• Highest available accuracy helps you minimize waste and eliminate bill-backs from customers
• Non-contact length measurement ensures no damage to product
• Permanently calibrated for production line simplicity
• No moving parts eliminates need for on-going maintenance
• Flexible mounting options make installation quick and easy

Adding the LaserSpeed 4000 Gauge to your production line is simple.

Just remove the existing encoder(s), and drop the LaserSpeed 4000 in place. Make quadrature or pulse output connections from the LaserSpeed to your existing control system, ensure that the LaserSpeed is installed at an appropriate standoff distance, and configure the setting for pulses per foot/meter, as desired. Connect the LaserSpeed to power, turn it on, and start measuring immediately.

For dirty production line environments, an optional air-wipe or quick-change window may be recommended to ensure measurement accuracy. Discuss this or any other concerns you may have with your Beta LaserMike Sales Representative.

Most manufacturers use a contact method of measuring length at the slitter/rewinder to ensure they have the correct length of product on the roll. They may use a contact encoder or pulses off the drive, but both methods present accuracy problems.

Any contact-based method of length measurement is subject to several types of error. Contact-based methods typically rely on measuring how fast a wheel of known circumference moves around. There will always be some amount of slippage, making it appear that there is more product on the roll than really exists. Also, the circumference of the measurement wheel can increase because of dirt buildup or decrease because of wear. The system needs to be recalibrated often to minimize error.

Inaccuracies at the slitter/rewinder may be as much
as 2%. A 2% inaccuracy on a 20,000 foot roll means 400 feet of uncertainty. If that inaccuracy is in
excess of the desired amount, each roll is costing
the manufacturer a significant amount of money in unnecessary expense. If the roll is 400 feet short,
it can also cost the manufacturer significantly in customer bill-backs.

The typical manufacturer response to this problem is to add a certain amount of “safety stock” to the roll. This costs even more money and still does not guarantee that the customer will not be shorted.

To fix this problem, Beta LaserMike offers the LaserSpeed 4000 Gauge. The LaserSpeed 4000 provides non-contact length measurement through a unique, laser-based measurement technique. Since it measures the product itself, slippage is not a problem.

This highly reliable gauge is designed for heavy industrial environments, is easy to install, and never requires recalibration. The measurement is performed optically, so there are no moving parts to wear out.

The LaserSpeed 4000’s measurement accuracy of 0.05% offers a fast payback in savings. Instead of an uncertainty of 400 foot per every 20,000 feet with the contact method, the LaserSpeed lowers the possible error to a maximum of 10 feet on a 20,000 foot roll. The LaserSpeed 4000 can literally pay for itself in a matter of weeks.

This measurement system can do even more. For example, do you have problems with speed measurement? The LaserSpeed 4000 can help you:

• Measure the product speed at any point in the manufacturing process
• Integrate a PLC or a Beta LaserMike Differential Speed Measurement System into your line to help you control stretch or draw during manufacturing
