Our series 460 2-hole bolt-on sensor is not only an essential product for measuring micro-straight, but it can also become an integral part of a strain monitoring system for using in harsh environments.
Datum Electronics 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.
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.
Rated Strain Range: 10 – 1,100 micro-strain
Rated Output: 1.5mV/V for 1,000 micro-strain (nominal)
Repeatability: 0.1% FSD
Envrironmental Protection: IP68
Operating Temperature: -20ºC to +80ºC
Bolt-On Strain Sensors Output Options
Raw Strain Gauge Bridge Output – the bolt-on sensor has a four wire connection to the strain gauges that are configured as a Wheatstone bridge. This output will require an amplifier. It will be compatible with most strain gauge amplifiers and indicators. Should your indicator require a 6-wire input, refer to our connection guide.
Note when selecting your output value please allow for the sensor to show up to a 200 micro-strain offset when bolted to surface that is not flat. Even with ground flat surfaces a small offset will occur
