FOTEMP1-H offers a unique variety. Battery operated for maximum flexibility, the user can move easily from one measurement point to the next. The battery of the handset offers continuous operation for at least 5 hours of electricity and can additionally be loaded with a power supply.
The FOTEMP1-H, Single-channel handheld signal conditioner features a large LCD display with LED backlight and comes with an RS-232 communication port for real-time data acquisition. It can be controlled directly using the front-panel keypad or using the “FOTEMP Assistant” software. One installed LED shows the battery charging status and a second LED the operational readiness of the connected sensor. Temperature can be measured in high electromagnetic interfered environment, in microwave fields and other environments, where measurement with electric temperature sensors is not possible.
The outer jacket of the fiber optic temperature sensors is made out of teflon, at the sensor tip a GaAscrystal (gallium arsenide) is attached. The probe sensor is completely non-conductive. Optocon’s fiber optic sensors offer complete immunity to RF and microwave radiation with high temperature operating capability, intrinsic safety, and non-invasive use. The probes are also designed to withstand harsh and corrosive environments.
Starting at a light wave length of 850nm GaAs becomes optical translucent. Since the position of the band gap is temperature dependent, it shifts about 0.4nm/ Kelvin. The measurement device contains a light source and a device for the spectral detection of the band gap. This guaranties fast, repeatable and reproducible measurements.
