Hygienic thermowells for temperature probes

July 2015 Temperature Measurement

Jumo has introduced a new range of hygienic thermowells for temperature probes to meet the safety demands of the food and pharmaceutical industry.

The function of hygienic thermowell fittings is to protect temperature sensors installed in industrial processes to allow maintenance and calibrations to be carried out without interruption to the plant running operations.

Jumo’s thermowells are manufactured using all standard process connections and include clamp, Varivent, CIP-compliant conical seal and aseptic screw connections according to DIN 11864-1. They are made of 316L stainless steel.

The probe tip of the thermowell has been reduced from 6 to 3,5 mm to improve the response time. The internal structure of the different temperature probes fulfils the same purpose. Here, a spring mounted measuring insert is used to allow only a minimum sized air space in the fully assembled temperature probe. As a result, an optimal response time of eight seconds can be reached in water.

Depending on the application, all standard probes in the food and ­pharmaceutical industry can be utilised. Temperature probes and thermowells are available with coordinating predefined standard lengths. This saves on storage costs and simplifies maintenance.
