RCU10 Real time Orthogonal Compensator

Compensation system for real-time orthogonal position feedback.

When using any laser ruler system in a non vacuum environment, some form of environmental compensation is required to maintain accuracy under various environmental conditions. The principle of interferometric measurement depends on the wavelength of the laser, which varies slightly according to the refractive index of the air in which the laser propagates.

A temperature change of ± 1 ° C, a pressure change of ± 3.3 mbar, or a 50% relative humidity change can cause a 1 ppm difference between the laser wavelength and the measurement results.

The input and output parameters of RCU10 unit are configured using Renishaw configuration software (RCU-CS). You can download it through the link at the bottom of this page.

Features and Advantages

• precisionBy using pressure and temperature sensors to compensate for the refractive index of the laser ruler, the accuracy can be improved to within ± 1 ppm.
• Productivity improvementBy using material temperature sensors to compensate for the thermal expansion effects of workpieces and machines, the machining repeatability accuracy can be improved.
• flexibilityRCU10 can perform environmental compensation on laser rulers and linear gratings that output multiple digital orthogonal feedback signals.

Configure RCU10 system

When defining the RCU10 system, the following options should be considered:

• RCU10 compensation unit can be equipped with or without built-in pressure sensors (RCU10-PX-XX and RCU10-XX-XX respectively)
• For multi axis systems, six RCU10s can be connected through high-speed serial communication links. If used as part of a multi axis system, only one RCU10-PX-XX is required.
• Air temperature sensor
• Material temperature sensor

To determine the order number for the compensation system required for your specific application, simply enter your requirements in the gray cells of the RCU10 order number generator. It will automatically calculate the necessary system order number, which can be used for inquiries or placing orders.
