Humidity sensors

Humidity sensors: Functionality

Water vapour, also known as humidity or moisture, can have a decisive influence on the working performance of electrical systems and on human well-being and health. For example, 65% air humidity indoors leads to the formation of mould spores that are harmful to health and material.

To control the humidity, it is recommended to use so-called humidity sensors, which measure the relative humidity and convert it into a standardised signal.

Frequently, humidity sensors can also detect temperature, as this is closely related to humidity. The greater the amount of water vapor, the higher the perceived temperature.

These combination devices, which combine the function of temperature and humidity sensors, therefore play an essential role in room air conditioning and heating, for example. By determining dew point and temperature, the sensors can also help to avoid condensation within electronic components. Condensed water always forms when the temperature falls below the dew point.

Where are humidity sensors utilised?

Humidity sensors are used in the following industries, for example:

• Building technology
• Air conditioning technology
• Food industry
• Agriculture
• Automotive engineering
• Medical technology

Temperature and humidity sensors from stock at Automation24

At Automation24 you can purchase in the category Process sensors, outdoor humidity sensors from the ARFT series and room humidity sensors from the RFFT family from the measurement technology specialist TiTEC at a fair price-performance ratio.

All humidity sensors in the sensor systems range are capacitive combination sensors that measure relative humidity and temperature via an internal sensor and convert them into an analogue signal. The external sensor type ARFT is very stable over the long term and does not need to be recalibrated.

Incidentally, you can counteract excessively high humidity within control cabinets from the outset. Simply rely on the use of filter fans, which are also available from Automation24.

Do you only want to measure the temperature and not the humidity? Then pure temperature sensors are sufficient for you. These can also be found in the Automation24 range.

Order temperature and humidity sensors from Automation24 now and protect yourself and your electronic components from the effects of too much water vapour! If you have any further questions, we will be happy to help you. Just contact us!
