FOTEMP1-MINI (OEM Mini Signal Conditioner)



OEM 1-Channel Mini Signal Conditioner Module

The FOTEMP1-MINI  is a small form factor (SFF) OEM PCB interface module designed for low cost insertion of high performance GaAs-based fiber optic temperature sensing technology into OEM applications where common electrical temperature sensors and thermocouples cannot be used.  The SFF profile is ideal for embedded medical, life science and energy applications such as:

  • MRI, requires immunity to magnetic fields
  • CT, requires non-metallic design and minimal contrast
  • Switchgear and Transformers, requires electrical isolation and immunity to electrical fields 

The OEM Mini Module 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.
