optical speed-measurement device that bounces a laser beam off a rotating surface to read rotational speed (RPM) and to generate a once-per-revolution timing pulse. That pulse is what gives a vibration analyser its <a href=\"https:\/\/vibromera.eu\/km\/glossary\/phase\/\">phase<\/a> reference \u2014 the angular timing mark without which <a href=\"https:\/\/vibromera.eu\/km\/glossary\/balancing\/\">\u178f\u17bb\u179b\u17d2\u1799\u1797\u17b6\u1796<\/a> and most advanced rotor diagnostics are impossible. In practice a small strip of <a href=\"https:\/\/vibromera.eu\/km\/glossary\/reflective-tape\/\">reflective tape<\/a> is stuck to the shaft; the instrument detects the bright reflection once per turn, derives speed from the pulse rate, and feeds the trigger signal into the analyser for phase-locked <a href=\"https:\/\/vibromera.eu\/km\/glossary\/vibration\/\">vibration<\/a> measurements.<\/p>\n<p>Laser tachometers have largely displaced contact tachometers and magnetic pickups for vibration work. They are convenient (no shaft preparation beyond a tape strip), safe (no contact with rotating parts), and accurate. They are the standard speed-and-phase sensor for <a href=\"https:\/\/vibromera.eu\/km\/glossary\/field-balancing\/\">field balancing<\/a>, <a href=\"https:\/\/vibromera.eu\/km\/glossary\/order-analysis\/\">order analysis<\/a>, and any measurement that needs both running speed and phase. As an optical, light-based device the laser tachometer is one species of the broader <a href=\"https:\/\/vibromera.eu\/km\/glossary\/optical-tachometer\/\">optical tachometer<\/a> family, distinguished by its tight, collimated beam and long working distance.<\/p>\n<h2>1. Operating Principle<\/h2>\n<p>Two sensing methods are common, and the difference between them is mostly the quality of the target.<\/p>\n<h3>Reflective Tape Method (most common)<\/h3>\n<p>This is the reliable, repeatable approach used for serious phase work, and it proceeds in a fixed sequence:<\/p>\n<ol>\n<li><strong>Tape application:<\/strong> a small piece of reflective tape is applied to the shaft.<\/li>\n<li><strong>Laser emission:<\/strong> the tachometer emits a visible laser beam, typically red at about 650 nm.<\/li>\n<li><strong>Reflection detection:<\/strong> a photodetector senses the intensity of the returned light.<\/li>\n<li><strong>Pulse generation:<\/strong> when the tape sweeps past the beam, the strong reflection creates a sharp pulse.<\/li>\n<li><strong>Speed calculation:<\/strong> the time between pulses is the rotation period, so RPM = 60 \/ period (seconds).<\/li>\n<li><strong>Phase reference:<\/strong> the rising edge of the pulse marks the 0&deg; reference position for the revolution.<\/li>\n<\/ol>\n<p>Because each pulse fixes the instant <em>t = 0<\/em> for a turn, every vibration sample acquires a known angular position on the shaft \u2014 exactly the function a permanently-installed <a href=\"https:\/\/vibromera.eu\/km\/glossary\/keyphasor\/\">keyphasor<\/a> performs on protected machines.<\/p>\n<h3>Surface Contrast Method<\/h3>\n<ul>\n<li>Detects natural surface features \u2014 keyways, scribed marks, or colour changes.<\/li>\n<li>Needs no tape if the contrast is strong enough.<\/li>\n<li>Less reliable than reflective tape, with more risk of missed or double pulses.<\/li>\n<li>Useful for quick speed checks rather than precision phase measurement.<\/li>\n<\/ul>\n<h2>2. Key Features and Specifications<\/h2>\n<h3>Speed Measurement<\/h3>\n<ul>\n<li><strong>Range:<\/strong> typically 10&ndash;250,000 RPM.<\/li>\n<li><strong>Accuracy:<\/strong> &plusmn;0.01&ndash;0.05% of reading.<\/li>\n<li><strong>Update rate:<\/strong> real-time display, refreshing several times per second.<\/li>\n<li><strong>Resolution:<\/strong> 0.1 RPM typical.<\/li>\n<\/ul>\n<h3>Distance (working range)<\/h3>\n<ul>\n<li>Typical standoff: 50&ndash;500 mm (2&ndash;20 inches) from the target.<\/li>\n<li>Achievable distance depends on laser power and the quality of the reflective tape.<\/li>\n<li>Too close and the beam spot becomes too small to land reliably on the tape; too far and there is insufficient reflected light to trigger.<\/li>\n<\/ul>\n<h3>Output Signals<\/h3>\n<ul>\n<li><strong>Digital display:<\/strong> RPM read out directly on screen.<\/li>\n<li><strong>Analog output:<\/strong> a voltage proportional to speed (0&ndash;10 V typical).<\/li>\n<li><strong>Pulse output:<\/strong> a TTL or logic pulse once per revolution \u2014 the signal the analyser actually uses.<\/li>\n<li><strong>Direction:<\/strong> some models detect the direction of rotation.<\/li>\n<\/ul>\n<h2>3.

Reflective Tape: Selection and Application<\/h2>\n<h3>Types and Selection<\/h3>\n<ul>\n<li><strong>Retroreflective tape:<\/strong> reflects light straight back to the source, making it the most effective and tolerant of aiming angle.<\/li>\n<li><strong>Aluminium tape:<\/strong> good reflection and economical.<\/li>\n<li><strong>White tape:<\/strong> adequate for many applications.<\/li>\n<li><strong>Size:<\/strong> 10&ndash;25 mm (0.5&ndash;1 inch) is typical.<\/li>\n<\/ul>\n<h3>Application Best Practices<\/h3>\n<ul>\n<li>Clean the surface before applying the tape.<\/li>\n<li>Apply it on a smooth, cylindrical section of the shaft.<\/li>\n<li>Avoid any location where the tape could contact stationary parts.<\/li>\n<li>Use a single piece per revolution \u2014 multiple pieces confuse the instrument.<\/li>\n<li>Press the edges down to prevent peeling at high speed.<\/li>\n<li>Mark the angular position if the tape will serve as a balancing reference.<\/li>\n<\/ul>\n<h2>5. The Laser Tachometer in the Field<\/h2>\n<p>On a portable instrument the tachometer is not an accessory \u2014 it is the component that makes single- and two-plane balancing possible on site. The <a href=\"https:\/\/vibromera.eu\/km\/%e1%9e%95%e1%9e%9b%e1%9e%b7%e1%9e%8f%e1%9e%95%e1%9e%9b\/balanset-1\/\">Balanset-1A<\/a> ships with an optical laser tachometer that triggers from a strip of reflective tape, working at 50&ndash;500 mm standoff across a 250&ndash;90,000 rpm range. Its once-per-revolution pulse supplies the phase reference the software needs to compute the <a href=\"https:\/\/vibromera.eu\/km\/glossary\/correction-weight\/\">correction weight<\/a> mass and angle, and then to confirm the <a href=\"https:\/\/vibromera.eu\/km\/glossary\/residual-unbalance\/\">residual unbalance<\/a> after correction. Because the same pulse also yields a precise RPM, the engineer can match measured frequencies to specific components and separate, say, running-speed <a href=\"https:\/\/vibromera.eu\/km\/glossary\/harmonics\/\">harmonics<\/a> from <a href=\"https:\/\/vibromera.eu\/km\/glossary\/bearing-fault-frequencies\/\">bearing fault frequencies<\/a> in one survey.<\/p>\n<h2>6. Advantages Over Other Tachometers<\/h2>\n<h3>vs. Contact Tachometer<\/h3>\n<ul>\n<li><strong>Laser:<\/strong> no contact, safer, no shaft damage, works at any speed.<\/li>\n<li><strong>Contact:<\/strong> requires physical contact, introduces friction, limited to lower speeds, and risks damage to the shaft surface.<\/li>\n<\/ul>\n<h3>vs. Magnetic Pickup<\/h3>\n<ul>\n<li><strong>Laser:<\/strong> works on any material, needs only a simple tape application, and allows precise positioning of the reference mark.<\/li>\n<li><strong>Magnetic:<\/strong> requires a ferrous target, usually a permanent installation, and offers less positioning flexibility.<\/li>\n<\/ul>\n<h3>vs. Strobe Light<\/h3>\n<ul>\n<li><strong>Laser:<\/strong> gives a direct, quantitative measurement and a phase-reference output.<\/li>\n<li><strong>Strobe:<\/strong> a <a href=\"https:\/\/vibromera.eu\/km\/glossary\/stroboscope\/\">stroboscope<\/a> offers visual observation only \u2014 it matches a flash rate rather than measuring, and provides no phase signal.<\/li>\n<\/ul>\n<h2>7. Common Issues and Solutions<\/h2>\n<h3>Unstable or Missing Signal<\/h3>\n<ul>\n<li><strong>Causes:<\/strong> dirty optics, wrong standoff distance, poor-quality tape, or ambient-light interference.<\/li>\n<li><strong>Solutions:<\/strong> clean the lens, adjust the distance, replace the tape, and shield the target from bright light. Direct sunlight on the sensor is a frequent culprit and is cured by shading.<\/li>\n<\/ul>\n<h3>Incorrect Speed Reading<\/h3>\n<ul>\n<li><strong>Multiple tape pieces:<\/strong> produce a reading that is a multiple of the true speed (double triggering).<\/li>\n<li><strong>Reflective surface:<\/strong> a shiny shaft or a second bright feature can be detected instead of, or in addition to, the tape.<\/li>\n<li><strong>Solution:<\/strong> ensure exactly one reference mark per revolution and use matte tape with careful aiming.<\/li>\n<\/ul>\n<h3>Phase Measurement Errors<\/h3>\n<ul>\n<li>The tape position has shifted from its original reference angle.<\/li>\n<li>The tape is peeling or creeping during operation.<\/li>\n<li><strong>Solution:<\/strong> secure the tape properly, verify its position, and reapply it if needed.<\/li>\n<\/ul>\n<p>Laser tachometers are essential tools for modern vibration analysis and balancing, delivering safe, accurate, non-contact speed and phase measurements. Their combination of convenience, precision, and versatility has made them the standard for field vibration work, replacing older contact and magnetic technologies in most industrial applications.<\/p>\n<hr>\n<p><a href=\"https:\/\/vibromera.eu\/km\/glossary\/\">\u2190 Back to Main Index<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Learn about laser tachometers, optical speed measurement devices using laser reflection from rotating surfaces or reflective tape for precise RPM and phase reference measurements.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"ai_generated_summary":"","footnotes":""},"categories":[109,113],"tags":[],"class_list":["post-20645","glossary","type-glossary","status-publish","hentry","category-glossary","category-measurement"],"_links":{"self":[{"href":"https:\/\/vibromera.eu\/km\/wp-json\/wp\/v2\/glossary\/20645","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vibromera.eu\/km\/wp-json\/wp\/v2\/glossary"}],"about":[{"href":"https:\/\/vibromera.eu\/km\/wp-json\/wp\/v2\/types\/glossary"}],"version-history":[{"count":1,"href":"https:\/\/vibromera.eu\/km\/wp-json\/wp\/v2\/glossary\/20645\/revisions"}],"predecessor-version":[{"id":101355,"href":"https:\/\/vibromera.eu\/km\/wp-json\/wp\/v2\/glossary\/20645\/revisions\/101355"}],"wp:attachment":[{"href":"https:\/\/vibromera.eu\/km\/wp-json\/wp\/v2\/media?parent=20645"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vibromera.eu\/km\/wp-json\/wp\/v2\/categories?post=20645"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vibromera.eu\/km\/wp-json\/wp\/v2\/tags?post=20645"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
