0.1 μm digital dial indicator – SA029M-02EX

The 0.1 μm digital dial indicator is a solution designed for extremely high-level comparative inspections, where extremely small variations must be detected with higher sensitivity than a 0.001 mm digital dial indicator. With a 0.1 μm resolution, equal to 0.0001 mm, this model belongs to the category of ultra high-accuracy digital dial indicators, intended for inspections where even minimal deviations must be clearly detected and managed.

The measuring range is 2 mm, with ±0.5 μm accuracy and 0.3 μm repeatability. This configuration makes it particularly suitable for applications where a large stroke is not required, but where the ability to monitor micro variations continuously and reliably is essential. It is therefore an excellent solution for high-quality inspection departments, measuring stations, dedicated fixtures and dimensional inspections with very tight tolerances.

From a functional point of view, this instrument combines the numerical reading of the LCD display with an additional analog display, offering the operator both the immediate digital value and a visual indication of measurement trend. This dual display is especially useful when combining the convenience of direct reading with the fast interpretation typical of an analog display.

The ABS/INC mode allows operation in both absolute and incremental measurement, while the zero setting in any position makes it possible to define the reference point directly where required. In addition, the mm/inch conversion is useful when measurements must be managed in different units or when adapting the inspection to different technical specifications.

One of the most interesting aspects of this model is the possibility of using Min/Max functions and tolerance setting. In this way the instrument not only displays the measured value, but also helps the operator immediately understand whether the measurement is within the specified limits. This function is particularly useful for repetitive inspections, batch control and applications where results must be interpreted quickly.

For integration into quality control processes, the instrument includes a USB and wireless interface, with the possibility of data transmission and wireless report printing. The presence of a memory capable of storing up to 999 readings also allows measurement collection and archiving, making the instrument suitable when data traceability is important in quality control.

The rotating display makes reading easier during non-vertical measurements, while the LED alarms help the operator quickly interpret the inspection result. The IP54 protection also makes this instrument suitable for use in workshops and production departments where dust and liquid splashes may be present. The inductive measuring system completes a configuration intended for high-accuracy inspections.

Optional replacement contact points are available on request, useful for adapting the contact point to the geometry of the part and to the type of inspection required. This allows the instrument to be configured for surfaces, seats, grooves, cavities and contact points requiring a different setup from the standard one.

From an application point of view, the 0.1 μm digital dial indicator is an excellent choice for users looking for an instrument capable of combining ultra high accuracy, immediate reading, tolerance management and data transmission. It is particularly suitable when inspections must be quick to interpret, documented and consistent with advanced production and testing requirements.

FAQ – 0.1 μm digital dial indicator

What is a 0.1 μm digital dial indicator?
It is an instrument designed for ultra high-accuracy comparative inspections, suitable for detecting extremely small deviations with 0.1 μm resolution.

What is a 0.1 μm digital dial indicator used for?
It is used to verify micro variations relative to a reference, especially in dimensional inspections with very tight tolerances.

What is the difference between a 0.1 μm digital dial indicator and a 0.001 mm model?
The main difference is the reading sensitivity: the 0.1 μm model can detect even smaller variations than a standard 0.001 mm digital dial indicator.

What measuring range does this model have?
The measuring range is 2 mm.

What does 0.1 μm resolution mean?
It means the instrument can detect variations of one ten-thousandth of a millimeter, equal to 0.0001 mm.

What are the declared accuracy and repeatability values?
Accuracy is ±0.5 μm, while repeatability is 0.3 μm.

What is the advantage of the combined digital and analog display?
It allows both immediate numerical reading and visual monitoring of measurement trend, useful in comparative inspections.

What are the ABS and INC modes used for?
They allow operation in both absolute and incremental measurement, depending on the inspection requirements.

Why is the Min/Max function useful?
It helps quickly monitor extreme values reached during inspection, especially in repetitive or dynamic controls.

What is the benefit of tolerance setting?
It allows the operator to define acceptance limits and immediately understand whether the measured value is within the specified range.

What is the mm/inch conversion used for?
It allows quick switching between metric and imperial units when inspection specifications require it.

When is the rotating display useful?
It is useful during non-vertical measurements or when frontal viewing would be less convenient.

Can this indicator transmit data?
Yes, it has USB and wireless interface, with data transmission and wireless report printing.

How many readings can it store?
