The long stroke digital dial indicator is a solution designed for comparative inspection of linear displacement when the travel to be monitored is greater than that of standard digital dial indicators. In this series, the 50 mm measuring range makes the instrument particularly useful in applications where it is not enough to monitor small local variations, but where a longer movement must be followed while maintaining clear and immediate reading.
The operating principle remains the same as traditional dial indicators: the contact point touches the part or the element to be checked and the displacement is converted into a readable value shown on the LCD display. Compared to analog models, the value appears directly on the screen, without the need to interpret the pointer position. This makes inspections faster, especially during repetitive inspections or in stations where multiple operators use the same instrument.
The main feature of this model is precisely the long stroke, making it suitable for checking level differences, larger displacements, dimensional variations, slide movements, adjustments and inspections on mechanical elements working with greater travel. It is therefore an interesting solution whenever a standard dial indicator does not provide sufficient measuring range.
The series is available in two versions to better match the required inspection sensitivity. The 0.01 mm version offers practical reading for general workshop inspections, while the 0.001 mm version provides finer reading for more detailed inspections. This allows the most suitable configuration to be selected according to the type of verification required.
From a functional point of view, this indicator integrates several useful features for daily operation. The large display simplifies reading, the zero setting in any position allows the reference to be set directly at the desired point, and the mm/inch conversion enables quick switching between metric and imperial units according to the application requirements or drawing specifications.
In practical use, long stroke digital dial indicators are well suited not only for standard workshop inspections, but also for tooling departments, test benches, inspection stations and measuring devices. The combination of wide measuring range and digital reading makes them particularly useful when extended displacement must be monitored without giving up the convenience of direct display reading.
Upon request, optional contact points are available to adapt the contact point to the geometry of the part and the inspection type. This allows the indicator to be used more flexibly on surfaces, cavities or contact areas requiring different configurations compared to standard applications.
From an application perspective, this instrument is an interesting solution for users looking for a digital dial indicator capable of combining wide measuring range, immediate reading and versatility of use. It is particularly suitable when extended movements or larger dimensional variations must be monitored while maintaining simple data management and a configuration suitable for daily workshop and quality control use.

FAQ – Long stroke digital dial indicator
What is a long stroke digital dial indicator?
It is a digital display dial indicator designed to monitor linear displacement over a wider measuring range compared to standard models.
What is a long stroke digital dial indicator used for?
It is used to verify dimensional differences, movement and displacement when the travel to be monitored is greater than normal.
Why choose a long stroke model?
Because it allows wider displacement to be monitored without changing instrument or giving up the convenience of digital reading.
What is the difference between the 0.01 mm and 0.001 mm versions?
The 0.01 mm version provides hundredth reading for general inspections, while the 0.001 mm version provides finer thousandth reading for more detailed inspections.
What advantage does the digital display offer in practical use?
It allows values to be read directly, quickly and more uniformly, especially during repetitive inspections.
What does zero setting in any position mean?
It means the zero reference can be set at any desired point so that displacement from that reference can be read immediately.
What is the mm/inch conversion used for?
It allows rapid switching between metric and imperial readings, useful when working with different measurement units.
What is the measuring range of this series?
The measuring range available is 50 mm.
In which situations is it more useful than a standard dial indicator?
It is more useful when monitoring longer movement, larger level differences or dimensional variations requiring greater travel.
Is this indicator only suitable for mechanical workshops?
No, it can also be used on test benches, inspection stations and measuring devices where larger linear displacement must be monitored.
Are optional contact points available?
Yes, optional contact points are available on request to better adapt the contact to the shape of the part and the type of inspection.
Who is this long stroke digital dial indicator intended for?
It is intended for users looking for an easy-to-read instrument with wide measuring range, suitable for comparative inspections on extended movements or larger dimensional variations.
