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. MOST POPULAR MODELS HIGHLIGHTED! WMS Series Starts at $675
