Product Specs

The WMS-20 series consist of three individual wind monitor stations. The WMS-21 is a microprocessor based wind alarm station. It sounds an alarm buzzer and controls the operation of two electrical circuits whenever wind speed reaches either of two independent setpoints. An LCD display provides a readout of the measured wind speed and is also used to set the value of the setpoints. Self-contained relays for each alarm point can be used to actuate external devices such as air samplers or sirens.

The WMS-22 series monitors wind speed and direction. Each parameter is converted into a 4 to 20mA signal for use by process controllers or monitoring systems. Two versions are offered, WMS-22A measures wind speed only, while the WMS-22B measures both wind speed and direction.

Is the WMS-23 UL certified?

Asked by: PhilipB
Thank you for your inquiry! The WMS-23 is not a UL certified product

Is the WMS-23 comparable with the VersaLog VL-WF-TC data logger?

Asked by: Daniel18
Thank you for your inquiry about the wind speed sensor. If the VL-WF-TC logger accepts a process or analog input, then, yes, it will.

I have an application that I would like to use a single anemometer with set wind speed & using relay contacts to send signal if speed is reached to 2 separate controllers. Is that possible with WMS-20 series product?

Asked by: JoeV
Thank you for your inquiry on this product. The WMS-21 wind station has dual setpoints to change states on a relay if the wind speed exceeds your desire set point.

How many times per second can the WMS-23 record wind speed and wind direction values to the data logger?

Asked by: Daniel18
Thank you for your inquiry! The output is a proportional 4-20 mA output and therefore the recording interval will depend on the specific data logger being used

What is the sampling frequency for this sensor? Is it capable of recording wind speed and direction values once ever second? (1Hz)

Asked by: Daniel18
Thank you for your inquiry for the wind speed sensor and it will record 1.25 MPH per 1 Hz.
