Combustible gas detector – Explosimeter

The Dräger combustible gas detector is suitable in many situations. While it is the ultimate tool for firefighters, it is also used in the "oil and gas" sector or in the mining industry.

ATEX zone 0 approved, the Dräger portable combustible gas detector is equipped with an Ex catalytic sensor which has excellent resistance to silicone poisoning and hydrogen sulfide. The sensor has an 4 years lifespan.

The Xam-EXPLO is very light and ergonomic. An external pump can be associated with it, which then makes it possible to detect explosive gases without entering the concerned room.

The Dräger combustible gas detector Xam-EXPLO has a 12 hours autonomy after only a 4 hours charge.

Especially designed for use in hazardous atmospheres, the X-am 2500 portable multi gas detector is ATEX approved for zone 0 (permanent explosive atmosphere). This small 4 gas monitor can accurately and reliably detect the presence of up to 4 gases among O2 (oxygen), CO (carbon monoxide), H2S (hydrogen sulfide), NO2 (nitrogen dioxide) and SO2 (sulfur dioxide).

The powerful tiny sensors of the X-am 2500 multi gas detector allow safe and reliable detection of hazardous gases concentrations. Thus these high performance gas detection sensors are ideally well-suited for industrial applications and refineries. Moreover, thanks to their unique design, these gas detection sensors feature a long-lasting shelf life – up to 5 years for O2, CO and H2S sensors. This high sensor durability then enables reduction of gas detection related operating costs.

Thanks to its compact and lightweight design associated to a robust crocodile clip, the X-am 2500 portable 4 gas monitor can be easily and comfortably worn on a belt or on a collar without disturbing the user. Moreover, this portable multi gas  detector features several gas entries on the top and on the front in order to properly operate even if the device is inside a pocket or if one of the entries is accidentally covered. As a safety device against potentially dangerous gas concentrations, the X-am 2500 has a 3 years guarentee to ensure maximum security to its user.

The X-am 2500 portable gas monitor  features a large easy to read LCD display. All of the target gases are simultaneously displayed on the screen and once a gas alarm occurs, the hazardous target gas is highlighted for fast recognition of the hazard. The ultra-bright visual alarm can be seen at 360° and is coupled with acoustic 90 dB at 30 cm and vibrating alarms.

An optional gas sampling pump is available to draw remote samples up to 30 meters in order to get sure of gases concentrations in confined spaces like tanks or pits before any intervention. This gas sampling pump, designed for this 4 gas monitor, automatically triggers upon the device start-up and it is very easy for the user to switch from pump mode to diffusion mode without any tool.

The X-am 5600 portable multi gas detector is a personal protective equipment that has been especially designed to simultaneously detect from 1 up to 6 gases. Thanks to an innovative combination of infrared and electrochemical gas detection sensors, this portable gas detector can quickly, reliably and accurately detect the following gases: O2, Cl2, CO, CO2, H2, H2S, HCN, NH3, NO, NO2, PH3, SO2, amines, Odorants, COCl2, Ozone and different organic vapors.

The X-am 5600 has been designed to combine performance and discretion. This way, thanks to a compact size and a light weight, it won’t annoy its user. Easy to wear and to use, this portable multi gas meter is robust and can be used in hostile industrial environments. IP67 certified, it is resistant to water and dust. Moreover, thanks to its rubber housing, this personal gas monitor features an increased resistance to impacts and shocks for use in difficult conditions. As it also features a crocodile clip, it can be easily be attached to a pocket or a collar in order to monitor concentrations inhaled by the operator.

The X-am 5600 multi gas meter can monitor up to 6 gases thanks to electrochemical and infrared sensors. Because of their huge durability and resistance, infrared gas detection sensors can operate for up to 8 years and only require one annual calibration. Thus reducing maintenance and operating costs. This way, this detector can be equipped with an IR Ex sensor to monitor combustible gases (with a measuring range between 0 and 100% of the volume for methane, ethylene and propane for example), an IR CO2 sensor to detect carbon dioxide or an electrochemical sensor for hydrogen detection.

When equipped with an external sampling pump – available in option – the X-am 5600 can draw remote samples up to 30 meters away in order to get hazardous gas concentrations before any intervention. This system is very convenient before any entry in confined spaces like tanks or pits.

Lastly, this lightweight and compact detector is ATEX approved for use in zone 0 - continuous explosive atmosphere.

Thanks to the wide variety of sensor technologies that can be used with this monitor, the OLCT100 fixed gas detector can detect a large range of gases. The combustible gases can be detected with a catalytic or infrared sensor, toxic gases with an electrochemical sensor, freons with a semiconductor sensor and carbon dioxide with an infrared sensor.

Two outputs types are available for this fixed gas detector range. The first one is the 4-20 mA analog output. It can be used to detect combustible, toxic and asphyxiating gases but also solvents, freons or carbon dioxide. The second output version is a Wheatstone bridge for the detection of combustible gases (0-100% LEL only).

Many accessories are available for the OLCT100 gas detector to improve sensor response time or to get optimal implementation.

The OLC/OLCT100 range is available under 5 versions:

• OLC100 : Wheatstone bridge output detector to detect the combustible gases (0-100% LEL only)
• OLCT 100 XP: Explosion-proof version equipped with a catalytic, electrochemical or semiconductor sensor to detect the combustible or toxic gases or oxygen.
• OLCT 100 IS: Extremely reliable version to detect toxic gases or oxygen.
• OLCT 100 XP IR: Explosion-proof version equipped with an infrared sensor to detect the combustible gases or CO2
• OLCT 100 XP HT: High temperature explosion-proof version to detect combustible gases up to 200 °C

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.
