Latest update ensures highest precision torque calibration continues

HBM has made a number of improvements to its established TB2 torque reference transducer family of products to ensure they continue to meet the needs for very high precision results delivered quickly.

It is now possible to obtain accurate, traceable measurements much more quickly, as measurements can be taken directly rather than using the familiar lever-arm calibration. The older model involved manually adding and removing weights which was a time-consuming task.

Accurate torque measurement in test bench applications is increasingly important. This means that there is a corresponding increase in the significance of calibration for the torque transducers used in these test benches.

The TB2 torque reference transducer is now available with 100 Nm and 200 Nm measuring ranges and it allows traceability to national standards. This ensures safe and reliable torque calibration across an increased range reflecting modern test bench needs.

Use of the reference transducer has been made more flexible because it is now equally suited to either non-rotational use in the laboratory or in an industrial environment. An IP67 version is now available ensuring it can be used in harsh industrial environments.

TB2 transducers already typically achieve best class 0.5, as per DIN 51309 or EA-10/14, for the minimum torque values of the measuring range, starting from 2%. The standard for this class usually only requires a range of 20 to 100%.

The TB2 also has strain gages (SG) installed that allow all amplifiers supporting strain gage full bridges to be used. This includes, for instance, the ML38B precision amplifier module for the MGCplus system from HBM.
