TM-HA, The New Non-Contact Rotary Torque Sensor From Fast Technology, Features Added Accuracy And Toughness For Real World, Shop Floor Applications At A Low Price
These innovative new non-contact sensors make torque measurement a practical, low-cost, high-performance measurement and safety tool.
November 7, 2001 - FAST Technology (Livonia, MI), the leading name in non-contact torque sending, has introduced the TM-HA, the latest addition to FAST Technology's Embedded Magnetic Domain (EMD) torque sensing line. Like other EMD torque sensors, the robust and low-cost new TM-HA can measure the torque applied to a rotating or a stationary shaft without contact, providing torque values at high frequency with high resolution, repeatability and accuracy. This combination of robust design, virtually maintenance-free performance and economy is bringing torque measurement out of the testing lab and into demanding, real world applications, attracting the active interest of many of the world's largest auto companies, auto suppliers and power tool manufacturers.
The TM-HA brings an array of new benefits and features to this impressive line of torque sensors, including higher accuracy, greater corrosion resistance, improved resistance to magnetic fields, and an extended range of sensors and accessories like a square drive sensor fixture that allows the TM-HA to be used as a test bench for power tool and torque wrench
How it Works
With the TM-HA, as with other Embedded Magnetic Domain sensing systems, shafts are conditioned with a permanent magnetic pattern. The magnetic characteristics of this pattern vary in response to the level of torque applied. EMD non-contact sensors measure this ariation and give an output signal proportional to the applied torque. Standard Embedded Magnetic Domain torque sensors are designed to measure torque up to 1000 Nm (737 Ft-pd).
The TM-HA, like other FAST Technology Embedded Magnetic Domain torque sensors, is supplied as a complete measurement system packaged in a single housing including torque shaft, signal detector, electronic signal processing unit, connector and cable. FAST Technology has minimized the sensor signal processing electronics in the form of a recently introduced ASIC. This reduces the space required for sensing and electronics, to the point that it is actually included in the sensor housing.
Non-intrusive and easily installed, FAST Technology's Embedded Magnetic Domain sensors are characterized by low power consumption, high output signal level, long-term measurement stability and low cost, rendering them the torque measurement solution of choice for a wide array of applications, including automotive, aerospace, power tools, machine tools, process control, textile machinery, printing machinery, oil well drilling...and many more.
