LaserTach®

Laser Tachometer

The LaserTach™ ICP™ tachometer senses the speed of rotating equipment and outputs an analog voltage signal for referencing vibration signals to shaft speed.  The sensor allows for measurements in excess of 30,000 RPM from distances as far as 20 inches (51 cm).  A status LED provides positive, visual indication of proper signal pickup.  The standard BNC jack connects the sensor to any constant current, IEPE conditioned data acquisition systems and signal conditioners.  Unlike magnetic tachometer pickups, the LaserTach does not require the rotating equipment to be a ferrous material - only a visually contrasting section of the shaft needs to be available.  This is typically accomplished with a small piece of reflective or retro-reflective tape.

The unit powers from standard ICP sensor signal conditioning, requiring only a single coaxial or twisted pair cable connection – like your ICP accelerometers!  No additional or specialized power source is needed.  This facilitates deployment of multiple speed sensors using the same cabling and signal conditioning as your other ICP sensor arrays.

• Operates with standard ICP sensor signal conditioning.
• Easy to install – 20 inch range in a standard bolt package offers flexibility.
• One pulse per revolution eliminates need to oversample all channels for a high frequency tach signal.
• Simplifies cable management for dynamic testing of rotating equipment.
