HBM launches TB2 torque reference transducer

HBM's TB2 torque reference transducer has been designed as a reference and transfer transducer for use in on-site calibrations.

It is available with the nominal (rated) torques of 500Nm, 1kNm, 2kNm, 3kNm, 5kNm and 10kNm, and is characterised by a low measurement uncertainty.

The TB2 is said to be particularly suitable for non-rotational torque measurements.

It is available with a hermetically sealed design and protection class IP67, as per EN 60529 for use in challenging ambient conditions.

In addition to high accuracy, the TB2 reference transducer is said to be characterised by its low sensitivity to parasitic influences such as bending moments and lateral forces.

Sensitivity to ambient influences, such as temperature deviations is also low, thanks to the enclosed geometry of the measuring body.

The TB2 can meet all general climatic challenges in an operating temperature range of -50C to +80C.

Originally developed for industrial applications, the TB2 can also be used as a transfer transducer for torque calibration under laboratory conditions because of its high precision.

The TB2 transducer typically reaches its best class of 0.05 as per DIN 51309 or EA-10/14, for measurement range initial values from 2 per cent; a range from 40-100 per cent is normally required for this standard.

The strain gages used in the measurement system enable the use of all amplifiers that support strain gauge full bridges.

This includes, for example, HBM's ML38B precision amplifier module in the MGCplus system.
