This unit has been designed to monitor areas for oil leaks or spillages from plant and equipment containing diesel oil.

Suppled as a one or two alarm, the unit has a large digital display, audible warning, Mute alarm push button and common alarm relay for onward signalling. The system can also be supplied with, flashing Beacon or Beacon sounder, SMS text alarm messaging or email alarm message.

Sized at 180mm wide x 130mm high x 60mm deep the unit can be supplied as one or two zone systems designed to monitor critical areas for oil leaks and spillages via spot optical sensors from plant such as generators, tanks and other equipment containing oil. The unit can also detect leaks within pipe in pipe systems and bunded tanks using our PPS sensor. Up to 3 sensors can be connected to each zone.

The current alarm status is displayed on a large alpha numeric display. When oil touches one of the sensors the display will flash showing the zone number, an internal audible warning will sound, the common alarm volt free contacts will change state, if fitted, the remote beacon/beacon sounder will start, and if fitted, the SMS text messaging/Email unit will send an alarm message via the mobile network. If power to the unit fails, the internal volt free “common Alarm” BMS contact will change state. Oil leak monitoring in external areas can be achieved by using our OSPW sensor.

Features

  • The unit can be supplied as a 1 or 2 zone system
  • Oil sensors can be up to 100m away from the main alarm unit
  • Large back lit alpha numeric display
  • Except for mains power, all terminals are of the plug and socket type
  • On board audible warning device to alert local operators of a problem
  • Alarms latched until Mute operated to give indication of oil leak
  • Two common alarm relay contact for onward signalling to a BMS or other systems
  • Mains Power monitoring via the Common alarm BMS contact

This unit has been designed to monitor for oil leaks from pipes, tanks, generators etc. contained within buildings, containers or covered areas and displayed on the alpha numeric display the current zone alarm status. When oil touches one of the sensors the display will flash showing the zone number, an internal audible warning will sound, the common alarm volt free contacts will change state, if fitted, the remote beacon/beacon sounder will start, and if fitted, the SMS text messaging/Email unit will send an alarm message via the mobile network. If power to the unit fails, the internal volt free “common Alarm” BMS contact will change state. Oil leak monitoring in external areas can be achieved by using our OSPW sensor.

Sensor

The mode of operation is the principle of total internal reflection. An LED and photo-transistor are housed in a plastic (Polysulfone) dome. When no oil is present, light from the LED is internally reflected from the dome to the photo-transistor. When oil covers the dome, the effective refractive index at the dome-oil boundary changes allowing some light from the LED to escape. Thus, the amount of light received by the photo-transistor is reduced indicating the presents of oil.

Individual zone alarm relay contacts for onward signal to a BMS

Individual zone alarm relays can be provided to give a volt free normally open, closed in alarm contact that operates when the zone goes into alarm. The contacts can be used to onward signal to Building Management Systems or to control individual water valves.

Beacon

SMS text messaging or Email

For unmanned areas or to advise maintenance staff of a problem. With the addition of our SMS Text Messaging alert unit, an alarm will also be sent in text form to one or two phones. This unit is usually added where the alarm unit is mounted remote from maintenance staff, or in unmanned areas.
