Adjustment test bench for room sensors
Low flow measurement, air conditioning
Room sensors should measure the ambient conditions in rooms such as temperature, relative humidity, CO2 values, smells etc. in order to ensure comfort in a room. Obtaining reproducible measurements of the room temperature is extremely challenging as various effects influence the temperature measurement. With the calibration test bench, precise air flows can be set despite low flow velocities. The solution concept therefore consists of a channel in the channel system. In the inner channel (orange) the air flow, i.e. the flow profile and the flow velocity are precisely controlled at the room sensor. The outer channel (blue) is responsible for conditioning the inner channel. Different flow velocities under different ambient conditions can thus be realized on the test item.
