Sensors delivering a
0–10 V signal
A 0–10 V sensor is selected by setting Type to 0–10 V. This type of sensor can be
used for measuring:
• Sun intensity
• Wind velocity
• Water flow
• Energy
• “Other”.
When Type is set to 0–10V, 2 more parameters can be set: Amplific. and Offset.
The function of these is explained in the following.
Amplification, Offset
The sensor applies a voltage in the range 0–10 V to the controller’s sensor input.
This voltage must be converted into the correct value. The parameters Amplific.
(amplification) and Offset are used to perform this calculation, as illustrated in
Figure 19.
Offset
Value [m/s, l/h, ...]
Value = Amplification * Input + Offset
