Toxics Gases

Transmitter EC28

The smart transmitter

Whereven hazards are to be expected, the transmitter EC28 and GfG's proven monitoring systems are the right choice for reliable surveillance. The ATEXcertified design, an integrated, Ex-proof buzzer and bright alarm LEDs provide highest safety including visual and audible alarm even in hazardous areas. Thus the gas alarm does not only alert the man in the control room but also the person at site.

  • Reading of gas concentration at transmitter display
  • Ex-proof visual and audible alarm
  • ATEX certificate II 1 G EEx ia IIC T4 / II 2 G EEx em [ib] IIC T4
  • One-man calibration at transmitter by means of touch keys or remote control
  • Plug-in Smart Sensor - Sensor replacement without opening of casing





CI 21 Transmitter

Low Maintenance Ammonia Detection

The charge carrier injection (CI 21) sensor is a progressive development to improve upon current ammonia refrigeration detection methods. With CI 21 technology sensor life is no longer limited to ammonia exposure levels. This reduces replacement costs associated with electrochemical sensors.

Charge carrier injection technology also eliminates false alarms frequently associated with metal oxide sensing (MOS). These, along with other features, provide reliable, cost effective, longterm safety.

The CI 21 transmitter is an advanced development to which all other ammonia transmitters will be compared.

  • Stable long-life charge-carrierinjection sensor
  • Sensor is unaffected by exposure to high gas concentrations
  • Low temperature operation to -40oF
  • Low cross-sensitivity
  • Eliminates costly false alarms
  • Low cost of ownership





Transmitter IR 24

Stationary monitoring of carbon dioxide (CO2)

The IR 24 does not contain any moving parts, which may be subject to wear and tear. This ensures a long lifetime and low maintenance cost. Additional safety is provided by the permanent self-check and function test of the GMA controller. Sensor and electronics are protected in a solid enclosure from dust and water according to IP 54. This ensures that water cannot enter the detector, even in wet environments.

Behind a service lid on the front of the IR 24 you find potentiometers and test connectors for easy adjustment of zero point and span. This allows one-man calibration on-site and reduces service down-time.

  • Selective NDIR detection principle
  • Long sensor life for low follow-up cost
  • Easy handling
  • Signal output either 0.2 .. 1 mA or 4 .. 20mA
  • Potentiometers for easy adjustment of zero point and span
  • Connectors for test of output signal
  • Solid aluminium casing, IP 54
  • High reliability and repeatability of measurement results





CS 21 Transmitter

Low Cost Solid State Sensor

The CS 21 transmitter uses the proven chemosorption detection principle for detection of toxic gases, vapors and combustibles. The rapid response of the transmitter provides opportunity to take counter measures and thereby limit damages. The long life of the sensors makes the CS 21 a low-cost solution for your detection needs. A transmitter can be continuously operated for more than 5 years

  • High sensitivity to a broad range of refrigerants
  • Long sensor life
  • Fast response





EC 36 Transmitter

SAM Smart Area Monitor EC 36 - Stand alone

The EC 36 is a stand-alone transmitter. In every EC 36 there is a sensor, control electronic and relays for triggering of alarms. LEDs in the front panel immediately indicate the alarm. The signal output is provided as a 4..20 mA signal.

The EC 36 is the most enhanced single point gas detector available offering features never known to the industry. Equipped with AutoCal, the EC 36 can be comfortably calibrated in a matter of seconds. A 17 mm high backlight LCD-display indicates the gas concentration, status report and, if operated in service mode, all settings. In applications where the display of the EC 36 cannot be read because of its mounting position, a remote display is easily connected to an interface. Using the remote control, nonintrusive remote calibration can be performed, making forklifts or ladders a thing of the past.

  • Integrated alarm control
  • 3 alarm relays
  • AutoCal for easy and fast calibration
  • Illuminated 4-digit LCD display for easy reading
  • Extremely rugged casing
  • Remote control and remote display even for Exendangered areas
  • Smart Sensor Technology





GMA 200-MT Controller

  • A variety of trnsmitters can be connected for measurement of combustible, toxic gases/vapors and oxygen
  • Multiple relay configuration
  • Flexible, reliable and economic
  • Intuitive, backlit graphical LCD with "traffic light funcion" (green, amber, red)
  • SIL certification
  • DIN rail mounting or wall mounting
