Safe Area Gas Detectors - Loop Powered FGD4 Series of 4 To 20mA Transmitters
The FGD4 series of gas detectors are powered from an 8 to 24 volts dc power supply using the industry standard 4 to 20mA two-wire current loop to transmit the gas level to a separate control panel such as the Status Scientific Controls LC Series. The Carbon Dioxide version uses Infrared gas detection technology and requires a third connection to power the infrared sensor.
Note - These gas detectors are not certified for use in potentially explosive atmospheres and therefore must only be used in applications where it is known that potentially explosive gases do not exist.
Typical examples of their use are in water purification processes, food preparation and/or storage, car parks, swimming pools, medical applications.
They are available for detection of the following common gas types:
Ammonia, Carbon Dioxide, Carbon Monoxide, Chlorine, Ethylene Oxide, Hydrogen Chloride, Hydrogen Sulphide, Nitric Oxide, Nitrogen Dioxide, Oxygen, Sulphur Dioxide.
