Accurate Measurements of Vital Performance Issues, Built to Fit Your Application
Wireless torque monitoring advantages:
-
Is easy to install and integrate
-
Uses unobtrusive, lightweight hardware
-
Eliminates reliance on slip rings
-
Samples at high rate (continuous and burst)
-
Is ideal for high-RPM applications
LORD MicroStrain offers three scalable approaches to torque monitoring, ensuring reliability, accuracy, and a perfect fit within your application:
Wireless Node-Based System (battery/inductive)
Near Field Communication (NFC) Torque Monitoring System
Variable Reluctance (VR) Torque Monitoring System
Wireless Node-Based System
Real-world application: Drive shaft on UAVs and industrial pump trucks
-
Uses LORD MicroStrain wireless strain monitoring node, wireless base station, software
-
Two custom half-shells cuffed onto drive shaft or rotor
-
Proven to withstand centrifugal loads of 1250 g (standard: 500 g)
-
Continuous sampling up to 512 per second, burst sampling up to 4096 per second
-
Reliable, anti-aliasing filter to reduce data noise
-
Powered by replaceable lithium ion cells or custom inductive solution
Near Field Communication (NFC) Torque Monitoring
Real-world application: Feed system for ground-based defense application
-
Uses rotating coil and fixed-frame coil secured to shaft for power and data transmission
-
Inductive power eliminates reliance on external battery or other mounted power source
-
Electronics housed in rotating internal bobbin
-
External electromagnetic interference eliminated
-
Very low latency (average 2-4 milliseconds)
-
Less maintenance, fewer components in rotating frame
Variable Reluctance (VR) Torque Monitoring
Real-world application: Drive shaft on military aircraft lift fan
-
Uses VR sensors mounted to external fixed frame for a truly non-contact solution
-
Precisely measures all six degrees of motion (translation/rotation)
-
Angular misalignment measurement also available
-
Capable of measuring twist of less than 0.001°
-
Very low power required (can be hardwired directly into machinery)
-
Ideal for ultra high-RPM applications due to absence of mounted components
Due to the highly-specialized and unique nature of torque monitoring applications, each LORD MicroStrain solution is customized to precisely fit your particular needs. As such, these are not "off-the-shelf" solutions but rather an engineered combination of the optimal components for each application.
