Exploring Actuation Mechanisms Of Length Gauges In Machine Control Systems

The three main types of actuation mechanisms used by length gauges in machine control systems include spring-actuated plungers, pneumatic actuation and motorized actuation. Walker Machinery, a leading distributor of CNC control systems and digital encoders in Milton, Ontario, explores these 3 length gauge mechanisms in detail.

What Are The 3 Length Gauge Actuation Mechanisms?

Spring-Actuation

This mechanism features a built-in spring that exerts moderate and constant pressure on the plunger. This helps the plunger to extend towards the workpiece to be measured. A spring-actuated mechanism is key in length gauges, as this provides consistent contact and prevents deformation or incorrect reading when measuring the object.

Pneumatic Actuation

Instead of a spring, in the case of pneumatic actuation, compressed air is used to exert pressure on the plunger. This helps the plunger extend towards the workpiece and perform its task. It is a more advanced form of length gauge mechanism, and as such, it is mainly used in automated measuring stations and machine control systems. 
 

This is because the plunger can be controlled by automatically varying the air pressure of the compressed air. If the air pressure is removed, this mechanism also has a spring to send the plunger back to its starting position.

Motorized Actuation

These are featured in more high-end length gauges. As the name suggests, it features a small internal motor to move the plunger of the gauge. This feature makes the process automated and easy to control. Furthermore, it also allows the gauging force to be adjusted via a remote controller. Motorized actuation is best-suited for long travel distances, in the range of 60 to 100mm.

Conclusion

To summarize, length gauges can operate in machine control systems via spring action, compressed air or motor control.
