Verified by manufacturer 5 months ago
Compact wind and rain sensor with bracket mount.
Application
Suitable for installation externally. It is recommended to be installed at least two meters above the highest point on a building for accurate measurements. Can be connected directly to the control units WUC 102, and WCC 310/320 and all WSC 3xx/5xx which control smoke and ventilation units.
Description
The WLA 330 Wind/ Rain Sensor is a compact device designed to measure wind speed and detect rainfall. It includes an anemometer for wind speed measurement in meters per second (m/s) and a rain sensor surface that uses conductivity measurement on a heated surface to detect rain.
Features and benefits:
- Anemometer and conductivity sensor for wind and rain measuring.
- Adjustable sensitivity and delay settings.
- Adjustable wind trigger threshold, activation delay and drop out delay.
- Failure response via six-pole DIP switch with 'CLOSED' state for voltage failure events.
- Activated by change-over-contact.
