Tsens

Product Features

The Rugged Monitoring Tsens probes have been designed and built so they can be incorporated into your transformers to give precise results (direct measurements of temperature). The sensing technology is based on the proven zero-drift GaAs technology. They are completely built using first quality materials, all with very high dielectric strength, so your transformers can benefit from accurate temperature readings, which is essential to a good knowledge of transformer aging rate. During factory heat run tests, these probes will give both transformer manufacturer and operator invaluable information regarding the transformer's expected MVA performance. The patented tip construction makes them extremely robust and easy to install in radial spacers or other pressboard material (such as for temperature measurements in cores or other transformer components). This tip, along with a 200  Ø fiber offers the highest probe pulling force in the industry. The spiral-wrap cable is specially constructed to allow complete oil penetration so you can be assured that no air can be present. All materials used in the probe construction are compatible with high-temperature kerosene desorption processes.
