We can also provide temperature and pressure sensors for the compressor.

The oil sensors are available in a 24V AC/DC version, a 90…240 V AC version, as well as a high-temperature version. When you order an oil switch, you should also be aware that we differentiate between switches for PAO, M & E oil and PAG oil. These two items have different ordering codes, with “1” corresponding to PAO, M & E oil and “2” corresponding to PAG oil. If you want to read more about oil, please see our product catalogue on pages 189-196.
