METHOD FOR MONITORING THE OIL LEVEL OF AN OIL-LUBRICATED COMPRESSOR, OIL LEVEL MONITORING SYSTEM FOR CARRYING OUT THE METHOD AND COMPRESSOR SYSTEM HAVING SUCH AN OIL LEVEL MONITORING SYSTEM

摘要

The invention relates to a method for monitoring the oil level of an oil-lubricated compressor, comprising the following steps: reading at least one oil level sensor (21, 21a, 21b), by means of which an oil level representing the compressor oil level is detected; checking compliance with at least one predetermined verification criterion for verification of the read-out oil level; and relaying an oil level signal if the read-out oil level complies with at least one relaying criterion (10a, 10b) according to whether said oil level reaches or falls below a predetermined oil level and with the at least one verification criterion.
