The measuring wheel MR 10 serves to continuously record the belt speed in belt conveyors and is used in combination with the MTS built-in belt scales.
The measuring wheel is either directly installed on the support bars of the belt scale or on the cross-bar of the belt scale construction.
Themeasuring wheel MR 10 consists of a robust, ball bearing mounted friction wheel with integrated perforated disc, a sensor as well as a wheel bar and bracket of the measuring wheel. The friction wheel made of polyamide has a very abrasion-proof polyurethane running surface and is supported by two high-quality deep groove ball bearing on the wheel bar. The stainless steel wheel bar absorbs the sensor and is movably mounted on the bracket via a solid shaft.
The MR 10 is available in three dimensions: with a wheel diameter of 200 mm, alternatively 160 mm or 250 mm.
Other features of the measuring wheel MR 10:
The measuring wheel runs on the lower belt and records the current belt speed. On the basis of its own weight, the measuring wheel is located frictionally engaged on the belt and is driven by the belt movement. As a result, the rotatio speed of the measuring wheel is exactly equivalent to the belt speed.
The inductive proximity switch measures the running speed of the belt via pulses arising from the number of holes in the perforated disc, the wheel diameter and the current belt speed. An incremental rotary encoder is used for legal-for-trade applications. The generated voltage pulse (frequency) is converted in a speed value (m/s) via the control unit.
