WS-15A Display

Product code: WS15ADISP

£ inc VAT

Add Magnetic Mounting Feet @ £ for set

The WS-15A offers a cost effective solution for wind & weather display and monitoring when using a wide range of meteorological sensors.

Compatible with the WindSonic, WindSonic M  & WindObserver ultrasonic wind sensors and the MetPak weather station, as well as other sensors outputting NMEA wind data.

It has an easy to read 40 character display which shows wind speed in a choice of measurement units and wind direction in degrees, as a wind arrow and as cardinal points.

There is a wind speed alarm output and sensor / system status display.

When connected to a MetPak weather station, additional displays of temperature, pressure, relative humidity and dew point are available.

When connected to a WindObserver sensor, additional displays of sonic temperature and speed of sound are available.

The five tactile buttons with displayed prompts make operation and configuration of the system simple. Adjustable settings include sensor alignment, alarm, wind speed units, pressure calibration, sensor input, display contrast and backlight. An adjustment lock is provided to avoid inadvertent adjustment of the alarm and sensor settings.

In a system several WS-15A display units can be connected to one sensor or daisy chained using the RS232 output.

Compatible with

WindSonic range of wind sensors
WindSonic M wind sensor
MetPak weather station
MetPak RG weather station with precipitation
• WindObserver sensor
• NMEA sensors

Wind Speed Alarm

The wind speed alarm is configurable as either a high or a low alarm and to avoid false alarm events, there are adjustable hold off and hold on times.
Take a look at our compatible alarm units.

RS232 Output

An RS232 output is provided for connecting to a SpaceLogger W10 (WindLogger), SpaceLogger W8 Wireless or other data logger, computer or radio modem.

When using the RS422/RS485 input, the display can often eliminate the need for a separate RS422/RS485 to RS232 converter. There is also an optically isolated input for when extra isolation of the sensor is required.

Radio Modem Option

The WS-15A display can be used as part of a remote sensor system using Digi Xstream-PKG radio modem to transmit and receive data.  When using these radios the WS-15A will display a signal strength bar to help with optimal positioning of the antenna.
