Introduction

Tachometer sensors provide accurate RPM readings for engines, motors, and industrial equipment. Choose contact or non-contact models based on your application.

  • Optical sensors detect reflective tape without touching moving parts, reducing wear.
  • Magnetic sensors mount directly to shafts and transmit data to digital displays or data loggers.
  • Portable handheld units allow quick spot checks during maintenance or troubleshooting.

Browse the selection to find the sensor that matches your measurement needs.

FAQs

Contact models use a rubber tip pressed against the shaft, while non-contact versions use light or magnetic fields to read speed from a distance.

Yes, both optical and magnetic sensors work on electric motors as long as you can access a rotating surface.

Follow manufacturer instructions using a known reference speed or calibration disk included with many kits.

Optical sensors may need shielding from bright sunlight; magnetic sensors are unaffected by light.

Most units toggle between RPM, Hz, and meters per minute depending on the model and sensor type.
