OEM Fiber Optic Signal Conditioner

The FOTEMP-OEM is a small form factor interface module designed for convenient integration of high precision GaAs-based fiber optic temperature sensor technology into OEM applications where common electrical temperature sensors and thermocouples cannot be used.

This OEM interface product is compatible with all TS series fiber optic temperature probes. The sensors are entirely non-metallic and electrically passive, providing immunity to EMI, RFI, NMR, microwaves and radiation is required.
