Additional information

The Optima Plus advanced infrared point gas detector has been especially designed to detect hydrocarbons in potentially explosive certified atmospheres. This fixed gas detector can thus be used in a whole range of applications like offshore drilling platforms, petroleum and gas terminals, refineries, gas turbine-based power plants and so on.

 

Thanks to the integrated infrared gas detection technology, this detector features a very fast response time T50 below 3 seconds and T90 below 4 seconds for methane (CH4) detection. Moreover, the infrared gas detection principle offers a fail-to-safe operation to the detector.

 

As it uses the infrared absorption technology, the Optima Plus is immune to catalytic poisons, can operate in inert atmospheres and features a very long operation life. Moreover, in comparison with classic standard fixed gas detectors, the Optima Plus requires a reduced routine maintenance, which provides low ongoing cost of a gas detection system ownership.

 

In the core of this gas detector, the 4-channel optics block (dual compensated) has been especially engineered to provide the detector with the most stable optics design possible. Its integrated microprocessor controls the signal and offers an optimal safety level and the detector heated optic components reduce risks of condensation. Furthermore, in order to remotely monitor distant or inaccessible sites, the Optima Plus can be integrated into a remote gas sampling system. Its ultra-resistant housing made of stainless steel 316 is IP66 and IP67 approved against dust and water.

 

Lastly, the Optima Plus infrared gas detector features 4-20 mA output signals allowing the device to use the optional HART (Highway Addressable Remote Transducer) protocol. This communication protocol allows among other functions to perform bump tests, simulate alarm, fault or warning, configure alarm thresholds, inhibit, warning and overrange levels and to change target gas.

 

An optional duct mounting kit enables installation of the Optima Plus with a duct/ventilation system. It also enables functional gas testing without removing the detector from the duct system.
