We Are offers two types of multi-element strain gauge bolt-on strain sensors that have been developed to provide a rugged and robust production sensor with the benefits, associated with a complex strain gauge installation. They have been designed to measure tensile and compressive bending strains ranging from 50 to 1100 micro-strain, for use in applications including vehicles, civil engineering structures, silo, hoppers, vessels, and specialist engineering projects.
High Strain Bolt-On Sensors
Bolt on strain sensors are widely used, however, they are dependent on the bolting down friction. When strains exceed about 600 micro-strain and have shock loads, conventional bolt-on strain sensor will show zero shifts. The Datum design of the bolt-on strain sensors is very compliant and can be used at much larger strain up to 10,000 micro-strain. The initial application was done for forged vehicle axles, where strains exceed 1500 micro-strain and a usual bolt-on sensor had been previously dismissed.
Bolt-On Strain Gauge Sensors Specification
Our strain Gauge Bolt-on Strain Gauge Weight Sensors are quick and easy to install without any fine wiring or soldering. Its practical robust design allows the strain sensor to work in almost any environment, in any weather and even underwater if required. Rated to IP68, this is a truly universal product that will give you reliable accurate strain indication, whatever the application or environmental condition. All sensors are pre-tested and checked during final assembly, ensuring the reliability and quality of all our sensors.
