The GEL 247 is a 1 or 2 channel application approved speed sensor based on magnetic measurement principle which has maintenance- and wear-free operation due to a contactless measurement of rotation.
The speed sensor has scans measuring scales made of ferromagnetic materials, e.g. toothed wheels and has a side measuring range for safe detection of slow rotation without pulse loss and for high-speed rotation.
It’s two channels shifted by 90° provide the direction of rotation and all contained in robust and compact stainless steel housing suitable for harsh application.
