Food Processors and Mixers Use Current Sensing Relays

Food Processors use current sensing Reed Relays to trigger an output when the coil current exceeds a set, designed-in point. Reed Relays can also be designed to switch multiple circuits. Such Reed Relays are usually designed with minimal turns of the coil using Copper wire diameter go higher thicknesses which is more than the winding used on standard signal switching relays.

Mixers, food processors and grinders require an over-current protection limit which cuts off the power to the motor whenever the grinding blades or mechanical parts get obstructed physically, to protect the motor winding from getting burned.

Reed switch based current sensing relays are available in a wide range of configurations such as normally open, normally closed and capable of turning on or off multiple circuits when the set current is reached. A simple Magnet Sensors and a magnet is also used in Food Processors to check if the grinding jar has been locked in fully. This helps the motor mechanism engage well with the jar for efficient operation.

The design of current baed Reed Relays is critical and several parameters of the basic reed switch such as lead diameter and blade flexibility affect switching point. Current sensing Reed Relays are also designed in with Resistor-Capacitor arrays to protect the reed switch contact from working off the motor of Food Processors.
