100mm 304 shell. It is a high-precision intelligent controller that integrates pressure measurement, display, and control. It is mainly used for fully automatic control operation in various industries such as water treatment systems, electromechanical equipment automation, engineering machinery, medical equipment, etc.

Can measure media such as water, air, hydraulic oil, etc. that are non corrosive to stainless steel.

The main functions implemented are low voltage closure and high voltage disconnection (or low voltage disconnection and high voltage closure);

In the system functions, password protection, reverse control, leakage protection, time protection, delayed action and other functions can be set.


Two pressure control points with upper and lower limits can be freely set and adjusted to meet different control requirements

4-digit LED real-time digital display of pressure value, convenient for users to observe.

Three types of pressure units are available for switching.

Built in relay signal output and anti backlash setting to avoid frequent actions of the controlled equipment.

The service life is longer than traditional mechanical switches, and long-term use will not cause malfunction or ineffectiveness.

The control accuracy is higher than traditional mechanical switches and there is no noise.

Strong shock resistance, anti-interference, fast response, and stable performance.
