The Oldham OLCT 60 by Teledyne detects; Oxygen, flammable, toxic and refrigerant gases. Equipped with a local display, access to the detectors menu is non-intrusive using a magnetic key, removing the need for a hot work permit when deployed in hazardous areas. Maintenance mode is locked to prevent accidental resetting.

Smart sensors can be removed by unscrewing the head of the unit and replaced by pre-calibrated sensors. Sensors can be moved to a safe area for calibration.

  • Explosion-proof XP or Intrinsically Safe sensor (toxic and O2 only).
  • Remote sensor version; OLCT 60AD model allows the sensor to be mounted up to 15 metres away, for detection in hard to access locations or in dangerous areas – Zone 0 or 20 (intrinsically safe version).
  • Infrared XP IR sensor or OLCT IR transmitter, for combustible and CO2 gases. Ideal for harsh environments such as refineries & offshore.
  • Note: IR sensors for LEL are now obsolete. The replacement is the GD10P and OLCT80 transmitter – if a local display is required.

Features

  • Sensors; Catalytic, electrochemical and semiconductor
  • 316L stainless steel, durable and corrosion-resistant
  • 4-20 mA analogue transmitter with display
  • Detects: Explosive, toxic gases, O2, VOC & Freons
  • Electrical supply:  16 to 30 V DC
  • SIL 2 compatible
  • IP66 dust and splash-proof
  • Smart sensors
  • Non-intrusive one-person calibration
  • Operating temperature: -20°C to +60°C
  • Size; 154 x 186 x 121 mm, weight 2.1kg
