Temperature is a fundamental physical parameter that influences nearly all chemical, biological, and physical processes in aqueous systems. It directly affects the solubility of gases (such as oxygen), the speed of chemical reactions, and the activity and growth of biological organisms.
In water analysis, temperature is often measured alongside other parameters because it significantly impacts values such as pH, conductivity, and dissolved oxygen. Accurate temperature measurement is therefore essential for precise monitoring and control of a wide range of processes.
JUMO temperature sensors are used in numerous applications, including:
-
Drinking and wastewater treatment: Monitoring temperature to optimize precipitation, disinfection, and clarification processes.
-
Food and beverage industry: Temperature control during CIP processes, pasteurization, and product flow.
-
Pharmaceutical industry: Maintaining temperature-critical production steps and hygiene standards.
-
Aquaculture and fish farming: Ensuring appropriate water temperatures for various species.
-

It offers precise temperature measurement in both liquid and gaseous media. The installation design of this thermometer ensures reliable tightness, even under extreme conditions of negative and positive pressure. The possible applications range from dry to humid environments and, depending on the version, enable precise temperature measurement in the range from -50 to +400 °C. The connection cable of this screw-in resistance thermometer is available in various materials, including PVC, silicone, PTFE and metal braiding. This variety makes it possible to select the right variant for your application. The transition of the connecting cable is strain-relieved and an optional bend protection can be fitted to ensure the longevity of the connection. The measuring insert is equipped as standard with a Pt 100 temperature insert in accordance with DIN EN 60 751, class B in a two-wire circuit. Optionally, the measuring insert can also be selected with Pt 500 or Pt 1000. In addition, the connection can be made in either three- or four-wire circuits to meet individual requirements.

The uncomplicated mounting with tensioning straps or hose clamps eliminates the need for mechanical processing of the measuring point. Indirect temperature measurement guarantees interference-free temperature measurement, unaffected by flow, pressure or chemical influences. Due to the low thermal mass of the measurement object, the influence is kept to a minimum. Heat-conducting paste is available as an option to optimise heat transfer. Large temperature differences between the measured medium and the environment are directly reflected in the measurement; additional insulation is recommended here. A Pt100 temperature sensor in accordance with DIN EN 60751 Class B is installed as standard in a two-wire circuit, but variants with Pt500, Pt1000 are also possible.
