Datasheet

Toxic Gas Detection with IR and Electrochemcial Gas Sensors

Features

Competitively priced for use in non-hazardous areas only

8 to 24 volt dc operation

Industry standard 4 to 20mA output

Plug-in sensor

MOptional plug-in handheld configuration unit

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.

Typical examples of their use are in water purification processes, food preparation and/or storage, car parks, swimming pools, medical applications.
