Features 

  • Standard ranges 0-100ppm or 0-1000ppm Ammonia NH3. 
  • Suitable for use in Zones 1 and 2 hazardous areas. 
  • Two wire connection. 
  • 8 to 24 volt dc operation.

  • Digital display. 
  • Single operator calibration.

The FGD 3 Ammonia Gas Detector uses electrochemical sensor technology to detect the level of Ammonia in the atmosphere over the ranges 0 – 100ppm or 0 – 1000ppm. The detectors use the industry standard 4-20mA current loop both to power the detector and to convey the gas levels detected to a separate control unit such as the Status Scientific Controls MCU Series. This means that under zero gas conditions 4mA is drawn from the supply, and under full scale gas conditions 20mA is drawn from the supply. The current varies linearly for gas levels between zero and full scale. The detector head uses a two-wire connection.

  • Marine version available. 
  • Optional weather guard available. 
Description
 
The FGD3-IR Infrared Carbon Dioxide Gas Detector incorporates the latest generation of compact sensors incorporating infrared technology for the accurate detection of Carbon Dioxide concentrations over various ranges up to 100% volume. The detectors use the industry standard 4-20mA current loop to convey the gas levels detected to a control unit. This means that under zero gas conditions 4mA is drawn from the supply, and under full scale gas conditions 20mA is drawn from the supply. The current varies linearly for gas levels between zero and full scale. The detector heads use a three-wire connection. While the loop current supplies the power required by the detector head electronics within the detector head, a second supply must be provided to power the infrared sensor and its associated circuitry. 
 
Marine Version 
 
A marine version of the FGD3-IR is also available. This version is housed in a cast aluminium enclosure to provide higher RFI immunity where high power portable radios are used in the close confines of a vessel. The enclosure is plated and painted in order to withstand the harsh salt spray environment of the marine industry. The digital display is fitted with a sliding stainless steel front cover which remains over the display window when not being viewed thereby maintaining the RFI shielding properties of the enclosure during normal operation. 
 
FGD3 Weatherguard 
 
An optional weather guard is available for installations exposed to the atmosphere or contaminants and is also suitable for use in other areas where hosing down takes place. The weather guard reduces the possibility of water or other contaminants entering into the gas sensor thereby improving the overall reliability of the gas detector in harsh environments. The weather guard is attached with tamperproof screws to ensure that it is not inadvertently removed.
