Datum Electronics offer two types of multi-element bolt-on strain sensor 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 stresses ranging from 50 to 1100 micro-strain.
The gauges have been designed for use in applications including: vehicles, civil engineering structures, silos, hoppers and specialist engineering projects.
Specification Our Bolt-on strain sensors are quick and easy to install without any fine wiring or soldering. Its practical robust design allows the 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.
Diversity Using the latest strain gauge techniques and technologies it gives you the accurate and reliable data you require in a number of challenging environments. The sensors are fully compatible with our wide range of load and strain indicators and amplifiers allowing you to operate any number of sensors in parallel for your application. A direct serial link to a PC, or an analogue input to a data logger or PLC, is also an option and also very easy to achieve. The Series 460 Bolt-on strain sensor is not only an essential product for measuring micro-strain, but it can also become an integral part of a strain monitoring system.

Series 460 2-Hole Sensor
The standard 2-Hole sensor can be bolted direct to the structure for use in a range of applications and environments. We recommend that the structure on to which sensor is to be bolted should be at least 10 times larger than the sensor, for accurate and reliable measurement data. |

Series 460 3-Hole Sensor
The 3-Hole sensor has a unique design eliminating the temperature effect on bending and strain of the application, providing a far more effective strain indication than a standard 2-hole option.
As the external temperature of the application fluctuates, the bolt-on sensor compensates for this and distinguishes this change from the measured strain of the application. Highly sensitive with effective temperature compensation built in this product, makes an incredibly useful and cost-effective method of measuring strain. |
