Reliability

• The OLCT IR is a highly reliable infrared gas detector.

• SIL2 capable according to the standard EN 50402, the OLCT IR has a probability of failure on demand (PFD) of 0.0016.

• Mean Time Between Failure (MTBF) is 28 years.

Efficiency

• Based on the infrared absorption principle, the OLCT IR offers significant advantages when compared to catalytic detectors. Its dual source, four-beam technology further improves the unit’s performance over other infrared detectors.

IR Technology:

• Quick response time

• Operates in oxygen-deficient atmospheres

• Fail safe

Measure without contact:

• No alteration of optical elements

• Minimal maintenance

• Resistant to poisons

Double sources / 4 beams:

• Compensation for dirty optics

• No long term drift caused by source and optical detector aging
