What are Temposonic Sensors

Overview of Temposonic sensors and industries

Specializing in high-precision linear position sensors and level transmitters, Temposonics offers the broadest range of magnetostrictive sensor solutions in terms of design, output, and performance. Our non-contact sensors provide accurate and dynamic position and velocity measurements for automation and safety-critical systems in industrial machinery, off-highway vehicles, and process industries.

Measurement enables control - and control is the key to higher productivity and efficiency, optimizing machine performance and avoiding downtime.

 How They Work

Temposonics sensors use a physics concept called magnetostriction. Here is a simple breakdown of the process: [1]

  1. The Waveguide: Inside the sensor is a stationary metal wire or tube called a waveguide.
  2. The Magnet: A permanent magnet is attached to the moving part you want to track (like a piston inside a machine).
  3. The Current Pulse: The sensor sends a tiny burst of electricity down the waveguide. This creates a magnetic field along the wire.
  4. The Interaction: When the two magnetic fields (the current and the moving magnet) cross, they create a tiny physical twist in the wire.
  5. The Measurement: This twist travels down the wire as a sound wave. The sensor's computer times exactly how long the sound wave takes to travel, and translates that into an exact distance.

 Key Benefits

  • No Physical Wear: Because the measurement relies on magnets and sound waves rather than physical contact (like a traditional ruler), the parts do not rub together. 
  • Absolute Measurement: The sensor always knows the exact location of the magnet. If the machine is turned off and on again, the sensor does not need to re-home or calibrate itself. 
  • Tough Build: These sensors are built to withstand heavy vibrations, extreme temperatures, dust, and high pressure. 

 Temposonics sensors are essential components in heavy industries. You can find them in: [1]

  • Industrial Manufacturing: Tracking the movement of plastic molding machines and metal presses.
  • Mobile Hydraulics: Measuring the extension of booms on cranes, excavators, and agricultural machinery.
  • Fluid Levels: Tracking floats in large industrial tanks to measure liquid levels.
