All models are also available with signal outputs for speed, threshold and blockage. An alarm signal will be sent when the speed of the fan motor slows down, enabling predictive and preventive maintenance, resulting in higher system availability. Two variants are possible: the output of a 3rd wire signal rotation detector function (also called locked signal or alarm signal) and a signal frequency generator function (also called speed signal).
Customer-specific solutions can be developed, including cable assembly and waterproof or moisture-resistant protective coatings. The versions with dust and waterproof properties make the fans suitable for applications in harsh environments. ▪ ds
