Load Cell

What are the benefits of BoltSafe load cells?

  • BoltSafe load cells are more compact and less expensive than strain gauges, piezoelectric or other types of load cells, because magnetoelastic technology is used.
  • The bolt load is measured across the entire surface of the ring instead of just a few pressure points.
  • Because the calibration is done in the load cell, no calibration is needed at the end of the readout equipment. No recalibration is needed, not even when you are switching between readout methods!
  • Only digital signals are sent out and the cells can withstand very low and high loads from 18 kN to 3000 kN.
  • They have almost no creep effect, which makes them drift free. There is a maximum deviation of 5% of the full scale in any given circumstance.
  • BoltSafe load cells meet the IP66 rating, which means they are dust free and water resistant.
  • We offer different types of readout methods to suit various wishes and situations.

What is a load cell?

A load cell is a force transducer that can be used for measuring force. It is able to convert a force into an electrical signal that can be measured and standardized. In this way, users can read and record the data. The inner workings differ based on the chosen type of load cell. Many different forces can be converted, including tension, torque, pressure and compression. If the force that is applied to the load cell increases, the electrical signal changes proportionally. They are widely used because they can measure weight and other forces very accurately. Load cells find their application in many fields and industries, wherever there is a demand for accuracy and precision. There are a few types on the market, such as strain gauges, pneumatic cells, hydraulic cells and piezoelectric cells. BoltSafe load cells do not fit in any of these categories, because they use a different technology: magnetoelastic technology. This technology measures changes in the magnetic field.

How does the BoltSafe load cell work?

BoltSafe load cells are specially designed to measure and monitor bolt load in bolted joints very precisely, both during assembly and over time. With this knowledge, safety is enhanced, and joints are more dependable. Better control over the bolted construction is assured! The BoltSafe bolt load cell is placed on the non-driven side of a bolted connection, preferably under a nut. While tightening the bolt, force is being applied, which will result in minor deformation of the stainless steel washer. Changes in electrical resistance caused by these deformations are then constantly measured. We use this data to determine the bolt load very precisely at any given moment.

Besides that, our washers can also be used in temporary construction. In that case, they monitor the load in the construction to make sure that the construction doesn’t collapse. BoltSafe load cells are available in two versions: for continuous bolt load monitoring (the CMS sensor) and for periodic monitoring (the PMS sensor). These are both available in a regular stainless steel version and a stronger version that can withstand 15% more load while keeping the same compact dimensions.
