WIND MONITOR STATIONS
With Dry Contact Alarm or Analog Outputs
WMS Series
The WMS-21 dual setpoint wind
alarm is a microprocessor-based
wind alarm system. It features
an audible alarm and controls
two relays whenever wind speed
reaches either of two independent
setpoints. An LCD displays the
current and wind speeds.
The WMS-23S monitors wind
speed, converting 0 to 100 mph
wind velocity to a proportional
4 to 20 mA signal for use by process
controllers or monitoring systems.
The WMS-23 monitors wind speed
and direction, with a second
4 to 20 mA signal corresponding
to 0 to 360°. The three cup
anemometer (and wind vane) is
constructed of UV resistant ABS
plastic and anodized aluminum,
while the electronics are housed
in a gasketed wall mount NEMA
enclosure.
