RIKEN RFL-1502
The RIKEN RFL-1502 has a nominal length of 150 mm.
It may be suitable when a shorter instrument is required for an approved machine reference surface.
RIKEN RFL-2002
The RIKEN RFL-2002 has a nominal length of 200 mm.
It may be preferred when a longer suitable measuring surface is available.
Which Model Is More Accurate?
Both models have the same specified sensitivity.
The longer RFL-2002 is not automatically more accurate than the RFL-1502.
Accuracy depends on the instrument's measurement characteristics and relevant calibration results, not simply its physical length.
4. What Does 0.02 mm/m Sensitivity Mean?
One of the most important specifications of the RIKEN RFL-1502 and RFL-2002 is 0.02 mm/m sensitivity.
This describes an inclination equivalent to a height difference of 0.02 mm over a horizontal distance of one metre.
Inclination Calculation
Height Difference (mm) = Inclination (mm/m) × Horizontal Distance (m)
Equivalent Inclination Table
Horizontal DistanceHeight Difference at 0.02 mm/m100 mm0.002 mm150 mm0.003 mm200 mm0.004 mm500 mm0.010 mm1,000 mm0.020 mm
For example:
0.02 mm/m × 0.2 m = 0.004 mm
This means that an inclination of 0.02 mm/m is mathematically equivalent to a height difference of 0.004 mm over 200 mm.
These figures illustrate slope.
They are not guaranteed accuracy values, instrument calibration uncertainty values or machine installation tolerances.
Sensitivity vs Accuracy
Sensitivity describes the instrument's response to inclination changes.
Accuracy concerns the closeness of a measured result to the reference value.
Measurement Uncertainty describes the uncertainty associated with a measurement result.
Understanding these differences helps prevent incorrect instrument selection.
5. Precision Flat Level vs Standard Spirit Level
A common question is whether a standard spirit level is sufficient for CNC machine installation.
The answer depends on the required measurement sensitivity and machine manufacturer's procedure.
Standard Spirit Level
General-purpose spirit levels are commonly used for construction and ordinary installation work.
Their sensitivity depends on the specific model.
RIKEN Precision Flat Level
The RIKEN RFL-1502 and RFL-2002 feature 0.02 mm/m sensitivity.
They are intended for precision machinery applications.
