Inductive Position and Speed Sensors

Dsp Based Read out System for Contactless High–frequency Inductive Position Sensors

This paper presents a precise and low cost absolute position inductive measurement system for rough industrial environments. This transducer works on similar principles as contactless resolvers but consists of a rectangular antenna PCB, a passive LC resonance target and a signal processing unit. The read out electronics utilize undersampling to demodulate the transducer in–phase and quadrature ...

Microcontroller-based interface circuit for inductive sensors

This work proposes a fully-digital interface circuit for the measurement of inductive sensors using a low-cost microcontroller (μC) and without any intermediate active circuit. Apart from the μC and the sensor, the circuit just requires an external resistor and a reference inductance so that two RL circuits with a high-pass filter (HPF) topology are formed. The μC appropriately excites such RL ...

High Speed CMOS Image Sensors

This paper gives an overview of high speed CMOS image sensor types and markets in which these can be used. The sensors presented in this paper are sensors designed for use in a general purpose, high end or custom high speed cameras. Such cameras can be used for applications like scientific research, crash tests, high speed scanning, machine vision and military research; all requiring high frame...

An Inductive Pick-up for Beam Position and Current Measurements

D D The fractional part of the betatron tune for a circular accelerator can be measured by observing beam oscillations on a position pick-up. In frequency domain the betatron frequency is seen as sidebands on either side of the revolution harmonics. Usually beam signal pulses from the pick-up are very short with respect to the revolution period, resulting in a broadband spectrum. Classical tune...
