Rsknr:

Level alarm for oil, gasoline

or grease separators.

• Capacitive measuring principle
• ATEX certified
• High level alarm with extra probe

Separators for oil, gasoline or grease should have an alarm unit.

Separators for oil, gasoline and oil must be emptied in time. This is normally a requirement from the authorities. The separator alarm OSA gives an alarm signal so that the separator can be emptied before any hazardous liquid leaves the separator.

Application

The Afriso ema type OSA alarm system with capacitive and special thermistor type sensors is designed specially for use with gasoline, oil or grease separators.

Description

The OSA alarm system consists of a wall mounting control unit with two output relays, integrated piezo-electric buzzer and LED indicators, an ES4 capacitive probe for oil alarm,

and an optional R6-special thermistor probe for high level liquid alarm, both probes are EX certified.

Each probe is fitted with a 5 metre long cable, and is suspended in the separator chamber to the required level. The tip of the ES4 probe should be mounted 150 mm below the constant water level in the separator. At this setting the OSA will give an oil alarm for a gasoline or oil/grease layer of

150 mm.

The OSA unit will also provide a separate high level liquid alarm if fitted with the optional R6-special thermistor probe. The high level liquid alarm is given when the level reaches the R6 probe, for example if the separator outlet is blocked.

The control unit monitors both probes and provides audible and visual alarms at preset oil and high levels, or in the event of short circuit or open circuit in the probe wiring.
