UL file no.: SV17412, project no.: 08CA33386

Underwriters Laboratories visited Terawatt Research to conduct a 3rd Party Test Verification.

Underwriters Laboratories did a verification of our test set-up (IMO1) to identify the response of power, torque and speed transferred to a 2nd body via magnetic fields. The verification of the test was requested to confirm the test set-up for a study where separate bodies build up an oscillation.

• The Torque Sensors settings had to verified that they are as stated in the calibration certificates of Futek.
• The settings of the analog output channels on the Kistler CoMo Torque Type 4700 evaluation instruments had to be verified.
• The settings for the Data Acquisition System DATAQ DI710-EHS and corresponding software had to be verified.
