Combustible gases are detected with catalytic beads. Sensor heads for combustible gases are certified
EEx de IIC T6 and can be connected directly to the 501 controller even if to be used in hazardous areas.
Fixed gas detection system for oxygen, toxic and combustible gases
The DIN – rail mounted modern controller saves space, money and installation time.

One safe controller for all gases: Any combination of a sensor head plus a controller is a complete gas detection system. This is what makes the Statox 501 so safe and reliable. The Statox 501 also gives you the opportunity to alter or expand existing systems with minimum expenditure.

Programs for any gas and measuring range are permanently stored in the memory of the controller. The user-friendly software program allows authorized personnel to select different configurations by a simple push of a button.

Easy to install and easy to use

The controller as well as the power supply and the common alarm module clip on to a DIN rail. The remote sensor heads and any alarm or recording devices connect to terminals on the front of the controller. The Statox 501 controller has three relays for alarm 1 and 2 and system failure （115 / 230 V AC / 2 A）. An analog output for recorder or process control systems is also included.

Measured values are displayed on a 4 digit LED-display. It is easy to program or calibrate the new 501 controller! Just follow the menu!

If sensor heads are to be installed in division 1 areas, they can be connected via intrinsically safe repeaters.

24 V power supply as well as the signals for the common alarm module are transmitted via bus from one controller to the next. All terminals are easily accessible from the front.

Field proven sensors for reliable gas detection

Compur manufactures electrochemical sensors for the detection of oxygen deficiency and toxic gases. These sensors generate an electrical current proportional to the actual gas concentration. The sensor remote heads are designed as intrinsically safe certified 4 - 20 mA transmitters and have an integrated concentration display.

Combustible gases can detected with a variety of catalytic beads （pellistors） or infrared technology. The sensor heads are certified and can be connected directly to the controller even if they are to be used in classified areas. The controller can supply and operate different designs of catalytic sensors. With so many possibilities, the system can easily be tailored to suit your individual application needs.

Easy maintenance saves time and money

Maintenance of the 4 – 20 mA transmitters is very easy. A one-man calibration or replacement of the sensors can be done without further precautions, even in classified areas.
