The Matrix: Linear Position Sensing

“You take the blue pill, the story ends. You wake up in your bed and believe
whatever you want to believe.You take the red pill, you stay in wonderland,
and I show you how deep the rabbit hole goes.”

This choice from The Matrix has become a cultural symbol for the choice of accepting the truth or returning to an established, familiar world. At HSI, we offer this same choice to our customers.

HSI has developed several linear position sensing solutions for a variety of customers. Our experience working with the oil and gas industry emphasizes the durability demanded from the final product. Often our assemblies will be placed in a hazardous environment and must reliably operate for long periods of time. Reed switch technology is particularly well-suited for these applications, as electronics can be completely isolated from measurements and easily designed for low power consumption in devices operating from batteries. Although we produce many sensors designed for single-point sensing in fluid controls applications, our capabilities also include developing systems that allow the determination of a location (fluid level, indicator position, etc.) along a scale.

Recently we were approached by a customer that required better than ¼” level resolution along a single axis up to 35’ long. After trying several possible solutions, we arrived at a design that met the cost and longevity requirements of our customer. The system we designed used a minimum of switches, reducing the overall cost from an equivalent design, as well as extensible technology, allowing a 5’ to 35’ unit to be produced on the same line.

HSI has experience custom-designing solutions to meet any problem. From proximity sensing to level detection, consumer devices to aerospace and fluid processing, we have a full team of engineers excited about any problem you can bring to us. As our customer you have two basic choices: Let us design a custom solution using our years of experience, or try to use off-the-shelf components to realize an effective solution.

Take the Blue Pill. Use HSI. We’ll take care of the details.
