Oldham OLCT 80 Fixed Gas Detector

The Oldham OLCT 80 gas detector by Teledyne provides wireless connectivity in ATEX 1 zones, eliminating the need for wiring.

A versatile transmitter supporting all gas detection principles: catalytic, electrochemical, infrared and semiconductor. Compatible with all Industrial Scientific sensors. Available in wireless or non-wireless versions.

The transmitter is housed in epoxy-coated aluminium, and the sensor is housed in stainless steel. The local display shows readings, and four lamps indicate status: green shows operation ok, yellow denotes fault and red for alarm.

A single fault relay and two gas alarm relays are included, operated by the sensor electronics or supplementary inputs or from the MX62 central unit or the control system to which the sensor is connected. The OLCT 80 can serve as a standalone unit, an indisputable advantage in a classified explosion risk zone.
