Accura Thickness Gauge
The Industry Standard In PC-Based Gauging
Accura Thickness Gauge
Fast | accurate | dependable | Cost-Effective
The Accura Gauge was born from an industry request to create a cost-effective, high-speed, non-contact gauge system, based on off-the-shelf industrial PC technology. From the first installation the Accura has exceeded customer’s expectations. The system maximizes the use of top quality, off-the-shelf components, including a robust industrial PC. The gauge software was specifically developed by GGC engineers to take advantage of high speed processors available in today’s industrial PCs. The resultant gauge system is extremely fast, well beyond the requirements of most closed-loop mill control systems. Accura gauges are installed all over the world on rolling mills and process lines. This gauge is suitable for measuring the thickness of metals (ferrous and non-ferrous), plastics, ceramics, and many other types of materials.

Accura Thickness Gauge Specifications
MEAN RESPONSE TIME
“The mean time after a step variation in the measured quantity until the output signal reaches a specified percentage of its final mean value for the first time. For this standard, 63.2% of the step change shall be the specified percentage.”
(IEC 1336, 1.3.24.1)
Response Time
<2mS per Test Point A (IEC 1336, 1.3.7.1)
STATISTICAL NOISE
“Variation of the output signal under reference conditions, while all influence quantities are held constant and the detector is in an irradiated condition.”
(IEC 1336, 1.3.22)
Statistical Noise
@10mS the 2σ variation = ± 0.12%
ACCURACY
“Degree of conformity of an indicated value to a recognized standard value, or ideal value.”
(IEC 1336, 1.3.14)
In the case of Thickness Gauges, the standard value is usually a precision master (internal or external) on which the gauge has been standardized. Accuracy is usually expressed as a percentage of the nominal thickness being measured.
Accuracy
The nominal 2σ = ± 0.1%, not better than ± 0.2μm
DRIFT
Drift is expressed as a percentage of the nominal thickness being measured.
Short Term ~1 hour
≤ ± 0.050% from the set thickness,
not better than ± 1μm
Long Term ~8 hours
≤ ± 0.1% from the set thickness,
not better than ± 2μm
REPRODUCIBILITY
“Closeness of agreement among a number of consecutive measurements of the gauge output signal for the same input and under the same operating conditions.”
(IEC 1336, 1.3.15)
Reproducibility
≤ ± 0.1% from the set thickness,
not better than ± 5μm
Repeatability
≤ ± 0.050% from the set thickness,
not better than ± 1μm
LINEARITY
The closeness to which the actual calibration curve approximates a straight line.” (IEC 1336, 1.3.26)
Linearity ≤ ± 0.05% from the set thickness, not better than ± 1μm
