CONSTANT VISUAL INDICATION OF ENCODER QUALITY

• Constant Visual Indication of encoder quality
• Detects and displays missing signals while encoders are moving
• Tests glass scales and rotary encoders
• Tests for zero reference point
• Accepts most transducers - Accurite, Bauch and Lomb, BEI, etc.
• Self diagnostics
• Two year guarantee
• Oil tight package

Predict glass scale and encoder failures
Encoders are widely used for precise positioning in CNC’sand digital readouts. The deterioration of the output signals are not usually detected until faulty parts are made.

Now, on the testing of quadrature encoders (rotary or glass scale)is possible using a digital microprocessor device, called a QUADRATER,that detects scratches, dirty scales, and timing errors between pulses. As the signal quality decreases, the errors increase, Plugging in the Quadrater, like an extension cord,in line with your encoder you can display the quality of the encoders output. From the signal quality it is easy to predict that the encoder is going to fail.

Ideally, encoders should be periodically tested as part of a preventative maintenance (PM) program. As the light source and the mechanical parts slowly degrade, the encoder will miscount. Worn out encoders should be replaced before they cause trouble. The traditional testing method requires analysis by a trained technician using an oscilloscope, in practice this is not done because it is to disruptive to production environment.
