Also for Atex applications

The speed monitoring of rotating plant components is necessary in many applications to avoid expensive failures. This can be realized particularly easily with the new speed monitor from IFM – even in hazardous areas.

The new speed monitors from IFM work with an inductive proximity switch that detects a damping element on a rotating plant part. The damping element can be a screw on a shaft, for example. In order to be able to monitor speeds using this method, the evaluation electronics are directly integrated into the compact speed monitors. This makes speed monitoring very simple and cost-effective. The speed monitors, which are housed in a robust M18 stainless steel housing, are available for non-flush (DI6004) and flush (DI6005) installation. Both models are also available in a version for Atex applications (DI604A and DI605A, respectively). Parameterization is very easy thanks to the integrated IO-Link interface. Alternatively, the settings can also be made directly on the sensor housing via an actuating ring.

The speed monitors can be operated in different modes. For example, a speed threshold can be defined, below which the output switches. Alternatively, a window mode with two switching points is also possible. In addition to the switching output, the speed monitor also offers a pulse output. Additional information, for example the current speed or an operating hours counter, can be read out via IO-Link. Applications can be found wherever rotating plant components need to be monitored. Typical examples are belt drives in conveyor systems or screw conveyors for bulk materials. In the case of flammable bulk solids, the Atex versions of the speed monitor are usually used.
