Optical fiber thermometer suitable for power applications. Continuous temperature monitoring of switchgear and busbars without being affected by electromagnetic noise.
OSENSA's optical fiber temperature sensors for power and medical applications enable reliable temperature monitoring without being affected by noise in environments with EMI/RFI and high voltage. This product is suitable for continuous temperature monitoring of switchgear contacts, busbars, and critical connections. <Product Basic Configuration> - Temperature sensor probe (PRB-110 / PRB-910) - Transmitter (FTX-PWR+R series) - Software The temperature sensor probe is made from materials with high insulation resistance, allowing use in environments up to 38kV (three-phase). Additionally, there are options available for the probe's tip. The transmitter can continuously monitor the temperature of switchgear contacts, busbars, and other medium-voltage electrical equipment in real-time. One transmitter can connect 3 to 9 probes, enabling simultaneous measurement of temperatures at multiple points. It is also possible to connect multiple transmitters in series on a 35mm DIN rail.
