Datum Electronics offers two types of multi-element strain gauge bolt-on load cells 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.

The gauges have been designed for use in applications including vehicles, civil engineering structures, silos, 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 is very compliant and can be sued at much larger strain up to 10,000 micro-strain. The initial application was for forged vehicle axles where strains exceed 1500 micro-strain and 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 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 of Bolt-On Strain Gauge Sensors

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 bolt-on 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.

3-Hole Bolt On Strain Gauge Retro Fit Weight Sensor | Load Cell Sensor Designed To Be Fit Without Welding for Strain Measurement

Series 460 2-Hole Strain Gauge Bolt-On Load Cell

The standard 2-Hole sensor can be bolted directly 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.

Bolt-On Strain Gauge 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

  1. 4-20mA outputs:
    – 4mA = 600 micro-strain, 12mA zero, 20 mA = +600 micro-strain
    – 4mA = {customer value} micro-strain, 12mA zero, 20 mA = {customer value} micro-strain
    – 4mA = Zero, 20mA = 1000 micro-strain
    – 4mA = Zero, 20mA = {customer value}
    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
  2. 0-10Vdc outputs:
    – 0V = 600 micro-strain, 5V zero, 20 mA = 10V micro-strain
    – 0V = {customer value} micro-strain, 5V zero, 10V = {customer value} micro-strain
    – 0V = Zero, 10V = 1000 micro-strain
    – 0V = Zero, 10V = {customer value}
    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.
