Bolt Load Measurment

Sonar - Bolt Elongation

The Sonar DS-90 is a specialized ultrasonic time-of-flight (TOF) measurement device designed by Tension Pro, and officially distributed in India by ABS. This single-purpose unit measures, displays, stores, and transfers bolt load and elongation data in a rugged, single-purpose unit. This capability is critical for ensuring bolted joints are tightened correctly to the design specification, thus avoiding joint leakage, mechanical, or fatigue failure. The unit is ideal for long-term monitoring of bolt load to ensure the integrity of critical assets.
Features

Features for Data Integrity & Usability

The intuitive software and hardware are developed specifically for the bolting industry, ensuring ease of use and secure data management.

  • Secure Data Collection: Data is collected securely and is password protected.

  • Traceability: Stores the real time echo trace with each reading. Date/time is stored with every reading via a real time clock.

  • Data Transfer & Storage: Data and digital signal traces are stored for later display and can be transferred via USB to a computer.

  • Temperature Compensation: Has automatic temperature compensation through an included magnetic temperature probe.

  • Transducer Versatility: Compatible with a full range of magnetic, non-magnetic, and glue-on transducers to suit specific bolt requirements.

  • Customization: The unit is fully customisable for flexible and programmable data storage.

Why Choose Sonar DS-90

Choose the Sonar DS-90 for verifiable quality, portability, and specialized knowledge integration:

  • Verifiable Accuracy: The hybrid technique ensures fast signal acquisition and precise single shot TOF measurement, translating directly to confidence in bolt load verification.

  • Operator Focus: The latest colour touch screen technology and intuitive software, developed with input from experienced bolting users, ensure easy and quick operation.

  • Long-Term Asset Integrity: Ideal for long term monitoring of assembly bolt load to ensure the integrity of your asset.

  • Local Support: As the official distributor, ABS provides local inventory for quick delivery and offers 24 hour expert support.

Applications

  • Bolt preload verification: Measures bolt elongation and time-of-flight to confirm accurate preload on critical fasteners.

  • Industrial infrastructure: Ideal for oil & gas, power generation, wind energy, and heavy construction where high-load bolted joints require reliable integrity checks.

  • Maintenance & inspection: Enables quick, non-intrusive bolt load checks during shutdowns or when bolts face heat, vibration, or cyclic loads.

  • Foundations & structural bolts: Verifies tension and elongation in large foundation and structural bolts used in heavy machinery and civil structures.

  • Custom bolted applications: Real-time echo trace storage and programmable data make it suitable for specialised applications requiring high traceability—such as offshore, aerospace, and turbine rotor bolts.

Portability: Battery torque wrenches offer portability and flexibility without the need for a power cord or hydraulic hoses, making them ideal for remote or confined spaces. Precision and Control- Many battery torque wrenches feature programmable settings that allow for precise torque control, which improves consistency and reduces the risk of over-tightening. Reduced Physical Strain- These tools often use high-torque output with minimal effort, reducing operator fatigue and improving productivity in repetitive tasks. Versatile Applications- Battery-powered wrenches are suitable for a wide range of applications, including assembly lines, maintenance, and industrial settings. Time Efficiency- The speed and ease of using a battery-operated tool can increase workflow efficiency, especially in applications that require multiple fastenings or repeated torque adjustments.
