Torque Transducers measure torque and speed simultaneously.

Press Release Summary:



Taking measurements based on contactless sensing of anisotropic magneto-resistive sensor, Models T40B and T40FM can operate in harsh environments that contain humidity, condensation, dust, oil, and grease. Units measure torque up to 80,000 N-m and provide up to 0.03% of full scale linearity and hysteresis combined. With integrated speed measurement sensor, transducers can measure speed with 1024 pulse output. Standard response times of 1,000, 3,000, 6,000, and 10,000 Hz are available.



Original Press Release:



New HBM Torque Transducers Measure Torque and Speed at the Same Time



Marlborough, Massachusetts — HBM , Inc. (www.hbm.com), a leading manufacturer of data acquisition systems, analysis and calibration software, strain gauges, transducers and sensors, introduces new T40B and T40FM torque transducers that include an integrated speed measurement system.



HBM torque transducers are specifically designed to work in harsh environments such as those that contain humidity, condensation, dust, oil and grease. These conditions typically restrict the use of a traditional optical speed measurement system. But because the T40B and T40FM take measurements based on the contactless sensing of an anisotropic magnetoresistive (AMR) sensor, the transducer signal is more robust and stable than that of an optical system. The transducer integrates both the magnetic technology and the speed measurement sensor, which saves space and makes installation easier.



There are many industry solutions designed solely for measuring rotational speed. The T40 now stands out because its new optional speed measurement sensor lets the device measure both torque and speed (rpm) at the same time. The T40 torque transducer measures speed with a 1024 pulse output, which provides users a far higher resolution as compared to the 60 or 360 pulses than traditional optical systems provide.



In addition, because the radial or axial distance between the sensor and the magnetic ring is only 2.5-mm, the rotational speed measuring system has a high tolerance of application-related vibrations.



An optional reference pulse signal is generated by a separate sensor that senses the corresponding magnetic field in the axial direction. The system can thus provide the signals to integrate the rotational speed and the angle of rotation in the control loop of downstream equipment such as a data acquisition system (DAQ).



Other important features of the T40B and T40FM include:



Torque measuring ranges of up to 80,000 Newton-meters

Low measurement uncertainty

Good temperature stability

Up to 0.03% of full scale linearity and hysteresis combined

Standard response times of 1000, 3000, 6000 and 10,000 Hz options



"High resolution and reliability has been achieved with the new T40 speed sensing system," says HBM application engineer Mark Minda. "The transducer’s integration of torque and speed measurement capabilities results in a robust device that frees companies from worrying about testing in harsh conditions and lets them instead focus on making accurate and reliable measurements.”
