New Marine Torque Sensors Operate Wirelessly

Wireless torque sensors on boats are an innovative advancement to today’s typical boat hydraulic systems for steering and boat operation

Quality hydraulic systems are key for boat operation and steering, providing accurate weight sensing for smooth motion. According to Hydraulics and Pneumatics, this involves a delicate balance between efficiency and power, optimizing battery supply while also keeping the boat in motion.

While these systems normally involve a closed-loop circuit, a hydraulics company is updating this technology. Boats can now have wireless torque sensors.

This is just one of the many technological advances contributing to the growth of the torque sensor industry. Manufactured by Sensor Technology Ltd., this system measures the motor’s torque while enduring various loads and speeds, according to Hydraulics and Pneumatics.

“We considered different ways of measuring the torque in the motor shaft on the test rig,” Barry Wynn, Senior Design Engineer at Hy-Pro, said in a statement to Hydraulics and Pneumatics. “But all were either inconvenient or were incapable of delivering the accuracy and fast response that we needed. We concluded that TorqSense sensors offered the most reliable, easy-to-use, and cost-effective solution that would meet all of our requirements.”

Basically, this system uses a network of surface acoustic waves and transducers. This network constantly streams data in a highly efficient manner. While traditional sensors have slip rings and brushes, these wireless models forgo the need for these extra pieces, according to Hydraulics and Pneumatics.

Load cells and torque sensors already operate in harsh conditions with a temperature range of -452 degrees F to 450 degrees F. And according to Hydraulics and Pneumatics, these sensors can also handle high speeds. Specifically, the sensors can apply the torque applied at 500 to 4,000 rpm.

“The insights we’ve gained during our tests have enabled us to further enhance the performance and reliability of our steering and autopilot systems, which, of course, means big benefits for our customers and a boost to our competitive position,” Wynn said.

And entering a promising next year, the torque sensor industry may even experience even more impressive innovation.
