Verified by manufacturer 18 days 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.
