What is and what is used for
The air humidity sensor consists of a membrane of hygroscopic material that forms the dielectric of a capacitor so that the water molecules in the air are absorbed by the dielectric, thus causing a change in the capacitor’s capacity, due to the humidity, to which a change in the oscillation frequency of an electrical circuit connected to a sensor corresponds, which in turn transforms it into a change in direct voltage. The probe produces a signal/noise ratio.Construction
The SHN transducer is a multiple sensor containing the transducers for measuring air temperature and humidity. The instrument consists of a “PT100 CI.A” thermistor according to the DIN 43760 standards to measure air temperature and a capacitive type of sensor to measure the relative humidity.Main features
- Protection devices: the sensor is equipped with fast semiconductor electronic devices for protection from electric discharges.
- Easy maintenance: the benefits that our thermohygrometric sensor offers are not limited to precision, but also include simple and quick maintenance due to the engineering of the sensor that simplifies the phases. The only preventive activity consists of cleaning the sensor screen (once a year) in order to ensure its full functioning.
- Sturdy and reliable construction: lastly makes it an instrument with a long lifetime, which safeguards the customer’s investment. The instrument does not drift due to aging and requires no periodic calibrations.
- Components that can be added or be built into the product: none.
