Electronic dynamometers: the application in weighing systems
How do dynamometers work and where are they applied? Here are the answers to the most frequently asked questions
NBC Elettronica Group, a leader for 40 years in the field of industrial weighing systems, produces 3 different types of dynamometers to meet the various requests and needs of clients.
But what is this object for and what applications does it have in the industrial sector?
The dynamometer (from Greek: δύναμις, dýnamis, force, power and μέτρον, métron, measure) is a measuring instrument that determines the magnitude of a force applied to it and uses the principle of Hooke’s law, whereby the deformation of an elastic material is directly proportional to the force applied to the material itself.
Industrial models used in mechanics generally consist of a load cell with processing electronics to which an object with mass can be hung, measurable in kg or Newtons.
The dynamometer: from the medical sector to weighing goods
The general objective is the measurement of weight force, that is, the mass of an object for the acceleration of gravity (what we commonly simply refer to as weight). There are dynamometers available commercially with various capacities: from a few Newtons to 100 tons and beyond.
All our dynamometers are electronic and are equipped with a safety hook, high visibility display, battery for powering the dynamometer, and charger. Some models are equipped with a remote control for the on/off, tare, and print functions. Here are some of our products.
The application sectors are numerous:
- incoming material control (material bars such as iron, aluminium, or stainless steel, marble blocks, etc.);
- medical sector both for monitoring patient weight and for assessing muscle strength in rehabilitation contexts;
- weight control in port operations;
- tensioning of electric lines;
- testing of samples in material testing machines;
- control of the catch.
Different types of dynamometers
There are not only digital dynamometers. Here are the main types:
- Digital dynamometers: they are the most commonly used measuring instruments in all areas due to the ease of reading measurements on the LED or LCD display. NBC produces dozens of models suitable for every need, equipped with a port for connection to a PC and for remote control.
- Spring dynamometers: these are the simplest dynamometers and are used in schools, laboratories, or sometimes in industries for quick measurements. The loads typically do not exceed 50 kg.
- Mechanical dynamometers: they are used in military or agricultural settings, in case it is impossible to recharge the batteries.
- Hand-held dynamometers: they are needed in the medical field to check the functionality of limbs.
- Luggage dynamometers: these are used by airlines that often impose a limit on luggage. We therefore find them at airport check-ins.
