Gas Sensors series Xgard, TXgard, Flamgard
sensors for measuring gases (with display and output or gas sensors in combination with a stationary equipment to detect gases (with ATEX approval)

Here you can find ATEX-approved gas sensors for flammable gases (ex), oxygen and toxic gases for fixed mounting. These gas sensors vary by the type of gases they measure, functionality (e.g. analogue output, relay output) or the type of indicator - there are sensors with a built-in screen (as an indicator) or without. You will be able to choose a gas sensor for almost any type of gas: methane, propane, butane, pentane, LPG, ethanol, ethylene, nitrogen, acetylene, benzene (lead), phosphine, oxygen, ozone, carbon monoxide, carbon dioxide, hydrogen sulfide, sulfur dioxide, chlorine, ammonia (sensors for other types of gases can be requested). Sensors without a display (series Xgard) are used in combination with an external indicator or a facility to detect gases, e.g. with the Gasmaster. Gas sensors that operate without internal alarm relay can be used in conjunction with the GasFlag distributor.

Gas sensors
The series of sensors Xgard, TXgard and Flamgard is always delivered calibrated and registered. By default, the sensor is delivered calibrated to methane. Please consult us for other types of calibration.

GasFlag
We offer you the GasFlag for sensors without alarm relay. It is a small box for fixed installation without a display for signals for the input of 4… 20 mA. Its output has two alarm relays (max. 1 to 30 VDC). The status is displayed through the LED, and it is powered to 230 V.

Gasmaster
The Gasmaster is a power station of gas detection with a large display. There are several versions: 1 and 4 channels as well as with or without an interface for the PC. The Gasmater also possesses an alarm relay with which light signals or ventilators can be activated. The systems of the Gasmaster and the gas sensors are delivered configured, calibrated and verified.

Here you can find an overview of gas meters for the protection of humans.

Technical specifications of the gas sensors series Xgard IR (with infrared measuring)

Gas sensor type	Xgard IR (infrared)	Optional components for the Xgard IR
Image		The response time of infrared gas sensors is T90 <30 s and zero drift is approx. ± 2% per month. For getting highly accurate measurements and protecting the sensors exterior, there are some optional protectors. Depending on the installation site, the protector against sunlight may be the perfect option. If the sensors are mounted outside (in the open field) or in halls and pavilions that are frequently cleaned with water or disinfected from time to time, we recommend the water deflector protector. When the sensor is mounted in high humidity environments or offshore applications and vessel installations, we recommend the gas sensor with the cap resistant to rain. The cone collector is often used when you need to detect light gases (e.g. methane). This facilitates the entry of the gas into the sensor. If you have any questions, contact us : +44 ( 0 ) 2380 98703 0 Advantages to the conventional gas sensors: The great advantage of infrared gas sensors is their long life (>5 years) and almost inexistent long-term drift. This lowers the cost of calibration to zero Euros. In addition, the sensors have a full temperature compensation. The ATEX, IECEx and UL norms allow them to be used worldwide.

Technical specifications for the Gasflag

Warning station without display to connect one of the above sensors. This unit is usually mounted on the wall. When it exceeds the threshold value, it emits an alert tone and flashes a red alarm LED. A relay output can, for example, be connected to an omnidirectional illumination. The response time of the alarm is less than 1 sec. Threshold values can be adjusted. The alarm station is almost always used with a gas sensor. When it is not desired then the sensor itself makes the indication, and the alarm sounds.

Digital display and control panel for gas sensors described above. There are two Gasmaster models: GM 1 for a GM sensor, and 4 for up to 4 sensors (shows 4 values at one time). In addition to the standard analogue output, both types are available with an RS 232 data interface. The device also has relay outputs to activate a multidirectional light. The housing of the apparatus is protected against dust and splashing water.

The unit is standardly equipped with a battery so it will continue operating in case of a power failure.
