Reasons to Measure and Monitor Torque and Power

In the simple model, there is a drive and a workload with a shaft in between.  Knowing the true mechanical torque and power on the shaft is especially valuable when it comes to commissioning new equipment or maintenance and troubleshooting of existing equipment.
In the photo above, the TorqueTrak Revolution instrument is used in this Safety Coupling made by our sales agent in Brazil, Torkflex Transmissões Industriais Ltda.  The equipment is in a sugar processing plant.  The coupling name is TORKMILL.  The TorqueTrak Revolution senses any "high torque" that might occur and then interrupts the drive before any damage can be done to the equipment.

“Why do I need to measure torque and power?  Why is it important?”

Great questions!  My simple answer: “Because it saves time and money.”  Here are some reasons, in terms of time and money, why it is important to measure true mechanical Torque & Power on rotating shafts.

High/Low Torque Alarm – Continuously monitor the shaft Torque to make sure the load stays within safe operating limits, thereby preventing premature fatigue and/or failure of the equipment.  Use the TorqueTrak Revolution output signal to sound an alarm and/or shut down the equipment when the load exceeds the safe limit.  TorqueTrak Revolution Response Time: 2 msec max.

Optimize Fuel Efficiency, Marine – Verify the true Power output of the engine(s).  The true Power output is critical in the propulsion efficiency analysis and emissions analysis.  Compare Fuel Input to Engine Power Output to Vessel Speed.

Load Management – Continuously monitor the material load on conveyor equipment, as indicated by the Torque on the drive shaft, and speed up or slow down the process accordingly; even stop the process altogether in the case of a material jam, before any damage can occur to the equipment.  TorqueTrak Revolution monitoring instrument, Response Time: 2 msec max.

Diagnostics – Learn how much mechanical Power (Hp or kW) is truly needed to accomplish a task.  Learn why there is a humming noise (torsional vibration.)  Learn why the coupling broke (excessive start-up torque.)

Preventive Maintenance – Diagnose and eliminate a torsional vibration condition that, if left unchecked, will result in premature fatigue and/or failure of the equipment.

These are some of the basic ways Torque & Power measurement can save time and money for just about any operation where there is a rotating shaft.  The TorqueTrak instruments are used in many different industries and applications all around the world.

Binsfeld Engineering recently introduced the new TorqueTrak TPM2 torque and power monitoring system for rotating shafts. The all-digital system features a RS422 full-duplex interface with system setup and configuration via computer software (provided).

Like all Binsfeld Engineering torque telemetry systems, the TorqueTrak TPM2 does not require shaft modification or machine disassembly. Rugged and precise, the TorqueTrak TPM2 is available for shaft diameters from 0.75"(19mm) to 40 inches (1016mm) and is ideal for almost any torque and power evaluation project.


Continuous Torque and Power Data

Designed for permanent installations and continuous monitoring, the TorqueTrak Revolution instrument from Binsfeld Engineering Inc. provides continuous output data from the rotating shaft for four key parameters: torque, power, RPM and direction of rotation. It is an inductive, non-contact system - no batteries, no wear surfaces - machined to fit the shaft, up to 40 inches diameter.

TorqueTrak 10K
Fast & Easy Torque Measurements

For temporary testing or short term measurements it doesn't get much easier than the TorqueTrak 10K telemetry instrument from Binsfeld Engineering Inc. Accurate and simple to use, the TorqueTrak 10K fits any size shaft and any torque level. It is ideal for field work and troubleshooting marine propulsion systems, drive systems, compressors, conveyors and other large machinery. Normally, units are in stock, ready to ship.
