The SITRANS TO500 has 4 channels which are evaluated simultaneously. The wavelength reflected at each sensor in the multipoint temperature measurement lance depends on the temperature, and this wavelength is output in the multi-point temperature transmitter. The temperature can be determined and displayed accurately at up to 48 sensors per channel. The positions of the sensors can be specified by the customer. This leads to a flexible and application-specific solution for the customer.

The measured temperatures are transferred to the control system via PROFIBUS DP. The parameters of the SITRANS TO500 are set via the integrated Ethernet interface.
