Torque overload clutch signals wirelessly
24 June 2010
The new EAS-Sensor safety clutch with integrated signal transmitter from Mayr has a fully integrated limit switch. On detection of an overload condition, the device transmits a signal wirelessly to a base station connected to the machine controller. The EAS-Sensor is factory adjusted and there is no need for subsequent assembly and adjustment. Overload sensing is fully reliable; external factors such as vibration or axial offset of the clutch, which for example may result from thermal expansion of the shaft, do not impair operational reliability.
The transmitter, including its power supply, is entirely contained in the torque adjustment nut of the safety clutch. It reports the operating state of the clutch at regular, short intervals, along with information on the supply voltage level. If the supply voltage drops, a warning signal is triggered to prompt a battery change - an action that does not require the clutch to be dismounted.
The new EAS-Sensor is superior to conventional safety clutches with external limit switches that are subject to movement, poor adjustment, vibration and thermal effects.
