Humidity measuring range
A sensor or (measuring) probe is a technical component which, in addition to certain physical or chemical properties (e.g.: Thermal radiation, temperature, humidity, pressure, alternating sound pressure, sound, brightness, magnetism, acceleration, force), it can also detect the material properties of its environment qualitatively or quantitatively as a measurand. Due to high dynamics and the great influence of water vapor on all kinds of materials and objects, there are different sensor principles to determine humidity.
HYT sensors are used to measure relative humidity and temperature. The measured data are transmitted via I²C bus. Our HYT humidity sensors have a wide measuring range of 0...100 % RH and -40...+125 °C. This results in a wide range of applications in various fields of use.
Capacitive humidity sensors
The capacitive humidity sensors from B+B are suitable for a wide range of applications. The low price, mechanical robustness, good linearity and resistance to dew formation should be emphasized.
Resistive dew sensors
The resistive dew sensors for the detection of incipient dew formation and condensation have an exponentially increasing and resistive characteristic curve, which ensures simple signal evaluation and stable switching behavior at the dew formation limit. The large area allows optimized thermal contacting to detect surface moisture on cooled objects. For this purpose, the dew sensors can be bonded to metallic materials, for example. Applications are building control systems, cooling ceiling switches, air conditioning systems, moisture protection in switch cabinets and electrical systems, condensate detection on exterior walls, ventilation control in sanitary rooms, leakage monitors for waterproof housings, brown goods, camcorders, cameras and many other objects that need to be protected against dew.
Electrolytic humidity sensors
Another sensor from the humidity sensor group is an electrolytic polymer sensor for measuring relative humidity. The humidity sensor converts the relative humidity value into an impedance that is measured electronically. Typical applications are climate monitoring, household appliances, office and communication equipment, building management systems, refrigeration and air conditioning, humidifiers and air dryers.
