Not long after the rule first went into effect, Earnhardt said he “probably couldn’t have passed all was one of the first to use the Temposonics/Techmor sensor. Arguably, the most popular driver of our day, Dale Earnhardt Jr.

Techmor adapts the magnetostrictive sensing technology specifically developed for mobile hydraulic applications by Temposonics with a carbon fiber and aluminum housing to maintain a lightweight yet resistant package forĭrivers and their teams quickly adopted the new technology, and magnetostrictive sensors are now pervasive throughout NASCAR. “The MS sensor at the heart of the PS-1 is an extremely accurate instrument (down to 0.1 mm) that is also tremendously rugged,” said Todd Mory, PresidentĪnd Founder of Techmor, Inc. The solution: the PS-1, a Temposonics ® MH-Series MS position sensor adapted by Techmor. The team needed a reliable and accurate position sensor that was both lightweight and rugged enough to withstand

They seeked for a fully encapsulated, non-contact solution for track bar adjustments. ,Īn advanced instrumentation specialist for auto racing.

Hendrick Motorsport team approached Techmor, Inc. Sensor can accumulate dirt, which can result in the sensor sticking or jamming. Because the wire is exposed to the elements, the A string pot mechanically measures the distance a wire is pulled from the sensor body. When the new rule was introduced in 2015, some teams tried string pot technology to help set the track bar position. Prior to 2015, alterations to the track bar were only permitted on pit row where crews spent valuable seconds making these adjustments, time that could directly affect position in the race. Track bar adjustments alter the position of the rear axle, making the handling “tighter” or “looser.” An important rule change came in 2015, when NASCAR allowed drivers to adjust the track bar from inside the cabin Each year NASCAR releases a new set of rules by which each team must abide. What is NASCAR today? It is 20 competing teams with carsĪpproaching (and surpassing) speeds of 200 miles per hour.

Rooted in bootlegging illegal whiskey during prohibition, the inception of the National Association for Stock Car Auto Racing, better known as NASCAR, is steeped in nearly clichéd history.
