Infrared Gas Sensors and OEM 4-20mA transmitter: Cirius and CiriusX
New: CiriusX OEM transmitter provides selectable 4-20mA source or sink
Our Cirius range of infrared gas sensors incorporate patented technology and our CiriusX OEM transmitter incorporates highly flexible software in a leading edge design. Using a novel optical technique our sensors offer high sensitivity to target gases whilst having an extremely small sensing volume. Housed in an industry standard 20mm diameter package they are available as "basic format" 7 pin sensors and "smart format" 3 pin sensors.
