Audited Supplier
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.
The differential pressure setting can be changed without moving the cover plate.
Switch connection ratings: 5amp 125/250VAC 1/4 H.P., 125VAC Fine Silver Contacts.
