Further information about this JUMO version

The version with two Pt100 sensors is particularly practical. This is especially useful when two measuring signals are required or when additional protection of the temperature measurement is desired. As a result, this version is well suited for applications where measured values need to be recorded, monitored, or processed in parallel.

The continuous thermowell ensures a robust design. At the same time, the screw-in mounting enables secure integration into the measuring point. This is an advantage in applications where temperatures must be monitored continuously and the installation situation must remain reliably sealed even under negative or positive pressure.

The Form J connection head supports a clean and protected electrical connection. Together with the Pt100 sensor according to DIN EN 60751 in Class B, this results in a classic solution for many common measuring tasks in industrial temperature measurement technology. The two-wire circuit makes this version a proven option for practical applications.

Typical application areas

  • Air conditioning and refrigeration technology
  • Heating engineering, furnace engineering, and apparatus engineering
  • Pipeline and tank construction
  • Mechanical and plant engineering

JUMO order code:

A JUMO order code uniquely identifies a specific measuring instrument or component based on its configuration.
