Characteristics: Simple structure but stable performance. The measure range is specialized designed for the hydropower plant. Under the wide range, the dead zone is less than 0.1Mpa. With lock nut, the setting can be kept stable. As there are wire converted terminals, it's easy and convenient for wiring.
Profile:
The single-valued type pressure switch is widely used for the water, gas and oil’s pressure control. When the
pressure is higher than the setting value, the pressure will make the constant spring deformation, which makes the
micro switch action and export contact signal (only can be set a setting value), thus realize alarm and control.
The single-valued ordinary type pressure switch has a simple structure and stable performance. It has the
features of good long-term stability, and also with the function of locking the adjusting nut. Even if the switch
long-term works in the vibratory occasions, it also can keep stable setting value.
