BDI provides high-quality instrumentation services and equipment all over the world. Since the inception of BDI, one of the core competencies has been strain measurements. This started off with building our our own fully active Wheatstone bridge strain transducer to developing a variety of Wheatstone bridge completion modules for rugged field applications. With this in-house experience we now offer strain gage installation as a service for those clients that either need to have a custom component turned into a strain sensor or by sending our team of highly qualified technicians to install strain gages at our clients facilities.

WHAT WE DO SAMPLE PROJECTS OTHER SECTORS WORK WITH US

At Client’s Facility
BDI Gage Installation

Our ITAR-cleared technicians can mobilize to your facility, work during the prescribed schedules, and follow detailed client installation procedures so that your time-sensitive delivery schedules can be maintained. Our teams often work long days and through weekends and are capable of working in both supervised and unsupervised environments as well as sensitive and secure locations.

At BDI’s Laboratory
Client’s OEM Gage Installation

BDI has a full range of preparation and gage installation equipment for mounting foil gages including ultrasonic water baths, media blasters, programmable curing ovens, soldering microscopes, programmable environmental chambers, and quad-zone vacuum-operated gage bonding systems.

We are also a representative for  Vishay Micro Measurement  and supply their full range of products.

Custom Strain Gages

We provide custom-built strain gage load measuring devices to suit specific applications. Our team has more than 30 years’ experience in the design, fabrication, and calibration of these devices based on a Wheatstone bridge design using resistance strain gages. The Wheatstone bridge configuration allows for a dynamic response, increased sensitivity, better temperature compensation, and elimination of bending effects over using a single strain gage. This technology can be used to design custom-built load cells or turn existing load hardware into calibrated measuring devices. Our engineers and technicians are trained in ‘Transducer-Quality’ strain gage installation techniques to eliminate the potential of long-term measurement drift and provide the accuracy, durability, and longevity required in construction applications.

Custom strain gages

300-kip Load Cells

The design of the resistance strain gage load cell eliminates the need for large end bearing plates often required for vibrating wire load cells. Load cells are designed using 8-gage Wheatstone bridge configuration around the circumference of the load cell body to greatly reduce effects of eccentric loading. Each load cell is individually calibrated to NIS-traceble standards and come with calibration records and QA documentation. Custom design can also include external handles, plug connectors or built-in shunting capabilities depending on application needs.

4500-kip Load Measuring Bearings for Bridges

Working with Colorado DOT to measure and evaluate dynamic load capacities of rock fall netting designs, load links for netting cable hardware were instrumented with Wheatstone bridge resistance strain gages to turn existing cable/anchor hardware into accurate load measuring devices. Links were pre-calibrated prior to installation and provided dynamic load response at anchor points throughout the netting for load distribution during staged rock drops.

200-kip Load Measuring Links for Rock fall Netting

We designed load measuring turnbuckles using existing support hardware for Highway wall systems in front of Geosynthetic Reinforced Soil (GRS) abutments. Concerns for load distribution on support system during backfilling operations were mitigated through this strain-gaged, load measuring system without disturbing the load framing system. The Wheatstone bridge circuit design eliminated potential bending measurements and provided temperature compensation of measurements.

10-kip Load Measuring Turnbuckles for Bridge Abutments

Working with Colorado DOT to measure and evaluate dynamic load capacities of rock fall netting designs, load links for netting cable hardware were instrumented with Wheatstone bridge resistance strain gages to turn existing cable/anchor hardware into accurate load measuring devices. Links were pre-calibrated prior to installation and provided dynamic load response at anchor points throughout the netting for load distribution during staged rock drops.
