Force Sensor

What is a force sensor?

A force sensor measures the tension and compression forces that are applied to the sensor. There are many different kinds of force sensors, whose inner workings differ based on the chosen type of sensor. All sensors that are able to measure some kind of force can be considered force sensors. The most commonly used sensors make use of either strain gauges or piezoelectric technology. But it is also possible for a force sensor to use magnetoelastic technology or other kinds of technology, as long as they can determine and measure the force that is applied to the sensor. Most instruments are used in combination with a readout method or Data Acquisition System (DAQ) to visualize and monitor the measured force. Force sensors are used in many fields and industries, wherever there is a demand for accuracy and precision.

Force sensors by BoltSafe

BoltSafe offers a special kind of force sensor that can measure and monitor the bolt load in a bolted construction very precisely. They can be used both during assembly and over time. In contrast to most force sensors in the market, BoltSafe uses magnetoelastic technology instead of strain gauges or piezoelectric technology. Instead, our sensors measure changes in the magnetic field. Using BoltSafe sensors enhances safety, makes bolted joints more dependable and assures better control over the bolted construction.

Our force sensor is placed on the non-driven side of a bolted connection, preferably under a nut. When the bolt is being tightened and force is being applied, a minor deformation of the stainless steel washer occurs. These deformations cause changes in the electrical resistance, which our sensors constantly measure. This data is used to determine to bolt load at any given moment. BoltSafe force sensors are also suitable for use in temporary construction, to monitor the load in the construction. This way, they make sure that the construction doesn’t collapse. We offer two kinds of bolt load sensors: CMS (for continuous bolt load monitoring) and PMS (for periodic monitoring).

Benefits of a BoltSafe force sensor

  • Because we use magnetoelastic technology instead of strain gauges, piezoelectric technology or a similar method, our sensors are more compact and less expensive.
  • BoltSafe sensors measure the load across the entire surface of the ring instead of using just a few pressure points.
  • Because we calibrate on the side of the force sensor, no calibration is needed on the side of the readout method, not even when you’re switching between readout methods. This is extremely beneficial compared to other sensor technologies!
  • BoltSafe sensors have almost no creep effect, which makes them drift free. We assure a maximum deviation of 5% of the full scale in any possible circumstance.
  • The force sensors send out digital signals and can withstand very low and high loads from 18 kN to 3000 kN.
  • They meet the IP66 rating, which makes them water resistant and dust free.
  • We offer a variety of readout methods that will suit your situation and application.
