NEXTSENSE is a global leader in producing and distributing revolutionary profile measurement solutions for trains and tracks. The non-contact measurement gauges, called CALIPRI, are based on advanced laser light section technology.

No matter who uses them, the parameters they gather will always be accurate, unaltered and free from fluctuations and assumptions. Moreover, the measured data is transferred digitally to desired databases, so that nothing can go wrong with the documentation of measurement results.

CALIPRI C4x: Multifunctional non-contact profile measurement device

The product family CALIPRI C4x enables the profile inspection of wheelsets and tracks without switching between different gauges. The multifunctional handheld device measures the profiles of wheels, brake discs, rails and switches on a non-contact basis, without the need to own systems for differently shaped measuring objects.

Recording a wide range of profile shapes with only one system substantially reduces purchase, calibration and training costs. A great number of software modules makes it possible to tailor one sensor to fit the given user situation exactly. A diversity of sensor sizes, such as for hard-to-access areas, allows further customisation.

CALIPRI Prime: Non-contact wheel profile measurement device

With the new sensor generation CALIPRI Prime, NEXTSENSE provides an attractive entry-level solution for highly precise inspection of wheels. The non-contact and handy measurement device enables highly accurate wheel flange measurements (flange height, width and qR).

In addition, CALIPRI Prime can measure wear values comprising wheel width, hollow tread and rollover. This device is the digital alternative to error-prone mechanical wheel profile gauges. CALIPRI Prime is very cost-efficient due to the focus on a single measurement task.

With CALIPRI, you can check profiles of various measurement objects in a similar way to tactile teaching. However, the non-contact operation of CALIPRI provides reliable and reproducible results in contrast to these contacting methods. The following benefits can be achieved with CALIPRI devices.

Reproducible measurement results without operator influence

The measurement is carried out on a non-contact basis. For the measurement, the user moves the sensor by hand over the object to be measured. The intelligent image processing system continually records segments of the object from various viewing directions and combines them.

Typical measurement errors due to tilted scanning, undefined measuring force or loop-sided application of gauges are ruled out by the patented CALIPRI technology. The distance and angle of the sensor to the measured object does not have to be kept exactly the same throughout the measurement process.

Non-contact profile measurements with the greatest precision

Confined spaces or difficult access pose no problem for CALIPRI. The ergonomically designed handheld sensors and the high-performance software allows for effortless and quick measurements. This means substantially reduced time expenditure, greater productivity and outstanding comfort.

Once the entire profile line of the object to be measured has been recorded, the data will be analysed and the resulting values will be visible on the CALIPRI display. Any overstepping of given tolerances is displayed immediately.

A multitude of interfaces with upgradeable analytical functions

For customised processing, CALIPRI measurement data can be stored and exported. By foregoing hand-written records and manual transmissions, the reports by CALIPRI are faultless and tamper-proof. Comprehensive analysis and reporting functions of the CALIPRI software result in a maximum of customisation of data processing.
