OTG-MPK8 Fiber Optic Temperature Sensor

High accuracy SCBG-based fiber optic temperature sensor for tip measurement applications.

Opsens Solutions’ OTG-MPK8 fiber optic temperature sensor offers the highest performances and robust packaging in the industry. The OTG-MPK8 sensor uses the well proven technique based on the temperature-dependent bandgap of GaAs crystal as the temperature transduction mechanism. Its small sensing GaAs crystal located at the tip of the optical fiber makes it convenient for tip measurement applications. The OTG-MPK8 temperature sensor is housed in a robust PEEK tube hence facilitates insertion and daily handling.

Combined with Opsens Solutions’ SCBG (Semiconductor Bandgap) signal conditioning technology and with the inherent advantages of fiber optic, the OTG-MPK8 delivers unprecedented repeatability and reliability in the most adverse conditions such as high level of EM, RF, MR, NMR and microwave field environments.

The OTG-MPK8 is made with industry standard optical fiber and is compatible with all Opsens Solutions’ SCBG signal conditioners. This robust fiber optic temperature sensor is available with different optical cables and sheath options and is customizable according to customer specific applications or for OEM-type applications.
