Profile: Optocon AG specializes in the production and marketing of fiber optic temperature sensors & fiber optic signal conditioners for temperature measurement. Our products include fiber optic temperature probes and fiber optical accessories. Our GaAs thermometers can be used with all GaAs-based fiber optic temperature sensors. Our gallium arsenide (GaAs)-based fiber optic temperature measuring devices (FOTEMP) can be used with all GaAs fiber optic temperature sensors. All fiber optic thermometer (single-channel to multi-channel thermometer) are ideally suited for temperature measurement in high electromagnetic interfered environment, in microwave fields, laboratories and transformers. The fiber optic thermometers are available with different number of measurement channels, and with different interfaces for communication, thus enabling a real-time data acquisition. Our fiber optic temperature sensors offer complete immunity to RFI, EMI, NMR and microwave radiation with high temperature operating capability, intrinsic safety, and non-invasive use. The fiber optic temperature probes are also designed to withstand harsh and corrosive environments.
