(S. Himmelstein: Chicago) -- To verify the amount of rotational torque applied by heavy power tools, these stationary (nonrotating) transducers permit accurate confirmation of static and dynamic torque. The RTM 2208 and 2209 transducers can be used while the device under test is rotating, such as when calibrating torque wrenches used in make up and break out of drill strings in oilfield applications.

They carry capacities from 300,000 to 3 million lbf-in, and offer a compact mechanical package that is a cost effective alternative to rotating torque transducers—which have a much higher cost and greater complexity of installation.

In applications such as determining the torque required to open or close large valves, the S. Himmelstein’s square drive reaction torque transducers are characterized by high-torsional stiffness, very high overload, and high extraneous load capacity. Their light weight and compact size simplify installation and handling. All models are calibrated CW and CCW to rated load in the S. Himmelstein NVLAP-accredited laboratory (NVLAP Lab Code 200487-0).
