Load Cell Monitoring System for Testing Anchor Bolts
By: CAS DataLoggers
CAS DataLoggers supplied the data logging solution for a world-leading manufacturer of masonry fasteners. As part of their product development, company engineers needed to measure the peak installation load and to monitor how the load reduced as the newly- installed fastener "bedded in". Designers needed to determine such factors as bolt tightness over given periods of time (months/years)
The masonry manufacturer installed a dataTaker DT80 Intelligent Data Logger (https://www.dataloggerinc.com/
The dataTaker DT80 provided the project with a cost-effective solution, measuring the load cell at high accuracy across a ±30V input measurement range with 10 million data point storage in the internal memory. Operators had independent control of schedule size and mode, allowing them to log only when required. With the dataTaker data logger's versatile alarms and schedule rates, users sampled the data rapidly at the start of the test cycle and then slowed down the sample rate as the test continued. This unique ability reduced the large volume of data collected, making file size management and analysis easier to handle. Using the internal calculation abilities of the dataTaker logger, the peak load was recorded, and the load drop off monitored as a percentage of peak load. This value was logged for later analysis and simultaneously displayed so users could monitor the test progress without having to repeatedly connect the dataTaker data logger via computer and download the test results, saving both time and effort.
Additionally, user-friendly dEX software (https://www.dataloggerinc.com/
The masonry manufacturer's load cell monitoring system project was completed efficiently with the dataTaker DT80 intelligent data logger. The dataTaker's precision measurements from the load cell were initially taken at high sample rates, giving users an accurate picture of the structural data, and its unique ability to reduce the rate helped in the analysis phase when combing through all the data. The logger's versatile communications ports let users choose the easier way to access the data, and the free dEX configuration software was easy to learn and navigate. As a result of weeks' worth of logging, analysts had determined the bolt tightness needed for security in a wide range of structural conditions, significantly improving their product quality.
