Kaiser Nienhaus 336100 Limit switch

This limit switch for monitoring wind is universally used. In conjunction with the wind sensor, wind strengths from 2 to 8 can be captured. Exceeding the set wind strength is immediately indicated by an LED. After the lapse of the set switch-on delay, the relay contact is switched. Depending on the setting, the relay either remains active for only 2 seconds, or it will be permanently connected during the storm phase. The adjustable delay time thereby provides, even in small drops below the threshold, a continuously stable switching status.
