AAVTF-I Surface-mounted sensor, relative / absolute humidity, dew point, enthalpy (switchable) and temperature

The humidity sensor series HYGRASGARD~ KAVTF, AAVTF serves for the measurement of various cell quantities of humidity measurement technology. The relative humidity and temperature of the ambient air are measured. From these measured values, various keng magnitudes are calculated internally. For version x-U, two outputs 0...10V and for version x-I two outputs 4...20mA are available. Using DIP switches, the output quantities can be determined. Output 1 optionally gives relative humidity (% r.H.), absolute humidity (g/m3), mixing ratio (g/kg), dew point temperature (~C) or enthalpy (kj/kg) (without taking atmospheric pressure into account). Four different measurement ranges for ambient temperature (~C) can be set on output 2. The factory setting for output 1 is relative humidity 0...100% r.H., for output 2 temperature range 0...50°C. Due to the various configuration options, ~~one device can be used for a multitude of measurement and control tasks. The device can only be used in harmless gas-free, non-condensing air. Areas of application include, for example: medical, refrigeration, air conditioning and clean room technology. The probes are suitable for duct or wall mounting.
