Optical Encoder Calculator

Quantum Devices optical encoder Resolution/RPM/Frequency Calculator.

We just added a new page to the main Quantum Devices Inc. web site that provides a way to calculate RPM, Frequency, or line count (optical encoder resolution) by entering in the other two variables.

Encoder RPM-Frequency-Resolution Calculator

When would you want to use such a tool?  You might find it useful under the following circumstances:

Solving for Resolution:

When trying to determine the line count of an unknown encoder if you spin the encoder at a given RPM, then use an oscilloscope and find the output frequency, you can find out the resolution of an unknown encoder.

Solving for frequency:

If you know the RPM and line count of your optical encoder you can calculate the output frequency. This is a useful check when you are designing in an encoder to make sure you do not overrun a the input frequency limit of a drive, controller, or other device.

Solving for RPM:

This is often times used to validate the actual speed at which a machine or motor is running.

To do these calculations by hand you can check out the other blog post we have on calculating optical encoder output frequency.

Quantum Devices is a manufacturer of rotary encoders.  Incorporating QDI’s patented sensor technology, our QPhaseTM Family of Encoders feature high resolution, increased frequency response and superior reliability over temperature (0 to 120 degrees C). QDI incremental and absolute encoders set a new standard and are backed by a 2 year factory warranty. We invite you to request an evaluation unit, additional information or price quotations.

About Quantum Devices Inc.
Quantum Devices, Inc. (QDI) Barneveld, WI, was established as a Wisconsin corporation in October 1989, as an outgrowth of activities in the general area of optoelectronics. The main goal of QDI is to provide customers with a complete source for all stages of product design and development, starting from concept to a marketable commodity. These products include application specific Silicon Photodiodes, Optical Encoders and Light Emitting Diodes (LED) for commercial, industrial and medical applications. QDI's photodiodes and LED's are used in instrumentation for photosynthesis and photobiological research, biomedical and medical instrumentation for measuring blood sugar levels (glucometer), oxyhemoglobin and pulse rate (pulse oxymeter). One of the most dramatic products developed at QDI was the application of LED lighting systems for use as the light source for Photodynamic Therapy (PDT). Sales of QDI products include both domestic and international markets. Quality and reliability are very important concepts in maintaining our company wide commitment to overall product performance. Quality simply means continuous process improvement. We are committed to continually increasing our product excellence through increased quality and reliability. Quantum Devices, Inc. is ISO 9001 certified and the ISO Standard will provide the guidance for the vital function of maintaining our commitment to constantly improve our product quality. Quantum Devices is now proud to introduce it's new line of rotary encoders. Incorporating QDI's patented sensor technology, our QPhase™ Family of Encoders feature high resolution, increased frequency response and superior reliability over temperature (0 to 120 degrees C). QDI incremental and absolute encoders set a new standard and are backed by a 2 year factory warranty. We invite you to request an evaluation unit, additional information or price quotations. Mission Statement Quantum Devices is dedicated to the principle that light provides the power for all life on earth. We believe the quality, delivery and control of light is essential to the wellness of man and his advancement into the future.

    I’d like to know if you manufacture technology capable of calculating a persons quantum freaquency? Could you please point me in the right direction?

    Thank you.
