OEM 1-Channel Fiber Optic Signal Conditioner PCB Module

The FOTEMP1-OEM-MNT is a small form factor PCB interface module designed for low cost insertion of high precision GaAs-based fiber optic temperature sensor technology into OEM applications where common electrical temperature sensors and thermocouples cannot be used.

The 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, MR, microwaves and radiation is required.
