  • Jet Engine Balancing: Laser Tachometer...Friend or Foe?
    This paper briefly outlines the differences between the two most commonly available methods of obtaining this signal; the laser tachometer and odd tooth detection.
  • Using DC Tachometer Generators
    The current thinking in motion control these days is . Computer generated movement routines, encoder feedback, PWM amplifiers, stepper motors, etc. Digital technology has brought many good things to motion control. But sometimes the old ways are better. If you are working with a motor controller
  • Recent Special Applications
    Low-inertia DC motor with integrated tachometer and speed reducer
  • Procedure to Verify Proper Operation of Tachometers and Optical Sensors
    When a Tachometer/Sensor has a visible light output and has passed the fluorescent light calibration check, THERE IS NOTHING WRONG WITH THE TACHOMETER ORSENSOR. We suggest trying a new piece of Reflective Tape or contrasting color, holdsteady and aim from the correct distance to obtain actual RPM.

  • W7 Installation
    How to install TACHLINK software on Windows 7, 32 and 64 bit operating systems. Includes resolution; if tachometer is not recognized by PC when connected via USB.*
  • Medical Device Link .
    in the world of motors and motion control devices. Tachometer Uses Both Analog and Digital Signals A tachometer encoder combination offers both analog velocity and digital position signals in one device. The dc tachometer from (Hawthorne, NJ) has an encoder that uses high-quality optical sensors
  • Evaluating A Closed Loop Control System For High Pressure Pumps
    Prosig were recently involved in the validation of a closed loop control system for an automotive pump supplier. The customer has a large number of test cells, each test cell has 8 pumps continually on test. Each pump is instrumented with a revolution or tachometer sensor, giving a once per
  • Measuring Torsional Crank Shaft Jitter
    Using Prosig's P8000 series data acquisition system with DATS signal analysis software, torsional analysis (crank jitter) was performed on an automotive engine attached to an engine dynamometer. The significance of this is that only one tachometer channel was required to identify crank jitter.
  • How to Select a Strobe
    will appear to stop. rotating and their eyes will see the "Stopped Motion". Monarch provides a very detailed Instruction. Manual on How To Use the Strobe. If you decided to purchase a Tachometer instead of a Stroboscope,. please read How to Specify Monarch Tachometers.
  • Models 441A and 441AL Frequency-to-Voltage Applications
    Simply put, a frequency-to-voltage converter is a fancy tachometer that produces an analog output representing the frequency of an applied ac input signal. With an input frequency range of 1 Hz to 50 kHz and an output voltage range of -10 V to +10 V, the Ectron Models 441A and 441AL offer precise
  • Correcting errors that never happen
    controller was typically a CNC device responsible for closing the proportional-gain (P) loop and, if used, the steady-state or integral gain ( I ) loop. A tachometer (tach) or speed loop was used in lieu of a derivative-gain (D) function. The closed position and speed loops configured by this type
