Contact Tachometers vs. LaserSpeed Pro

Contact tachometers are typically used in manufacturing applications for length and speed measurement. However, there are a variety of problems with the use of contact length measurement that can be avoided by replacing tachometers with a LaserSpeed Pro encoder:

Standard Tachometer	LaserSpeed Pro
Inaccuracy caused by product slippage, dirt build-up, day-to-day wear problems.	Non-contact measurement ensures high accuracy and repeatability.
High cost of ownership due to the need to regularly replace parts and recalibrate.	No moving parts ensure permanent calibration and low cost of ownership.
Contact measurement can mark or damage the product.	Non-contact measurement ensures no marking or damage of the product.

The ROI of Accurate Length and Speed Measurements

Length and speed measurement issues can dramatically affect the ability to control product speed, achieve accurate cut-to-length requirements and other critical process functions. Moreover, unreliable measurements can cost your organization a significant amount of money due to product give-away, waste resulting from scrap, loss in productivity, process downtime and other conditions. Overall, the LaserSpeed Pro length & speed gauge will keep you ahead with:

Minimizing product waste.
Reducing product shortages and overages.
Increasing product quality.
Eliminating maintenance.
Minimizing downtime.
Lowering the cost of ownership.

Issues with Bouncing, Moving Products?

Laser-Doppler Velocimetry (LDV) has been a long-proven method for accurately measuring the length and speed of products. But many applications involving producing long, continuous cylindrical products pose measurement challenges. Products that cannot be well-guided, move off-axis and move out of the measurement range make it difficult for traditional LDV-based gauges to keep the laser on the product’s surface. This results in hard-to-obtain and unreliable length and speed measurements. Cylindrical products that are small and/or have a severe curvature compound this measurement issue.

Solving Industry’s Critical Measurement Challenges

The LaserSpeed Pro M Series gauge is engineered with a proprietary optical engine not found in any other measurement system. It uses a special LDV beam method to project a unique laser pattern on the surface of the moving product. As small, bouncing and unguided cylindrical products move through an optimized measurement range, the LaserSpeed Pro M Series gauge reliably measures the length and speed with the highest repeatable accuracy. From bare conductor wire to small plastic tubing, to hot metal cylindrical rods, the LaserSpeed M Series gauge enables manufacturers to effectively control product speed and process functions in the most challenging production applications.

LaserSpeed Pro 8500X/9500X

The LaserSpeed Pro 8500X/9500X series gauge is designed for the toughest environments in metals manufacturing where heavy steam, mist and sprays occur. The LS Pro 8500X/9500X series gauge has a stainless-steel housing – a built-in air purge keeps the quick-change window clean for lower maintenance needs. The LaserSpeed Pro 8500X/9500X series gauge is well suited for a range of applications including, but not limited to hot rolling steel mills, interstand cold rolling steel mills, heavy steam applications, extreme hot and hostile environments, continuous caster, billet/bloom casters, thin slab casters, etc.

LaserSpeed Pro 8500E/9500E

The LaserSpeed Pro 8500E/9500E series gauge takes the base LS Pro 8500/9500 sensor and houses it within a rugged environmental case for double-sealed protection against hot and hostile environments. The system works on all types of products including rod, bar, tube, pipe, slabs, cold strip, hot strip, plates, profiles, lumber, etc. With various options and accessories, this gauge provides a complete solution for the harsh industrial environments.

Combining Length & Speed and Thickness Measurements

The LS Pro 8500-C/LS Pro 9500-C series is an industrial gauge that can be mounted inside the C-Frame of an X-ray gauge. The gauge can connect directly to a PLC or control computer. The LS Pro 8500-C/LS Pro 9500-C consists of a gauge, a mounting rail, a right-angle mirror assembly and a safety cover. The mounting rail is designed so the gauge can be positioned at a specified distance. This feature allows complete flexibility in optimizing the standoff distance for each application. The LS Pro 8500-C/LS Pro 9500-C gauge is well suited for applications where thickness and speed or length are required in the same location. This includes, for example, interstand cold rolling mills and foil mills.
