4.7.2.2 Crane Application
In the crane application, WMT700 can provide wind speed value and to drive alarm signals
with 2 mA output channels. The WMT00 alarm output signal can be connected to external
audible or visible devices to trigger wind speed alarm for user-defined limits.
Two analog channels are required for this application:
• Channel 1 provides the wind speed value
• Channel 2 provides the alarm signal
Figure 27 Analog Output for Wind Speed and Wind Speed Alarm
The wind speed value can be scaled according to the sensor’s measurement range. The
alarm signal operates with on/o-mode. The alarm threshold can be adjusted. The following
figure shows the relation of outputs.
