Moisture sensor PCMini52 for climate control in the agricultural industry

In the field of food storage, the reliability of measurement and control equipment plays a major role. Here, a major European manufacturer of storage and climate control systems in the agricultural industry has chosen Michell Instruments' PCMini52 Relative Humidity and Temperature Transmitter to monitor ambient conditions in the systems it supplies. After extensive field testing, this sensor was chosen not only for its ruggedness, but also for its small size.
Climatic regulation for storage and transportation of fruits and vegetables requires cool but humid conditions. Ideally, the humidity should be around 80%, but not more than 95% relative humidity. If the environment is too dry, the fruit will dry out faster, and if it is too humid, it will rot faster.
However, an ideal atmosphere for fruits and vegetables is at the same time very demanding for the electronic monitoring instruments. The electronics used must therefore be well protected from moisture to ensure reliable, automatic operation of the ambient control over an extended period of time.
The fast response time of the PCMini52, less than 10 seconds, ensures a quick adaptation of the climate to the ideal conditions, so that there is no risk of food spoilage during storage.
The maintenance of the humidity and temperature sensor is very easy due to its very small dimensions, simplicity and robustness and can be performed by the end user or a service technician. It thus forms an easy-to-maintain integral part of the climatic control system.
