KLT is a family of thickness gauges based on the well known principle of laser triangulation with two sensors mounted at the opposite sides of the target material. Each sensor measures the position of the relevant surface along the optical axis by means of a laser beam observed through an angled optical system. Material thickness is calculated from the combination of the position of the two surfaces , given the distance between the two sensors. The measure is performed when both material surfaces are running inside the measuring range. Laser sensors are mounted inside heavy-duty mechanical frames, typically in form of C-frames or as separate heads. The measured values are available in digital and graphic form on the operator panel with immediate out-of-tolerance signal. Additionally, a control report is automatically generated and sent to LAN PC through Ethernet connection.
A wide range of options and accessories, standard and customized, complete the system configuration for each application case.
Customer can choose among various standard thickness gauges models with micrometer accuracy and measuring ranges up to 80 mm. Special models upon request.
SINGLE POINT THICKNESS GAUGES:
KLT-100 and KLT-1000 series
Single point KLT thickness gauges are the ideal solution to measure both narrow and wide strips nearby the edge or up to the center line on all metal processing lines. Measuring heads can be installed in fixed position or moved from parking to measuring point by means of linear axis with manual or motorized travel.
MULTI-POINT THICKNESS GAUGES:
When it is necessary to measure more points at the same time (for example on both edges or at center line + edges) the KLT laser thickness gauges are equipped with multiple heads, mounted in fixed position or moved from parking to measuring point by means of manual or motorized linear axis.
SCANNING THICKNESS GAUGES:
These gauges continuously move the measuring head back and forth along full material width and provide the measure of the thickness profile in addition to the thicknesses at edges and center line.
Thickness gauges XLT are non-contact measuring systems to be applied on flexible materials with a surface running in contact of a reference roll: material thickness is calculated as the measured difference between the position of the upper material surface and the roll surface.
One of two measuring technologies can be choosen in function of the working conditions and of material type. The first is based on the principle of optical projection of the material’s edge between a transmitter and a receiver. The second measures the surface position by laser triangulation. In both cases, measurement is performed with a totally safe method, with working distance high enough to avoid any contact with material and in the total absence of harmful radiation for operators and for the environment.
All the optoelectronic components are integrated into a heavy-duty mechanical frame, typically in fork-type construction, of easy configuration and equipped with a cleaning system for optical windows. The measuring head can be mounted fixed in one or more points, or on a scanning system that goes through the entire width of the material in a continuous cycle.
The measurement results are visible in digital and graphic form on the operating panel with immediate display of out of tolerance on five levels. Moreover, a control report is transmitted to external PC connected through Ethernet interface to local LAN.
A wide range of standard and custom accessories and options completes the system configuration in any specific application case.
Models with hundredths or thousandths precision and with measuring range up to 50 mm are available. Special models on request.
UMT thickness gauges working principle is based on special ultrasonic measuring sensors. It is a non-contact measuring technology which allows safety operation, without hazard radiations. Depending on material type or installation, thickness measurement can be done either with two opposite sensors or with single sensor. In this last case, material must be in contact with a reference roll or plane. Each sensor measures the distance of the relevant material surface by measuring the ultrasonic wave propagation time from the sensor to the material and back.
Thickness is calculated from the distance combination of the two surfaces, given the distance between the two sensors or between single sensor and reference plane.
Measure is taken when both material surfaces are running inside the measuring range.
