HBM designs TB2 transducer for onsite calibrations

A HBM GmbH product story
Edited by the Engineeringtalk editorial team Sep 24, 2009

HBM's TB2 torque reference transducer is designed for use in onsite calibrations, such as in the calibration of torque transducers without having to remove them from the test bench.

The TB2 is available with nominal (rated) torques of 500Nm, 1kNm, 2kNm, 3kNm, 5kNm and 10kNm and is characterised by a low measurement uncertainty.

The TB2 torque reference transducer is characterised by its low sensitivity to parasitic influences such as bending moments and lateral forces

The transducer is suitable for non-rotational torque measurements.

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

The TB2 reference transducer offers low sensitivity to parasitic influences, such as bending moments and lateral forces.

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

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 two per cent; a range of 40 per cent to 100 per cent is normally required for this standard.

The strain gages (SGs) used in the measurement system enable the use of all amplifiers that support SG full bridges.

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