OEM Fiber Optic Signal Conditioner

FOTEMP1-H offers unique flexibility. Battery operated for maximum flexibility, the user can move easily from one measurement point to the next. The internal rechargeable battery offers continuous operation for at least 5 hours and be charged/operated with the supplied wall plug-in AC power supply.

The FOTEMP1-H single-channel, handheld signal conditioner features a large LCD display with LED backlight and RS-232 communication port for real-time data acquisition. It can be controlled directly using the front-panel keypad or the supplied “FOTEMP-Assistant” data logging software. One LED indicates battery charging status while second LED displays sensor status.

The TS series temperature sensors are completely passive, non-conductive, and thus immune to EMI, RFI, microwaves, high voltage and ground loops. Ideal for making temperature measurements in high electromagnetic field environments such as MRI, in microwave fields and other environments, where measurement with RTDs, thermocouples, and electronic-based temperature sensors is not possible.
