One of the main elements of industrial weighing equipment are strain gauges, as well as their accessories: tension cables and mounting units. Actually, strain gauges are at the heart of the mechanism of any electronic weighing equipment. Thanks to the method of using strain gauges, electronic weighing equipment, unlike mechanical weighing equipment, has become much more functional, more accurate and smaller in size. The electronic system made it possible to move to a qualitatively new level of work and fully automate control and measurement processes.
There are several types of strain gauges:
- Single point They allow you to create weighing systems. They are used in dosing and packaging equipment, as well as in constructions of platform scales with a small load on the platform.
- Cantilever (shear cantilever beam) are used as sensitive elements in scales and weighing systems with a total net weight of 5-7 tons.
- S-shaped (tension-compression beam) are intended for suspended bunker scales. Equipment installation and start-up time is reduced by equipping the sensors with hinged suspensions. Such sensors work on the principle of converting the mechanical force of tension / compression into a proportional electrical signal along the axis of symmetry of the sensor.
- Cylindrical ones work by converting mechanical deformation into a proportional electrical signal during compression. They are used in the manufacture of new or modernization of old automobile, wagon or multi-ton bunker scales. And also in control and measuring equipment and test stands.
- High temperature. Strain gauges of this type are necessary for measuring weight in conditions with high temperature, therefore they are most often used in metallurgy, as well as for weighing in extreme industrial conditions.
- Stainless steel sensors, as a rule, are designed for long-term operation and are used in aggressive environments, such as the food or chemical industry.
- Strain gauges are designed to work in harsh conditions and are necessary as measuring elements in a telecommunications network with high mechanical loads.
The manufacturer Esit offers a wide range of strain gauges and accessories for it, which have excellent operational characteristics. It is worth noting that many models of strain gauges of this brand perform several functions at the same time: measurement of weight, pressure, force, control of acceleration, movement. This is facilitated by the excellent technical characteristics of the devices and some other features that a brief review will help reveal.
