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.
