ANALOX 5S MkIII Carbon Dioxide Sensor

The 5S MkIII is an OEM carbon dioxide transducer. Supplied housed in an aluminium enclosure, it has a five wire connection with 8 to 36v DC input and a 0 to 2v or 4-20mA output. The 5S3 comes complete with a flow adaptor to allow sample gas to be passed over the infra-red bench. Advantages of the 5S3. There are a number of performance advantages to the 5S3 sensor as well as user benefits: Detector: The 5S3 is an advanced, solid state infra red transducer utilising high quality optical components to ensure that measurements are specific to carbon dioxide with virtually no sensitivity to other gases. Temperature compensation. This is achieved using unique smart detector technology, further enhanced by the addition of a temperature sensor mounted within the infra red bench, minimising mesaurable temperature effects in the operating range. Pressure compensation. An onboard barometric pressure sensor allows automatic compensation of measurements for variations in atmospheric pressure. Drift compensation. Smart drift compensation actively monitors the infra red energy arriving at the detector via a dedicated reference channel. DSV Bibby Topaz has recently tested the 5S3 transducers and found it to have an improved accurancy compared to previous models - read their case study report. For anyone using the 5S MkIII within an OEM application then please read the ' OEM user sensor comms protocol' . The 5S3 is a direct replacement for the 5S MkII and can be retrofitted - just look out for the 5S3 foil logo. Available in both ppm and % variants.
