SITRANS TO500_Fiber Optic Temperature Measurement

The SITRANS TO500 multi-point temperature measurement system is designed to measure temperatures using a large number of sensors distributed across an extremely narrow fiber-optic probe. The system consists of the following components: a readout unit, a transmitter, and the measurement probe. Featuring four measurement probes, the SITRANS TO500 system can simultaneously handle up to 192 measurement points. This system is particularly well-suited for applications in confined spaces with low thermal mass, such as in tubular or tube-bundle reactors, or in capillary or microreactors.

Advantages

Fully utilize available space—thanks to its small probe diameter and rapid response, this device is ideal for monitoring dynamic processes.
Gapless – Featuring a total of 192 measurement points, it enables precise temperature detection and can be used for further process optimization.
Easy to install—can be rolled up for transport and conveniently inserted into the protective conduit.
Flexible and customizable to meet specific requirements—allowing the placement distribution of FBG sensors to be tailored precisely according to your needs.
Lean Solution – Measurement values are transmitted via the measurement probe, eliminating the need for additional cables.
Versatile functionality – suitable for measuring higher process temperatures and also applicable to low-temperature applications (depending on the probe type).
