Delta-P Delta-P-2 OPS1 OPS2 |
Products for the back of the electronic part, the need to increase the pressure on the front metal probe 300 yuan.
Product profile:
Electronic differential pressure switch P (Delta-P), P- II (Delta-P- II), OPS1, OPS2 electromagnetic principle, high / low voltage differential oil monitoring in the refrigeration compressor, when the pressure difference is within the rated range, and after the set time delay, output relay is triggered off, up to protect.
Product details:
The utility model is composed of two parts: a mechanical joint and an electric control component, and the internal mechanical movement part is not provided, the external LED state is displayed, and the external manual reset
Button, protection class IP54.
This product replaces the traditional use of high / low pressure capillary mechanical differential pressure switch, is the latest product upgrade.

KRIWAN research and developmentDELTA-PElectronic typeOil pressure differential switchRelay, mainly used in cooling compressor oil pressure difference. KRIWAN oil pressure differential switchDELTA-PThe electrical part of the relay can be disassembled without opening the refrigeration cycle.
Oil pressure differential switchElectronic oil pressure difference
Application of KRIWAN electronic oil pressure differential relay:
KRIWAN electronicOil pressure differential switchThe screw in part is directly screwed into the pump casing, and the KRIWAN electronic oil pressure differential relay is connected with the pump with low pressure and high pressure through the inner passage. KRIWAN electronic oil pressure differential relay electrical components can be removed without opening the refrigeration cycle.
KRIWAN electronicDELTA-PWhen the - is connected, the monitoring of the lubrication system is particularly important because of the unstable pressure ratio.
Order number: 22S630
Electronic differential pressure switch P (Delta-P), P- II (Delta-P- II), OPS1, OPS2
The principle of electromagnetism is used to monitor the high / low pressure difference of the refrigerant oil in the refrigeration compressor
After the delay, the output relay is switched off to play a protective role.
The utility model is composed of two parts: a mechanical joint and an electric control component, and the internal mechanical movement part is not provided, the external LED state is displayed, and the external manual reset
Button, protection class IP54.
This product replaces the traditional use of high / low pressure capillary mechanical differential pressure switch, is the latest product upgrade.
