Product Description

Product Description

1. Pressure torque is used to protect refrigeration or air conditioning equipment from increased breathing pressure or reduced exhaust pressure in the refrigeration compressor system.
2. The pressure torque is also used to start and stop the refrigeration compressor and the air-cooled condenser fan;
3. With SPDT contact mechanism, allowed fluid temperature :-10°C~+110 °C;
4. Manual control, no need to use other instruments for functional testing.

Differential Pressure Control Switch

Differential pressure control is commonly used in gas or liquid systems to control the pressure difference between gas/liquid pipelines and circuits. A typical application is to install the controller in the bypass pipeline near the system pump. When the system pressure difference increases and exceeds the preset pressure, the control valve will open, allowing more liquid/gas to pass through the side valve, which will reduce the pressure difference between these two pipelines in the water system. On the contrary, the pressure difference between these two pipelines in the water supply system will increase.

 

performance
 

The set point can be quickly determined by reading the scale directly.
The differential pressure setting can be changed without moving the cover plate.

Electrical parameters

Switch connection ratings: 5amp 125/250VAC 1/4 H.P., 125VAC Fine Silver Contacts.

Wiring instructions

working principle

In mechanical systems, the airbag interface of the controller is connected to the pressure port. When the pressure in the mechanical system exceeds the pressure set point of the controller, the contacts of the micro switch of the controller are disconnected, cutting off or connecting the circuit, and the machine stops or starts operating. When the pressure in the mechanical system drops to the set pressure difference of the controller, the contacts of the micro switch of the controller automatically reset, the circuit is turned on or off, and the machine restarts or stops operating. Therefore, pressure controllers play a protective and starting role in machinery, and are of great significance for the reasonable operation of machinery.
