Dakota MultiMax – 4 Channel Bolt Tension Monitor

Overview

The Dakota MultiMax – 4 Channel Bolt Tension Monitor is a high-end ultrasonic bolt tension monitoring system developed for applications that require simultaneous measurement of multiple bolted fasteners. It is designed for engineering teams, inspectors, and maintenance professionals who need to monitor bolt load distribution, uniformity, and changes in tension across complex assemblies. Unlike single-channel bolt tension instruments, the MultiMax allows up to four bolts to be monitored at the same time, significantly improving inspection efficiency and data consistency.

The system is particularly valuable in critical bolted joints where load balance between fasteners is essential for structural integrity, sealing performance, and operational safety. Its advanced multi-channel capability makes it suitable for both static testing and dynamic monitoring during tightening, commissioning, and load testing operations.

Measurement Technology & Multi-Channel Operation

The Dakota MultiMax uses ultrasonic pulse-echo technology to measure bolt elongation and calculate applied tension for each monitored fastener. Each channel operates independently, allowing accurate measurement of bolt load on up to four bolts simultaneously. This multi-channel approach provides a clear picture of load distribution across a bolted joint, helping identify uneven tightening, load loss, or relaxation during operation.

The system supports configuration for different bolt materials, lengths, and diameters on each channel, enabling flexible use across a wide range of fastening applications. Real-time measurement capability allows engineers to observe bolt tension changes during tightening or load application, supporting precise control and validation of installation procedures.

Features & Performance

The MultiMax provides synchronized digital readout of elongation and load values for all connected channels, enabling efficient comparison between bolts. Integrated data logging allows storage of multi-channel measurement data for later analysis, reporting, and documentation. This makes the system well suited for engineering studies, commissioning activities, and long-term bolt tension monitoring programs.

Its robust design and professional-grade electronics ensure reliable operation in demanding industrial environments. The system can be used as part of advanced bolted joint analysis, maintenance planning, and asset integrity management strategies.

Industrial Applications

The Dakota MultiMax – 4 Channel Bolt Tension Monitor is widely used in applications where multiple bolts must share load evenly and reliably. Typical uses include flange assemblies, pressure vessels, turbines, structural connections, and heavy machinery installations. Industries served include oil and gas, power generation, petrochemical processing, heavy manufacturing, and infrastructure engineering. It is particularly suited for critical joints where bolt tension imbalance can lead to leaks, fatigue, or structural failure.

Installation & Use Notes

Proper ultrasonic coupling and correct transducer selection are essential for accurate bolt tension measurement on each channel. The MultiMax system is typically used during installation, commissioning, and maintenance activities where real-time monitoring of multiple bolts is required. Measurement procedures should follow established engineering practices and application-specific guidelines to ensure reliable results.
