DEVELOPMENTS IN CONTINUOUS TORQUE MONITORING COUPLINGS

摘要

The use of continuous torque monitoring couplings is quickly becoming an integral part of many predictive maintenance programs in the petrochemical and process industries. More and more operating facilities are using instrumented torque-measuring couplings in order to know how their critical equipment is performing so that the intervals between scheduled shutdowns can be chosen appropriately. This paper will cover a brief history of torquemeters; i.e., the basic measuring types which are 1) strain gage types and 2) torsional deflection types. Discussed will be the theories of operation on how they work and the advances and limitations of these types. Included will be the accuracies that can be obtained by each one and the features of each. In addition, recent advancements in the electronic technology will be discussed.
