Profile: J R 3, Inc. designs and manufactures multi-axis force-torque measurement. Our product line includes M & E-series sensors, receivers and cables. Our 50M31 is a member of the JR3 family of six axis force and torque transducers with internal electronics. It is 50 mm in diameter and 31 mm thick. 50M31 has signal conditioning electronics integrated into the sensor body. Included in the electronics are amplifiers and an analog to digital converter. Our JR3 multi-axis load cell is also commonly known as a 6 degree-of-freedom force-torque sensor which is a cylindrically shaped monothithic aluminum device (optionally stainless steel or titanium) containing analog and digital electronics systems. Foil strain gauges bonded to multiple internal load-bearing elements sense the loads imposed on the sensor. The strain gage signals are amplified and combined to produce analog representations of the forces along three orthogonal axes (x,y and z) as well as the moments or torques about those axes. We design and manufacture a large variety of multi-axis force-torque sensors & support electronics, collectively referred to as multi-axis load cell technologies.
