The AST-I series of analog transmitters are high quality, industrial, dual beam, referenced transmitters with miniature infrared sensors, analog output and water / dust tight, corrosion resistant, non-metallic enclosures.
The AST-ICD detects carbon dioxide (CO2) with a choice of one of three different ranges.
The AST-IHC detects hydrocarbon - methane (CH4).
Care should be taken to not spray the sensor head. The sensor vent opening has a microporous PTFE filte attached which provides splash protection only, it is not designed to provide protection from the application of pressurized water.
Low power consumption
Dual temperature compensated pyroelectric infrared detectors
Fast response with accurate low-level gas detection
Long sensor life
Water / dust tight / corrosion resistant polycarbonate enclosure
Linear analog (4-20 mA) output
Target gases include CO2 and Hydrocarbon gases (HC): including Methane (CH4)
RoHS compliant circuit boards
