R220 Temperature/Humidity Transducers
These compact and lightweight transducers are dry and wet
bulbs type temperature/humidity sensors with ventilating
function.
The units employ two platinum resistance thermometers as
temperature detecting elements for dry and wet bulbs, and
consist of a ventilating unit, detecting elements, and a water
tank for wet bulb, and others. Since the water tank is
detachable and a terminal board is exposed when tilting the
units forward under the wallmount condition, the wiring,
check and maintenance are very easy.
