Shaft torque measurement systems are custom-designed by IR Telemetrics, the technology leader in data acquisition. The newest shaft torque measurement system, Phase-Torque, is a non-contact torque sensing technology that enables continuous measurement of power and torque with no electronics on the rotating shaft. The system will hold up under extreme conditions and can operate as a monitoring system for ship propellers, industrial machinery, or transportation systems.


The Phase-Torque system can be installed on shafts of any diameter with minimal space requirements and once installed, it measures shaft torque and RPM simultaneously. It has a high-frequency response and is useful for monitoring system performance over short and long periods of time. For example, output can be guaged over months or years of wear during operation. It can provide insight to variations in torque caused by machinery malfunctions. Although this is a standard product, IRT provides appropriate support for any application.
