SITRANS TS300 – Hygienic Temperature Sensor

Why SITRANS TS300?

By mounting SITRANS TS300 to the outside of pipes without welding, the clamp-on design keeps lines unobstructed and allows fast recalibration. Achieve in-line accuracy without breaking the process seal. EHEDG-compliant construction minimizes disturbances and reduces validation. Alternatively, a modular solution is available to install the sensor directly in the process tube if clamp-on does not fit.

Key benefits

Accelerate hygienic installation

The clamp-on design allows for quick, welding-free mounting directly onto your pipes. This eliminates the need for process interruptions and prevents dead spaces, helping to ensure a perfectly hygienic, unobstructed line.

Lower total cost of ownership

Thanks to a modular assembly and replaceable measuring inserts, maintenance and recalibration are fast and straightforward. Service the sensor without breaking the process seal, significantly reducing downtime and costs.

Improve measurement confidence

The clamp-on version features a silver measuring element pressed against the pipe by a spring. This enables optimal thermal contact and a fast 4-second response time for highly accurate, reproducible temperature monitoring.
