KNOB ENCODER

An encoder is a sensor which turns a position into an electronic signal. There are two forms:

• Absolute encoders give an absolute position value.
• Incremental encoders count movement rather than position. With detection of a datum position and the use of a counter, an absolute position may be derived.

The position may be measured as either linear or angular position:

• A Linear encoder converts linear position to an electronic signal
• A Rotary encoder converts rotary position to an electronic signal

In foodservice equipment, a knob may be as simple as a push button or "palm button". A control knob is a rotary control used to provide input to a device when grasped by an operator and turned, so that the degree of rotation corresponds to the desired input . Such knobs are one of the most common components in restaurant equipment control systems and are used to modulate a wide variety of settings such as temperature, viscosity, speed and more.
