Binsfeld TorqueTrak TPM2 torque & power monitoring system

Installation & Operational Architecture of the TorqueTrak TPM2 

The Binsfeld TorqueTrak TPM2 is designed for non-intrusive installation, meaning it does not require shaft modification or machine disassembly. The system utilizes a two-part assembly to facilitate seamless data telemetry:

• Stationary Ring (Power & Data Gateway): Encircled around the shaft, this component is secured using a custom-fabricated mounting bracket tailored to your vessel’s specific engine room or deck layout. It acts as the primary interface, providing inductive power to the rotating components and receiving the digital data stream.

• Rotating Collar (Sensing & Transmission): This split-collar unit is bolted directly onto the shaft. It contains the precision strain gage and a ruggedized transmitter module. Because it is a split design, it can be retrofitted onto existing drivetrains without disconnecting the coupling.

How the Inductive Link Works

Unlike traditional slip rings that wear down over time, the TPM2 uses inductive coupling. As the shaft rotates, the stationary ring transfers power wirelessly to the rotating collar. The transmitter then sends high-fidelity, digitized signals back to the stationary interface. This data is then output via a bi-directional RS-485 Modbus interface, allowing for real-time integration into your ship’s PLC, SCADA system, or performance monitoring software.

Technical Deep-Dive: Why Engineers Choose the TPM2

The TorqueTrak TPM2 is specifically designed to solve the common challenges of long-term torque monitoring in the field:

• Non-Invasive Split-Collar Design: Unlike traditional torque meters that require cutting the shaft, the TPM2 components bolt securely around existing hardware. This preserves the structural integrity of your drivetrain and reduces installation time from days to hours.
• Zero-Maintenance Inductive Link: By utilizing an air gap for power and data transfer, the system eliminates the friction, heat, and electrical noise associated with slip rings or brushes.
• High-Resolution Digital Telemetry: With a sample rate of 4,800 Hz, the system captures high-frequency transients and torsional vibrations that lower-speed sensors miss, providing critical data for preventative maintenance.
• Superior Signal Stability: The digital RS-485 Modbus output is immune to the electromagnetic interference (EMI) often found in engine rooms, ensuring a "clean" signal to your PLC or PC.
• Field-Proven Reliability: Built to accommodate minor shaft misalignments and thermal expansion, the user-friendly collar ensures a consistent, slip-free connection without specialized machining.
