Junction box ensures transducers meet EMC rules.

HBM has introduced the VK20A junction box for 14 - 30 V DC supply voltages to increase the reliability of measurements by ensuring EMC-compliant connection of T20WN and T22 torque transducers to HBM amplifier systems.

The VK20A replaces the VK20 junction box because both the recently-launched T22 and the T20WN torque transducers utilize current inputs.

The T22 torque transducer is intended as a low-cost solution for applications that have less demanding accuracy requirements. Main applications include static and dynamic torque measurement on stationary or rotating parts in laboratory, test and measurement, as well as in production and process control and education.

With its compact and robust design, the transducer has a 0.5 accuracy as defined by HBM and comes in different nominal (rated) torque steps ranging from 5 N·m to 1000 N·m. The maximum permissible rotational speed ranges from 9,000 up to 16,000 rpm, depending on the measuring range.

The T20WN torque transducer, which has rated torques of 0.1 - 200 Nm, delivers an analog output signal 0 - 10 V of the torque with high bandwidth - and is therefore ideal for use in production as this output signal can be processed by all current analysis electronics.

T20WN also operates without wear and is therefore maintenance-free: The supply voltage is transferred without contact to the rotor of the transducer. The return transfer of the torque value to the stator is as an analog voltage signal.

The simple installation into the production line is another plus point for the use of T20WN for checking rotary switches. The integration of the transducer into the test configuration occurs via simple bellows couplings, which are also available from HBM as accessories.

The integrated speed measuring system in T20WN delivers 360 pulses per revolution on two tracks offset by 90°. After the edge detection, this means that 1440 pulses are available.
