SITRANS TO500

Fiber Optic Temperature Measurement

The SITRANS TO500 multipoint measuring system is used for evaluating a large number of temperature measuring sensors arranged on a very narrow fiber-optic measuring lance. The system consists of the following components: a read-out unit, the transmitter, and the measuring lance,. With up to four measuring probes, 192 measuring points can be processed at the same time. The system is particularly suitable for applications in constrained spaces with a low thermal mass, i.e.  in tube and tube bundle reactors or in capillary or microreactors.

Benefits

  • Make the most of the available space - Small diameter of the measuring lance enables fast response times for dynamic process monitoring 
  • Gap-free - With a total of 192 measuring points temperatures are accurately detected and used for further process optimization
  • Simple installation - Lance is delivered coiled on a capstan and can hence easily be inserted into the protective tube 
  • Flexible and customer-specific - Positioning of the FBGs according to your individual needs
  • Lean solution - No additional cabling required as the transfer of the measured values is handled via the measuring probe
  • Versatile - Suitable for high process temperatures as well cryogenic applications (depending on type of lance)
