8 Measurement Output
The factory default setting for the transmission of measurements is UMB binary protocol.
You can find an example of a measurement request for the various protocols and a complete
summary of the list of channels in the Appendix.
8.1 Virtual Air Temperature
Sampling rate 1 – 10 seconds
Generation of average value 1 – 60 measurements
Units °C; °F
Request channels:
Note: In order to transmit the current measurement value the second measurement values are
averaged over the sampling rate.
8.2 Heating Temperature
Sampling rate 1 – 10 seconds
Generation of average value 1 – 60 measurements
Units °C; °F
Request channels:
Heating temperature bottom
Heating temperature bottom
8.3 Air Pressure
Sampling rate 10 seconds
Generation of average value 20 measurements
Units hPa
Request channels:
Note: For pressure measurement a hardware version equal or greater than 3.0 and a software
version equal or greater than 1.6 is necessary!
8.3.1 Air Density
Sampling rate 10 seconds
Unit kg/m³
Request channell:
Note: Relative humidity is required for the calculation of air density. As Ventus-UMB does not
include a humidity sensor, an adjustable standard value is applied. With UMB-ConfigTool.NET
this value can be adapted to the conditions at the location of installation (see Chapter 12.2.8) .
Factory setting is 75% rel. humidity.
