LaserTach1
Overview

The LaserTach ICP tachometer from The Modal Shop 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 5 feet (1.5 meters). 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 retroreflective target needs to be attached to the shaft.

Since the unit is powered from standard ICP sensor signal conditioning, only a single coaxial or twisted pair cable connection is required - exactly how your ICP accelerometers are conditioned. No additional or specialized external power source is needed, facilitating deployment of multiple speed sensors using the same cabling setup as with other ICP sensor arrays for acquiring dynamic vibration, pressure, strain or force data. The LaserTach operates using the standard constant current supplied by many data acquisition systems and all ICP sensor signal conditioners.

Benefits:

• Simplifies the acquisition of rotating equipment speed signals by operating through standard ICP sensor signal conditioning.

• Offers flexibility in positioning and mounting due to the use of long range (5 ft.) optics and standard 5/8” UNF threaded bolt package.

• Eliminates need to oversample all channels due to high frequency tach signal by always outputting 1 pulse per revolution.

• Simplifies cable management for dynamic testing of rotating equipment.
