RetroBolt™ Force Sensor

The RetroBolt-M-xx-ICA series of piezo-electric force sensors provides a direct measurement of force in tension or compression. Each sensor includes an integrated charge amplifier for high-sensitivity, low-drift, low-impedance output signals. These sensors are packaged as tension-sensitive washers for use under load-bearing bolts. Here, they measure the small changes in bolt tension that result from cutting forces exerted on the tool. In many applications, they provide truly retrofittable force-monitoring capability without the need for any mechanical modifications to the machine. RetroBolts can be installed quickly and easily on lathes with bolt-on turrets or tool blocks. In this type of application, RetroBolts can be used to detect overloads or collisions, missing grooving tools, and gross tool breakage.

Montronix presents force sensors with integrated charge amplifiers (ICA) designed specifically for fixed tool applications such as lathes, presses, and broaches.

Montronix force sensors with ICAs provide:

• Available in retrofittable versions as well as the more traditional versions designed to be embedded within the machine structure
• Improved reliability and easier maintenance in the harshest industrial process monitoring applications
• Fast response time to detect force transients caused by tool breakage
