It is common knowledge that a decided torque is required to ensure that each fastener of components are tightened at uniform values.
On an Automobile assembly lines torque values are specified for tightening of critical components, eliminating human errors, which may lead to fatal accidents, if a single bolt may come loose.
However for certain applications Torque & Angle both are to be used in conjunction.
Normally the Torque values are specified for fasteners, on basis of its size and material specifications; however an Angular Torque too should be specified. The tightening with only consideration of torque value, does not take in account the friction factor.
Bolts of the same sizes may get tightened differently because of the material composition of the fastener, or even the age of the fasteners, due to the friction factor. Due to this factor the tightened torque value can alter, and this error can be eliminated by measuring the torque angle.
The Torque Angle is measured in degrees, after the fasteners are tightened by torque say in Newton meter or Foot Pounds values, the torque angle is applied.
Quite a few applications for Torque sensors are listed by Ricardo Bermudez of Sensing Systems which includes application for Automotive Industry’s demanding better fuel efficiency, trends towards Electric Power Steering. QC Applications like testing of Clutch and Gearboxes, Engines Dynamic Torque, Brake and Suspension Components and Bolts of Cylinder Head.
