DITRON 0.002mm Lever Dial Indicators | DT832 DT840 DT940 DT1040 Comparison Malaysia

Choosing a Fine-Resolution Lever Dial Indicator


The DITRON DT832, DT840, DT940 and DT1040 Lever Dial Indicators are designed for small displacement checks, alignment, runout inspection and comparative measurement.


All four models have a listed measuring range of 0–0.2mm, resolution of 0.002mm and accuracy of ±0.004mm. The main catalogue differences are dial diameter and dial outer ring material.


For machining workshops, toolrooms and quality control teams in Malaysia, these indicators provide a finer reading increment than a 0.01mm lever indicator. Their shorter measuring range requires careful positioning and sufficient working movement around the reference point.


KEY FEATURES


0.002mm Resolution


The dial graduation is 0.002mm, equivalent to 2µm. This allows operators to observe smaller position changes during comparative inspection.


±0.004mm Listed Accuracy


The catalogue specifies an accuracy of ±0.004mm, equivalent to ±4µm, for all four models.


Resolution and accuracy are different specifications. These indicators should not be described as having ±0.002mm accuracy.


Lever Contact Arrangement


A pivoting stylus follows the workpiece surface. This arrangement can help reach features where a straight plunger indicator is difficult to position.


Full Gear Transmission System


The catalogue specifies a full gear transmission system for transferring stylus movement to the dial indication.


Automatic Measuring Direction Reversal


A mechanism for automatic reversal of measuring direction is listed. Follow the operating instructions when changing contact direction, and verify the reference after repositioning.

WHICH MODEL SHOULD YOU CHOOSE?


DT832 for a Smaller Dial Envelope


The DT832 has a 32mm dial and metal outer ring. Consider it where available space limits the size of the dial face.


Confirm the complete body and mounting dimensions because dial diameter alone does not establish installation clearance.


DT840 or DT940 for a 40mm Metal-Ring Dial


Both models have a 40mm dial, metal outer ring and the same listed measuring specifications.


The supplied page does not explain all construction differences between them. Confirm the exact configuration, holder compatibility and included accessories before ordering.


DT1040 for a 40mm Plastic-Ring Configuration


The DT1040 combines a 40mm dial with a plastic outer ring. Its listed range, resolution and accuracy match the other three models.


A larger dial or different ring material does not change the stated accuracy on this catalogue page.


0.002MM OR 0.01MM LEVER INDICATOR?


A 0.002mm lever indicator provides a finer graduation for observing small changes. It is useful when the inspection task needs more reading detail and the complete setup can support it.


A 0.01mm indicator may be sufficient for checks with less demanding reading requirements. Select according to the tolerance, expected displacement and required travel.


Fine resolution alone does not establish measurement suitability. Stand movement, stylus angle, surface condition and reference quality also affect the result.


TYPICAL APPLICATIONS


Fixture and Workpiece Alignment


Observe small changes while adjusting a fixture or accessible workpiece surface to a reference position.


Workpiece Centring


Compare readings around a suitable feature during centring operations, using an appropriate holder and setup.


Runout Inspection


Follow an accessible surface while a component rotates in a suitable inspection fixture.


The difference between the maximum and minimum readings gives the total indicated variation for that setup. Component support and alignment also influence the result.


Comparative Surface Checks


Observe differences in surface position as a supported component moves beneath the stylus.


Formal assessment of geometric tolerances requires an appropriate datum and measurement procedure.


These applications are relevant to engineering and manufacturing teams in Selangor, Penang, Johor and other industrial areas in Malaysia.


SETTING UP FOR CONSISTENT READINGS


1. Secure the holder.


Use a rigid mounting arrangement and check that the stand, arm and clamps remain stable.


2. Clean the contact surfaces.


Remove chips, dirt and deposits from the stylus tip, reference and workpiece.


3. Set the stylus orientation.


Follow the manufacturer’s recommended contact geometry. An unsuitable stylus angle can introduce measurement error.


4. Establish working movement.


Position the stylus with suitable initial deflection and enough movement for the expected variation. The listed range is only 0.2mm.


5. Establish the reference.


Set the reference indication against the selected datum or suitable master.


6. Repeat the measurement.


Repeat the contact or measurement cycle to assess consistency before recording the result.


Avoid forcing the stylus against the workpiece or using the indicator as a mechanical stop.


CARE AND ROUTINE CHECKING


Protect the stylus from impact and excessive deflection. Recheck the reference after changing the holder position, contact direction or setup.


If readings fluctuate, first inspect mounting rigidity, contact condition, vibration and workpiece support.


Persistent sticking, poor return or disagreement with a suitable reference warrants further inspection or calibration.


The supplied catalogue does not specify stylus length, measuring force, contact tip diameter, mounting dimensions or an IP rating. Confirm these details where they affect the application.
