Thickness measurements

The thickness measurement can be done with contact and non-contact technologies.

Contact technologies are mainly used for static measurements, for measurements in the metrological laboratory or in low speed applications.

Non-contact measurements, mainly based on LASER technology, is a reliable and consolidated technique for measuring small, medium and large thicknesses but above all on moving or easily deformed objects.

Industrial LASER distance meters

Industrial laser distance meters are useful and accurate tools for measuring theremote and non-contact moving in industrial environments. These devices use a beam of laser light to measure the distance between two points accurately and reliably, with an accuracy of up to tenths of a millimetre.

One of the most important features of industrial laser distance meters is theirs ability to work in long range and in difficult environmental conditions. Thanks to their precision, these instruments can be used in a wide range of applications, including those that require extremely accurate measurement, such as civil engineering, quality control and industrial manufacturing.

Linear transducers

Il linear displacement transducer it is a device used to measure small displacements, usually less than one metre, and very often with very high precision and resolution.

The linear transducers have high precision and repeatability even in harsh working conditions and in the presence of contaminants.

Linear position transducers are robust and reliable, created specifically for the industrial sector, they ensure a long operational life. They offer measuring ranges from 0,2mm to 10mm in high accuracy versions and up to 300-1000mm in standard accuracy versions.

Economical, miniaturized, pressurized, spring-loaded, with or without built-in electronics versions are available. All linear transducers can be connected to amplifiers with analogue, RS232, USB or fieldbus outputs.

Ultrasonic thickness gauges

Ultrasonic thickness gauges are used for measure the thickness of materials by accessing from only one side of the wall using ultrasonic waves.

When an ultrasonic wave is sent through the material, this signal is reflected from the back wall of the material and received by the feeler gauge probe. The delay between sending and receiving the signal can be used for calculate the thickness of the material.

To be able to measure the thickness of a wall with an ultrasonic meter, the material must be homogeneous and compact. Almost all metals are suitable for measurement with an ultrasonic thickness gauge, as well as other materials such as glass, plastics and even some types of rubber.

The ultrasonic thickness gauge is used in preventive maintenance, in ordinary maintenance, during non-destructive tests or for the acceptance of materials in the production phase.

The choice of the ultrasonic meter must be based on the application to be addressed. You can choose instruments with a generic probe, suitable for many applications, or instruments with interchangeable probes and that can be adapted to specific applications (high temperature, presence of paints, large measurement area, materials particularly difficult to measure because of medium and low density).

Comparators

The comparator is a measuring instrument used for measurements of linear displacement, oscillations, straightness, form errors, positions and in some cases vibrations.

The comparator uses a linear transducer, integrated in the measuring instrument, and a display to indicate the displacement of the rod. The end of the rod, called the probe, is in contact with the surface of the object being measured.

The type of probe can be chosen based on the use and shape of the contact point. Point, ball, plate, chisel or rolling bearing probes are available.

The comparators offered by INNOVACHECK are made with miniaturized indicators and with very low consumption, so much so that they can be easily powered by a common button cell battery. The comparator displays are normally made with a resolution of 0,01 mm (hundredths), 0,001 mm (thousandths). Some special models of comparators can also reach sub-micron resolutions.

Fork thickness gauges

When an ultrasonic wave is sent through the material, this signal is reflected from the back wall of the material and received by the feeler gauge probe. The delay between sending and receiving the signal can be used for calculate the thickness of the material.

Triangulation LASER sensors

Triangulation laser sensors are non-contact measuring instruments widely used in various industries. These sensors adopt triangulation technology for measure the distance between the sensor and the object surface, thus allowing to obtain with high precision the measurements of displacements required by the production processes.

La triangulation technology it is based on the emission of a laser beam which is projected onto the object surface and reflected towards the sensor.

Laser triangulation sensors offer many advantages over traditional measuring instruments. First, they allow you to make non-contact measurements, which means that there is no risk of damaging the object surface that is being measured. Also you can measure moving or easily deformed objects. Furthermore, the triangulation laser sensors are particularly precise and they can detect even small displacements with an accuracy of a few microns.
