Acid detector in refrigerating compressor oil - comprises electrodes fixed in housing in place of oil drain plug

摘要

Acid is detected in the oil of a semi-hermetic refrigerating compressor using a pair of electrodes immersed in the oil bath. These are fixed in the housing via a pressure-resistant screwed joint, inserted in place of the oil drain plug. ADVANTAGE - Permanent monitoring of acid level and immediate warning of excessive amount.
