Temperature Chain TC-03

Temperature Chain TC-03


The fiber optic Temperature Chain TC-03 is a compact, fiber sized cable containing several temperature sensors in series. Each temperature sensor is contained in a glass capillary tube of small size. All sensors are in the same optical line and the Chain has a connector at one or both ends in order to make series configurations possible. The Temperature Chain can be entirely configured according to the customer needs i.e. the number of temperature sensors and the intermediate sensor distances can be specified.
