Temperature probe TP-DN

The TP-DN thermal probe is a primary measuring device designed for direct contact temperature measurement of grain products in elevator silos, floor storage facilities for husks and meal, and metal containers (with flat or conical bottoms). The TP-DN type thermal probe is developed to minimize the load on the roof of metal silos.

The construction of the TP-DN thermal probe utilizes a tube made of stainless steel, inside of which a ribbon with DS18B20 digital temperature sensors from Maxim Integrated is placed. The thermal probe can contain from 1 to 24 sensors depending on its length and application area.

Reducing the diameter of the thermal probe to 8-9mm, combined with a smooth surface, has allowed minimizing the loads on the silo roof to minimal values.

The construction of the TP-DN thermal probe is designed to minimize bending and twisting loads on the probe itself and consequently on the silo roof. A mounting loop is provided in the upper assembly for attaching the thermal probe to the silo roof. A mounting hole is provided in the lower assembly to secure the bottom end of the thermal probe and thus prevent it from deviating from the vertical position. Technical solutions are applied in the design of the assemblies to seal the cavity with the sensors, providing a protection rating of at least IP65 against external influences.
