Sensor combination in 20cm height for close to ground measurement of air temperature / relative humidity

• parallel determination of air temperature and relative humidity
• low-maintenance software calibration
• laser-trimmed humidity sensor
• further minimization of the temperature dependence of humidity sensors by complex software linearization
• only in connection with UNIKLIMA^®
• bronze sinter cap protects humidity sensor against harmful environmental influences such as dust and aerosols
• sensors also separate available as air temperature sensor LT1 and as humidity sensor RLF

• combination humidity / temperature   10105
• LT1 air temperature sensor (separate)  10103
• RLF1 relative humidity sensor (separate)  10104
• Radiation protection with spike 10131

The sensor combination air temperature / relative humidity is used  for the measurement of the air temperature and the relative humidity in connection with UNIKLIMA^® in 20cm height above ground. According to standard, it is supplied  with an optionally available radiation protection with spike.

The air temperature sensor and the humidity sensor can also be supplied individually in each case.

The air temperature sensor consists of a temperature-dependent silicon regulated current source, whereby there is no influence on the measuring signal / accuracy by the sensor line resistance / conduit length. Of course, on customer's request, we also supply  the conventional PT100 .

The humidity sensor is structured as a planar multi-layer sensor and is equipped with a complex software temperature compensation.
