This multi-channel device together with the TSTrafo temperature probe enable accurate and precise measurements of Trafo windings. By direct installation of the sensors in the windings real, current and quick monitoring is possible.
Through the use of gallium arsenide (GaAs) no recalibration is necessary throughout the product life time. The fiber optic thermometer FOTEMPTrafo is available with 1-8 measurement channels. The compact unit size and the height-adjustable DIN-rail-clip provides an easy installation in the cabinet. A wide selection of interfaces makes communication even easier. The choices are: RS-232, RS-485, USB, Relay, Analog output, WLAN or SD card that ensure an optimal connection. A fast measurement speed of 250ms* per channel allow the direct detection of overloads.
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.
Via the analog outputs and thanks to its accompanying software “FOTEMP Assistant”, measurement results can be easily controlled and monitored.
