OpSens’ OTG-M Series fiber optic temperature sensors (OTG-M170, OTG-M220, OTG-M360, OTG-M420, OTG-M600, OTG-MPK5, and OTG-MPK8) provide outstanding performance. The OTG-M Series temperature sensors use a tried-and-tested temperature transduction framework based on the temperature-dependent bandgap of Gallium Arsinide (GaAs) crystal.
Due to the tiny GaAs crystal situated at the tip of an optical fiber, this sensor type is useful for tip measurement systems. Each model of the OTG-M series is distinguished by its response time and sensor diameter (OD).
When merged with OpSens’ SCBG signal conditioning technology and the advantages of measuring with light, the OTG-M Series provides unprecedented continuity and consistency in the harshest conditions, like elevated levels of EM, RF, MR, and microwave field settings.
The OTG-M Series is built with industry-standard optical fiber and is compatible with all OpSens SCBG signal conditioners. This compact and dependable fiber optic temperature sensor can be customized for OEM or customer-specific systems, and it is available with a range of optical cables and sheath options.
