Wind Monitor Stations
with Dry Contact Alarm or Analog Outputs
The WMS-20 Series consist of
3 individual wind monitor stations.
The WMS-21 is a microprocessorbased wind alarm station. It sounds
an alarm buzzer and controls the
operation of 2 electrical circuits
whenever wind speed reaches
either of 2 independent setpoints.
An LCD display provides a readout
of the measured wind speed and is
also used to set the value of the
setpoints which are stored in nonvolatile memory. Self-contained
relays for each alarm point can be
used to actuate external devices
such as air samplers or sirens.
The WMS-23 Series monitors
wind speed and direction. Two
versions are offered; WMS-23S
measures wind speed only, while
the WMS-23 measures both wind
speed and direction. Each
parameter is converted into a
4 to 20 mA signal for use by
process controllers or monitoring
systems.
WMS-23, wind speed
and direction module,
$730, shown smaller
than actual size.
WMS-23S, wind speed and direction
module, $675, shown smaller than
actual size.
