How does a load pin work?
The measuring pin measures a static and dynamic tensile and compressive force. The measurement is made using a strain gauge (DMS) attached to the bolt, which is also installed in load cells, for example. The strain gauges are a precise measuring device that can measure both expanding and compressing deformations. The electrical resistance of the expansion body changes as a result of the deformation. This is determined, which makes it possible to convert the tensile or compressive force into an output signal proportional to the force.
The design principle uses the compatibility of a reduced diameter of the load measuring pins in the separation areas between a holding plate, i.e. the flanges and a central tool. This bears the main burden. The reduced diameter of the bolt creates zones of deformation. The strain gauges (DMS) are placed in these. This ensures sufficient strain concentration. This in turn is important to guarantee high accuracy and repeatability.
Advantages of a load pin
Load measuring pins are mainly used as overload protection. Components with strain gauges can be used in many working environments and offer various advantages. We manufacture tailor-made load measuring pins for you according to your individual specifications. For this we rely on modern production methods, which we have continuously optimized over time. Our manufacturing solutions allow fast and highly precise implementation for every project.
Precise
The measurement method of this design element offers high accuracy and linearity. The work can be optimized with load measuring bolts on the crane or other load devices. It not only prevents machine parts from being overloaded. It also ensures that the machines are used to their full potential.
Quality
The load measuring pins are often exposed to high loads. But even with constant use in industrial companies, Bosche load measuring pins are precise over a very long period of time. This is particularly relevant for use in machine safety.
Versatile
The possible uses of force measuring pins are diverse. Each area has individual requirements and correspondingly different requirements. Therefore, the load pin is designed by Bosche according to customer-specific requirements. So that it can be installed easily and conveniently in the existing system and is immediately ready for use. This not only ensures precise and custom-fit use. Long hold times for component integration are also avoided.
The more comprehensive and precise the information on usage, the better we can coordinate the offer for you. Among other things, we need information on the nominal load and the environmental conditions. In which temperature range do you work? Which required protection class is relevant and how big? is the distance between the measuring bolt and the instrumentation?
What different load measuring pins are there?
Our range of load cells is designed to be configured specifically for each customer to meet individual needs. Our load measuring pins differ in the basic version mainly in the cable routing.
The nominal load and size are custom-made. This makes it easy to exchange the normal connecting bolts in the machines and systems with the force measuring bolts. The load measuring pins can be made of stainless steel or alloyed steel. They are therefore also suitable for working in damp environments.
The measuring element can be hermetically encapsulated or laser welded, depending on the area of application.
Application areas of a load measuring pin
A load measuring pin is used to monitor forces in a wide variety of applications. Among other things, you will find their use in the automotive industry, in plant engineering, in construction, in aviation, in nuclear power and also in the marine sector. They are used in connection with various devices and machines:
- Cranes
- Winds
- Hoists
- Outriggers
- undercarriages
- Chain stopper
- rope points
- Cable winches
- Steel structures and pulleys
Our measuring bolts provide precise and reproducible results in long-term use in industry.
