Differential oil pressure switch DP
DP is a differential oil pressure switch used on compressors with oil pump in conjunction with the CM-RC compressor module. It is integrated in the bearing cover of the compressor.
- The DP-1 variant was used with the CM-RC-01 compressor module.
- The DP-2 variant replaces DP-1 and can be used with the CM-RC-01 and CM-RC-02 compressor modules.
DP-1 and DP-2 have the same functions and are interchangeable on the module.
The DP-2 uses the same sensor unit as the Delta-PII. The electronic units differ in their cable lengths.
Variant | Cable length | Electronic unit |
|---|---|---|
DP-1 | ||
DP-2 | 1 m | 347 317 21 |
1.2 m | 347 317 22 | |
3 m | 347 317 23 |
