Safe monitoring of under speed

October 2016 IS & Ex

The speed monitor DU110S from ifm electronic has been developed for safety-related minimum speed monitoring required, for example, for slip or V-belt monitoring.

An application example is the industrial thermo processing equipment according to EN 746-2. In this case, safety-related monitoring of the air exchange is required. To do so, monitoring is done via rotational speed monitoring of the fans.

The speed monitor is certified to EN 62061 / SIL 3 and EN ISO 13849-1 cat, 4 / PL e even though non-safety related sensors are used as pulse pick-ups.

Besides the 2-pole safety relay, transistor outputs can also be used for status and error indication. Automatic or manual reset of under speed is possible and can be set via wire links.

The safety speed monitor operates at extreme ambient temperatures down to -40°C.
