Dräger's product range covers a wide variety of types: catalytic bead or infra-red IR sensor technology point or open path detection increased safety, intrinsically safe or explosion proof analog 4 to 20 mA, digital HART or RS 485 signal output with or without local display with or without on-board relays low budget or high end equipment Your local representative will gladly help you determine the right product for your application
Based on patented innovations, the Dräger PIR 7000 combines maximum light-efficient optics with a signal-stabilizing 4 beam technology. The double-compensating construction is characterized by the greatest possible robustness towards interferences (e.g. dust and dirt deposits). Due to its non-imaging nature, the measuring signal of the Dräger PIR 7000 remains unaffected by a partially covered beam. It can thus be ensured that the instrument fully complies with the requirement "no false alarms" .

Fastest warning for explosion hazards
With bright alarm LEDs and a loud buzzer the transmitter CC28 (ATEX) warns of combustible gases. This avoids expenses for additional Ex-proof buzzers and Ex-proof alarm lights and their costly wiring.
The improved sensor technology and a special „chimney effect“ make the CC28 the catalytic combustion transmitter for combustible gases with the shortest response time worldwide. The proven delta alarm of GfG’s GMA controllers reduces the response time even further – a very important feature particularly for handling explosion dangers. This gives the user important seconds to take counter measures or to get to safety.
Adjustments are done directly at the transmitter by means of touch keys (one man calibration) without opening the casing. An optional remote control facilitates inspection, service and calibration considerably, e.g. if the transmitter is mounted close to the ceiling; you do not have to climb up a ladder.
The gas concentration can be read directly at the transmitter, at the remote control and at the controller. Alternatively you may decide for a low-cost model of the CC28 without display or alarm.

The effectiveness of SIMTRONICS remote detectors (accuracy, fast response time and high reliability) guarantees the ultimate protection against the risks associated with gases in industrial environments.
The housings are given a special surface treatment to improve their resistance to corrosion (stainless steel or aluminium housings).
The measurement process is based on OXYCOL™ low temperature catalytic oxidation, enabling detection of all combustible gases and gives the detector an extremely long lifetime.
All the explosimeters are equipped with :
• An exclusive system of alarm verification in case of scale overrun,
• A linear response,
• A high stability,
• A very short response time.
The interchangeable and removable cartridges (as well as the support independent from the electronic box) make the remote detector easy to use and maintain.
All commands, configurations and readouts are remotely accessible using the infrared remote controller.

GfG's fixed gas detection systems are available as easy to operate single point units or as larger systems with several hundred transmitters. These multiple point systems consist of controllers and transmitters that communicate with each other. The transmitter changes the measured gas concentration to an electrical signal which is transfered to the controller. The controller shows the gas concentration in a display and immediately activates alarming devices in case of a gas leak. Advanced features such as data logging or online data transmission allow the user to easily monitor ambient changes in the environment. The Stand Alone unit is a combination of both transmitter and controller. GfG controllers are designed to operate any transmitter offering either a 0,2-1 mA or a 4-20 mA signal. The controller processes the electrical signal received from the transmitter. It evaluates and displays the measured gas concentration. All controllers offer three on board relays that will be activated if the gas concentration exceeds the alarm level. All controllers are available as 1 or 4 channel controller. This means that either one or up to 4 transmitters detecting the same gas in the same range can be connected to one controller.

SIMTRONICS “TT63ES” detector is a semi-conductor sensor type with a very low cross sensitivity to other gas.
The basic principle is the resistance variation of a tin oxide semi-conductor. The inflammable gas reacts with the oxygen absorbed at the surface of the semi-conductor, and causes the electric resistance to decrease. The nature of the semi-conductor, its doping and its service temperature contribute to better detectivity of certain gases.
When other semiconductor on the market need to smell gas every week to avoid the sensor to fall asleep, the SIMTRONICSsemiconductor sensor only needs a six-month or one year calibration test.
Modern electronics provides high performance for humidity and temperature rate compensation and long term stability. The circuits ensuring the supply to the sensor, the amplifier and the interface are grouped in the flameproof enclosure onto which the detection probe is secured.
