Описание:
Typical implementations of distance measurements use expensive rare-earth magnets. To lower overall system cost, this reference design walks through the implementation of industry’s first inductance-to-digital converters from TI for linear position sensing without the use of any expensive rare-earth magnets. Linear position sensing determines the position of a target that moves laterally across an inductive sensor that is generating a magnetic field. An inductance-to-digital converter (LDC), like the LDC1000 or LDC1101, senses inductance changes of an inductor that comes into proximity with a conductive target, such as a piece of metal. The LDC measures this inductance shift to provide information about the position of a conductive target over a sensor coil. The inductance shift is caused by eddy currents generated in the target due to the magnetic field of the sensor. These eddy currents generate a secondary magnetic field that opposes the sensor field, causing a shift in the observed inductance.

The TI Design TIDA-00475 demonstrates contactless, robust, cost effective, position sensing for variable speed trigger switches common in power and garden tools. The MSP430G2x53 microcontroller determines accurately the trigger position and generates the PWM signal to control motor speed and torque. This capacitive potentiometer enables by design high reliability, long life time, and robust operation in harsh environments. The contactless sensing is inherently neither effected by wear down nor moisture or dirt. Therefore it is an ideal replacement for sensitive resistive potentiometers in cost sensitive applications and resolves their reliability issues in harsh environments. The very low power standby operation of the system avoids discharge and damage to the battery pack in case of long term storage.
