Large-Dimension Measuring Instruments
Configure TESA UNIMASTER instruments for large internal or external dimensions. Select extensions, contacts and the reference arrangement around the component and required measurement method.
What can you measure?
Large external dimensions
Measure external spans or diameters using the specified contact arrangement. Check alignment, support and handling of the complete assembly.
Deviation from a reference dimension
Use a defined reference for comparative measurement. Establish a repeatable contact and alignment method for the large component.
Models and measurement options
| Family / option | Configuration | Selection notes |
|---|---|---|
| UNIMASTER, metric | Direct or comparative internal/external measurement | Choose the required configuration from the actual dimension and access. |
| UNIMASTER extensions | Assembled measuring-length coverage | Specify the complete range and combination required. |
| Measuring bolts | Contacts for the measurement arrangement | Match contact geometry and size to the workpiece. |
| Setting standard | Reference for the selected setup | Define reference size, setting method and documentation. |
This comparison describes product families and configurations. Confirm the exact range, permissible error, accessories and documentation with the selected part number. Display resolution alone does not state measurement accuracy.
What to consider before choosing
Span and access
Provide minimum and maximum dimensions, internal/external measurement and the available contact positions.
Alignment and support
Describe how the workpiece and instrument can be supported. Include handling clearance and environmental conditions.
Reference and tolerance
Specify the reference arrangement and required dimensional tolerance. Review the assembled system’s performance.
Frequently asked questions
Can UNIMASTER measure both inside and outside dimensions?
TESA lists UNIMASTER for direct or comparative internal and external measurement. Specify the contact and extension configuration for the actual task.
Does adding an extension automatically cover my part?
Reach alone is insufficient. Review contact seating, alignment, support and the complete assembly against the required dimension and tolerance.
Where are the VERIBOR instruments listed?
VERIBOR bore instruments are grouped with Bore Gauges & Inside Micrometers so customers can compare internal-diameter methods together.
Which details are needed for a large-dimension quotation?
Send the drawing, dimension limits, tolerances, contact access, part support, temperature conditions and preferred direct or comparative method.
