Control cabinets in the production
Electricity and humidity have to be strictly separated from one another– this also applies to control cabinets in automized production systems. However, particularly in processes under hygienic conditions such as in the food industry humidity can enter the control cabinet due to the frequent cleaning processes. Possible causes are PG fittings, air slits, defective sealings or doors which have not been closed properly. If the humidity inside remains undetected this can lead to corrosion.  A housing which is subject to leakage can no longer, or insufficiently protect the electronic components inside from external influences such as water, dust or dirt. Also the electronics can be considerably damaged when subject to corrosion and condense water, leading to unplanned, cost-intensive down-time.

Overheating due to lack of heat removal can also cause damage and subsequent down-time. Using an air humidity sensor it is possible to continually monitor the conditions inside the control cabinet. Maintenance personnel can react before increasing heat or humidity lead to loss of production.

Securing performance in server rooms
In server rooms you find a large number of powerful electronics. The high computational intensity creates heat. If this heat is not removed properly the server can overheat. This could lead to a drop in performance. However, the worst case could be lasting damage to the electronics – leading to server failure. A possible cause is excessive humidity. It is therefore for this value to be monitored and regulated.

The air humidty sensor monitors the temperature and humidity values in the server room.  And ensures that all incoming data can continue to be processed reliably.

Protecting outdoor machines and systems

Outdoor systems and dispensing machines
You will also find control cabinets in machines which are subject to outdoor conditions: Ticket machines, snack dispensers, radar systems or ATMs are subject to natural deviations in temperature and rain. The air humidity sensor transfers the relevant data – temperature and air humidity – and prevents the electronics from overheating or short circuits caused by humidity by shutting the system down.

Switch-on protection on wind turbines
Wind turbines are subject to heavily fluctuating conditions. If the system is not in operation it cools downs to -40 °C. To prevent damage to the electronics caused by condensation, a heating system is switched on to bring the electronics up to operating temperature. The heating continues to reduce the condensation until the air humidity sensor detects when the ideal temperature has been reached so that the system can restart. This prevents short-circuiting of the high voltage system if it is switched on too early.

Ensuring constant process and product quality

Production, processing and storage of climatic sensitive products
In some manufacturing processes it is important to keep the temperature and the air humidity at a constant level to ensure product quality and prevent costly scrap. One example is the manufacture of paper. Paper is hydroscopic which means that it absorbs moisture from humid air and if the ambient air is too dry it releases it.  Fluctuating environmental conditions during the production of paper mean that the paper can be more difficult to write on or the quality of the tear-resistance suffers. The air humidity sensor measures the temperature and air humidity in the direct vicinity of the production line. If there are deviations to the ideal values then it is possible to react quickly and maintain the paper quality.

The air humidity sensor is also suitable for use in the further processing of paper such as printing works or storage facilities such as archives or libraries.

Exact detection of environmental conditions of test-rigs
Text-rigs are used to test products under constant conditions or under deliberately changed conditions. So that the results are comparable, reproducable and plausible it is necessary to have an exact documentation of all data. The air humidity sensor provides the relevant air humidity and temperature values which have occurred during the test procedures.
