The RTM 2208 and RTM 2209 square drive reaction torque transducers from S. Himmelstein and Company (Hoffman Estates, IL) are characterized by high torsional stiffness, very high overload and high extraneous load capacity. Their low weight and compact size simplify installation and handling.
Verifying rotational torque applied by heavy power tools, the RTM 2208 and 2209 nonrotating torque transducers permit accurate confirmation of static and dynamic torque. They can be used while the device under test is rotating, such as calibrating torque wrenches used in make-up and breakout of drill strings in oilfield applications. The components handle capacities from 300,000 to 3,000,000 lbf-in. They are also available with Model 708+ signal conditioning instrument for data display, computer interface and I/O control.
