SITRANS TO500

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 therefore be processed at the same time by a SITRANS TO500. 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)
