AS T-01 potential-free sensors are used for safe direct measurement of temperature on components such as busbars and busducts. They are installed by being screwed to the object with the use of an M10 nut and an M3 nut. The sensors should be installed at points exposed to higher temperature, i.e. at points where busbars are connected. The spatial location of the sensor does not affect the measurement. The values measured are transmitted with the use of POF 1/2.2 mm optical fibre which ensures full galvanic separation between the sensor and the measuring module. The sensors are equipped with a battery and their working time depends on the ambient temperature at which the battery operates.
