Ideal for use in measuring reaction torque in assembly operations!

• Measure reaction torque characteristics of assembly operations
• Maintenance free with no moving parts
• Wide variety of standard capacities with custom units available

We can supply a complete line of reaction torque sensors in capacities from 50 lb-in up to 250,000 lb-in. Using a full bridge strain gauge design, the 3100 Series of reaction torque sensors contains no moving parts and is virtually maintenance free. If one of our standard designs is not suitable for your application, we will provide a quotation for a special unit based on your specific requirements.

When used to support a pneumatic or electric nutrunner, care must be taken to assure that all reaction to the output spindle torque is carried through the transducer. Air or hydraulic hoses, piping, cables, and the mounting design must not offer a secondary path to ground. Side forces and non-flat mounting of flange to flange units should be held to a minimum.
