Digital Electric Contact Pressure Switch for Construction Machinery

Product Description

Product Description:

MD-S925EM  is a multi-screen display digital electrical contact pressure gauge. The main screen displays the pressure change in real time. The two secondary screens display the lower and upper alarm values. Users can intuitively see the alarm pressure and real-time pressure changes. The user can adjust the pressure setting value conveniently and intuitively by pressing keys.

This product can choose axial and radial two installation methods, 304 stainless steel shell, dial size is 100mm.

This digital display electric contact pressure gauge is mainly to replace the traditional mechanical electric contact pressure gauge, so the output control method is the same as the traditional mechanical electric contact(One common line, one high alarm, one low alarm). The user can complete the wiring according to the wiring method of the mechanical electrical contact pressure gauge.

Because of the built-in pressure sensor, it is particularly suitable for use in situations with frequent pressure shocks and strong field vibration. With anti-vibration, long life, simple operation,Clear display and other characteristics.

At the same time, this digital display electric contact pressure gauge has a variety of pressure unit switching and one-click clearing functions.


Technicial Characteristics:
☆ Three-screen display (the real-time pressure is displayed on the main screen, and the upper and lower set values are displayed       on the secondary screen)
☆ 100mm dial, 304 stainless steel case, optional axial or radial installation
☆ Easy and intuitive setting of alarm points
☆ Switching of multiple pressure units, error clear function
☆ It is completely equivalent to the wiring method of mechanical electric contact pressure gauge
