The benefits of BoltSafe through hole load cells
-
Our through hole load cells use magnetoelastic technology and are therefore more compact and less expensive than most other technologies such as strain gauges, piezoelectric technology or a similar method.
-
The load is measured very precisely across the entire surface of the ring instead of using just a few pressure points.
-
We calibrate inside the load cells and there is no (re)calibration needed at the end of the readout equipment, not even when switching between different readout methods.
-
BoltSafe sensors can be used with very low and high loads from 18 kN to 3000 kN and send out only digital signals.
-
Our thru hole load cells have almost no creep effect and are drift free. We assure a maximum deviation of 1% of the full scale after factory calibration.
-
They meet the IP66 rating and are therefore dust free and water resistant.
-
We offer various readout methods to suit many wishes, situations and applications.

What is a through hole load cell?
A load cell is initially a force transducer and is used for measuring forces such as tension, compression, torque and pressure. A through hole load cell (also called thru hole load cell) is a load cell with a hole in the middle, hence the name. The cells convert the forces into electrical signals which can then be measured and standardized. Because of this, the users can read and record the measured data. These electrical signals change proportionally to the forces applied to the sensors. There are a couple of through hole load cells available in the market, whose inner workings differ based on the chosen type. The most common used technologies are strain gauges, piezoelectric cells, hydraulic cells and pneumatic cells. They are able to convert many different forces such as tension, torque, compression and pressure. Through hole load cells are applied in many industries, wherever there is a demand for accurate and precise measurements of weight and other forces. The “through hole” shape is an advantage because it can be used around a bolt, to measure bolt load. Because of this feature, BoltSafe thru hole load cells are perfect for measuring bolt load.

How does the BoltSafe through hole load cell work?
BoltSafe through hole load cells are designed for measuring and monitoring bolt load in bolted constructions, as well during assembly as over time. Knowing this information gives better control over the construction, enhances safety and makes joints more dependable. BoltSafe’s bolt load sensor is placed on the non-driven side of a bolted connection, preferably under a nut. Tightening the bolt results in forces being applied to the through hole load cell. This causes minor deformations of the stainless steel washer. Because of this, changes in the electrical resistance occur, which can be measured using magnetoelastic technology. We use this data to determine the bolt load very precisely at any time.
Our sensors are not only applicable for measuring bolt load, but other loads, forces and weight are also possible. For example, our thru hole load cells are used for Structural Health Monitoring and in temporary constructions. Here they are used to make sure the constructions don’t collapse. BoltSafe through hole load cells are available as a CMS sensor and CMS-NC sensor. Both are available in a standard stainless steel version and in a stronger version that can withstand 15% more load while keeping the same compact dimensions.
