ABSTRACT
A. General 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 these instrumented torque-measuring couplings in order to know how their critical equipment is performing so that intervals between scheduled shutdowns can be chosen appropriately. Also, when energy costs rise, competitive pressures demand that operating facilities run their equipment as efficiently as possible, adding to the popularity of these so-called torquemeter (or torsionmeter) couplings.
