Level monitoring OLC-D1-D

OLC-D1-D is an opto-electronic oil or liquid level monitoring using infrared light. It is mainly used for oil separators and pressure vessels and differs from the other types of OLC-D1 mainly by a different prism unit. It is mounted instead of a sight glass and consists of

a prism unit and
an opto-electronic unit (screwed into the prism unit, is integrated into the control of the system).

If the oil level is to be checked via a sight glass in addition to the opto-electronic monitoring, a Rotalock T-piece must first be fitted in place of the sight glass to allow parallel installation of the oil level switch and the sight glass (can be ordered with part no. 365 433 56). Position see
