TorqueSense-Torque And Power Measurement



Torque Sense is a Shaft Torque and Power Measurement solution. It is a shaft-agnostic system, as it can be easily installed on any shaft as compared to popularly known  strain gauges for measuring torque on propeller shafts.

Measurement of the twist of the marine propeller shaft helps analyze the Torque on the shaft so it can be used effectively to limit emissions and enhance environmental sustainability.

Strain Gauges Vs TorqueSense

Torque Measurement Using Strain Gauges TorqueSense by Neptunus
Installation Transmitting an electrical signal from the strain gauge on a rotating shaft to the control unit is always challenging. Our system is non-invasive, and it can be easily installed without the need for customization, making it more convenient and versatile.
Ease of Use This method may require specialized knowledge and expertise for customization and installation. It may also involve additional steps, such as calibration. Torque Sense is designed to be user-friendly and easy to install. It provides an interactive dashboard that allows for effortless monitoring and analysis of torque data.
Methodology In this technique, strain is measured on the shaft to derive the twist angle, which is then used to calculate the torque. In this technique, the twist angle is directly measured, and from this measurement, the torque is calculated.
Accuracy and Precision Torque monitoring using strain gauges can provide accurate torque measurements when properly installed and calibrated. Our system is designed to be a reliable method for calculating torque. It provides accurate and precise torque angle calculations, ensuring the integrity of the measured data.
Compatibility This method is typically customised for a specific shaft. Once installed, it is primarily monitors the torque on that particular shaft. This solution offers compatibility with any shaft, making it more versatile. It can be used to different types of shafts without the need for customization.
Speed Limitations At low to moderate speeds, they provide accurate and reliable measurements The system has no speed restrictions. Regardless of the speed, torque sense delivers consistent and precise results.

Installation and Setup for TorqueSense

Torque Measurement System (Torquesense) is designed to provide accurate and real-time measurements of the shaft. This installation is typically performed by technical experts to ensure proper setup and functionality. The critical requirements for setup are as follows:

  • Two non-invasive MPU Sensors
  • Two Poll Bands

Step 1: Poll Band Installation

Two pole bands are mounted on the shaft at a distance of approximately 3.5 times the diameter of the shaft. These act as targets for the speed sensors. 

Step 2: Sensor Setup

Two Magnetic Pickup sensors measure the phase shift of the two signals once they are zero-calibrated. The phase shift of the signals is the Twist in the Shaft (Torsion).

Step 3: Connection To The Torque Measurement System

Following the initial setup, our technical expert will proceed to establish the connection between the sensors and the torque measurement system.

How does it work?

  • Two Pole bands are installed on the shaft at a distance of 3.5 x the diameter of the shaft. 
  • Hall Effect or MPU sensors are mounted on the brackets. 
  • These sensors transmit data to our Intelligent Controller. The Controller acquires data for 45 to 90 seconds, depending on the Sha RPM, and then analyzes it for the next 20–40 seconds. 
  • Torque (and power are displayed on the screen. Through an Ethernet switch, data can also be transmitted to the cloud.

 TorqueSense ShaPoLi

TorqueSense ShaPoLi stands out as a cutting-edge shaft power limiter, seamlessly incorporating the TorqueSense system for efficient power regulation.

TorqueSense, a torque and power measurement tool, is an important component of machine reliability. Achieving machine reliability for the marine industry is crucial, and technology like Vib360 TorqueSense plays a key role in accomplishing this goal. TorqueSense, torque, and power measurement are components of Asset Reliability Management (ARM). Achieving asset reliability for the marine industry is crucial, and products like TorqueSense play a key role in accomplishing this goal. There are a few more elements of asset reliability management. Our engine condition monitoring system based on torsional vibrations is the first condition monitoring system in the world to be class approved. It is Class certified by the IRS (Indian Register of Shipping) and ABS (American Bureau of Shipping). Apart from the asset condition monitoring system, we also provide advanced Oil Health Management Solution including an oil condition monitoring solution and an oil filtration system. Our advanced oil conditioning system sensor provides a TDN number, which will help determine the health of the oil. Our sensor detects wear particles, contaminants, and changes in oil properties. With the use of oil sensors, real-time data can be obtained without the need to send samples to a lab and wait for a report. Our solution will allow for timely maintenance decisions to be made, reducing the risk of unexpected machine failures. The most critical aspect of asset reliability management is timely maintenance services. We offer main engine maintenance services with our expert service engineers. We provide maintenance, repair, and overhaul services (MRO) for the main engine, auxiliary engines, generator sets, clutch, and gearbox. We not only render machine maintenance service, we also supply genuine spare parts for engines and propulsion systems. We deal with Niigata (OEM authorized), EMD (OEM authorized), and CAT engine spare parts.
