GENERAL
OMS-1 is an alarm device for monitoring the thickness of the oil layer
accumulating in an oil separator. The system consists of OMS-1 control
unit, OMS sensor and a cable joint.
Figure 1. Oil separator supervision with OMS-1 alarm device
OMS sensor is installed into the light liquid storage chamber and gives
an alarm when the chamber oil layer reaches a pre-determined level.
The sensor is normally immersed in water.
The function is based on the measurement of the electrical conductivity
of the surrounding liquid
– water conducts electricity much better than
oil.
Oil separator is regarded as potentially explosive (Ex) area. OMS-1
sensor can be installed in a zone 0, 1 or 2 potentially explosive area but
the control unit must be mounted in a safe area.
The LED indicators, push button and interfaces of the OMS-1 control
unit are described in figure 2.
