OLCT 60

Introducing the OLCT 60, a new generation of high quality gas detectors which covers all industrial needs for a variety of applications.

The OLCT 60 Series is composed of several versions:

  • XP or IS sensor (toxic or oxygen versions)
  • Remote or on-board sensor.

The OLCT 60AD version allows the sensor to be installed remotely up to 15 meters (standard), allowing detection in inaccessible locations, or in Zone 0 in the case of the intrinsically safe (IS) version. The detector units are made of 316L stainless steel, and are rugged and resistant to corrosion. Pre-calibrated sensors can be disconnected by turning the head of the unit. These “smart” sensors can be calibrated outside hazardous areas.

The OLCT 60 is equipped with non-intrusive access to a safe menu. In hazardous areas, calibration can be done with an operating mode in accordance with safety rules.

  • Access to maintenance menu
  • Pure air injection
  • Zero validation*
  • Standard gas injection
  • Calibration validation taking into account the usage rate*

All of these tasks can be carried out without opening the detector, using a unique magnetic key. Access to the maintenance mode is protected to avoid accidental reprogramming of the unit. The units are available at either 230 V AC, 125 V AC or 24 V DC.

* Automatic adjustment of zero and sensitivity
