Kistler Torque Measuring Flange Model 4504A operate on the strain gauge principle. The integral, digital measuring preconditioning system produces analog or digital output signals, which are transmitted without contact. The rotor runs in the stator ring without mechanical bearings and is therefore free from wear.

• Digital telemetry non-contact signal transmission
• Rated torque: 200 ... 5,000 Nm (1,770 ... 44,253 lbf-in)
• Speed ranges up to 15,000 rpm
• Accuracy class: 0.1%, 0.05% optional
• Very short axial dimensions
• Compact flange-to-flange solution
• Strain gauge measuring system
• Very high accuracy
• Maintenance-free, bearingless
• Electronic control of sensor
• Magnetic speed measurement

Description
Model 4504A... torque measuring flange was designed to be a very short flange-to-flange solution and its rotor can be installed from one side (normally the test specimen side), straight to the flange of the loading machine. This allows easy, cost-effective assembly into a power train.

Application
The extremely narrow profile of the Model 4504A... torque measuring flange makes it very suitable for many test rig applications: Test bed for engines, dynamometer, wheel load simulation, gear boxes, pumps, electric motors and many others.
