He shows how an LVDT or linear variable displacement transducer works and how it is wound around an air-core. He also designs a differential detector circuit using a precision op-amp. He also provides two LTspice simulations, which show the drawbacks of using a simple diode vs. a precision rectifier so you can try it out on your own.</p> <h3 id="mcetoc_1h52g7p090">Watch the Video:</h3> <p><a href="https://www.youtube.com/watch?v=_lJ9NcN7fO4">www.youtube.com/watch</a></p> <h3 id="mcetoc_1h52gbtfu1">Bonus Content:</h3> <ul> <li><a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-06-71/BasicDetector-Derek.asc.zip" data-e14adj="t">LTspice File</a></li> </ul> <div style="background:#ffffff;border:1px solid #dadada;margin:0;padding:14px 16px 16px 18px;vertical-align:top;"> <div style="display:inline-block;float:left;padding:0px 25px 8px 0px;"><a href="/challengesprojects/element14-presents/" data-e14adj="t"><img alt="element14 presents" src="/e14/assets/legacy/2021/e14PDCtoDaylight2021.png" /></a></div> <div style="display:inline-block;vertical-align:top;width:70%;"> <p style="margin:0;"><span><a class="jivecontainerTT-hover-container jive-link-community-small" href="/challengesprojects/element14-presents/" data-e14adj="t">element14 presents</a></span>&nbsp; <strong>|</strong> <a class="jive-link-wiki-small" href="/challengesprojects/element14-presents/vcp-program/w/documents/4139/vcp-biography-derek" data-e14adj="t">About Derek</a>&nbsp;&nbsp;<strong>|</strong>&nbsp; <a class="jivecontainerTT-hover-container jive-link-community-small" href="/challenges-projects/element14-presents/dc-to-daylight/" data-e14adj="t">DC to Daylight</a></p> <p style="margin:0;"></p> </div> </div><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: lvdt, mutual inductance, lock-in amplifier, preconditioner, precision rectifier lvdt detector circuit, linear variable differential transformer</div> https://community.element14.com/challenges-projects/element14-presents/dc-to-daylight/w/documents/28265/how-to-build-a-linear-variable-differential-transformer-motion-sensor-and-detector----dc-to-daylight-29/revision/1Tue, 11 Jul 2023 13:03:21 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:8e7b3f35-d6d4-4cdf-b7da-15d637fdbb5ftariq.ahmadhttps://community.element14.com/challenges-projects/element14-presents/dc-to-daylight/w/documents/28265/how-to-build-a-linear-variable-differential-transformer-motion-sensor-and-detector----dc-to-daylight-29#commentsRevision 1 posted to Documents by tariq.ahmad on 7/11/2023 1:03:21 PM<br /> <p>In this application-based episode, Derek shows how to build a sensor which measures linear motion using mutual inductance.
