What is the accuracy of different laser thickness gauges?
Laser thickness gauge is a precision equipment based on the principle of laser detection to achieve thickness measurement. According to different detection forms and characteristics of the measured object, it is divided into various types. Let's take a brief look at the detection accuracy of different types of laser thickness gauges.
Let’s first understand the classification of laser thickness gauges, according to the composition of the measuring head: a built-in laser displacement sensor, two laser displacement sensors facing each other; according to the detection method: contact thickness gauge, non-contact thickness measurement Instrument; according to the number of probe groups: single-point thickness gauge, multi-point thickness gauge (2, 3, 4, 5...); according to sensor: laser displacement sensor, laser distance sensor, two-dimensional laser measurement Sensor, laser position sensitive sensor; according to the detection method of wide plate: scanning thickness gauge, multi-point thickness gauge.
Detection accuracy of some laser thickness gauges:
The HW01-DG120 single-point thickness gauge has a built-in high-precision laser displacement sensor, which measures the height of the stacked items on the pallet with the pallet as the reference plane. Scope of application: machinery, chemical industry, food, etc. The measurement accuracy of the measurement range of 0 ~ 120mm can reach 0.1mm.
The measurement accuracy of the following thickness measuring devices is: the measurement range of 0-20mm reaches ±0.03mm, the measurement range of 0-30mm reaches ±0.03mm, and the measurement range of 0-50mm reaches ±0.12mm.
HW01—SG series single-point thickness gauge uses two upper and lower laser displacement sensors facing each other to measure the thickness of the edge of a disc-shaped object. The disc is placed on the tray driven by the stepping motor, and the tray rotates once by clicking the measurement button, and the thickness of the upper edge of the entire circumference of the measured object can be measured. Applicable industries: measurement of disc-shaped workpieces such as machining and automobiles.
The single-point and multi-point thickness gauges adopt a C-shaped frame structure as a whole, and two upper and lower laser displacement sensors are installed on the C-shaped frame to measure the thickness of a point. The thickness gauge is equipped with a single-chip computing system, and the thickness data changes can be observed in real time during measurement. Applicable industries: steel rolling, non-ferrous metals, rubber, plastics, wood boards, etc.
The waterstop three-point thickness gauge can measure engineering waterstops of various cross-sectional shapes. The device has built-in 3 pairs of laser displacement sensors to measure the thickness of 3 points of the waterstop, and the sensor can scan along the width direction of the waterstop to measure the thickness on each width coordinate. The measurement accuracy of the measurement range of 0-30mm reaches ±0.05mm, and the measurement accuracy of the measurement range of 0-50mm reaches ±0.15mm.
The laser sensor of the contact thickness gauge is a contact sensor. When the thickness measurement range is 1-10mm, the measurement accuracy is ≤±0.01mm. Scope of application: The equipment is mainly used for static measurement of hard plates such as normal temperature steel plates and non-ferrous metals, or intermittent thickness measurement with short stop stations on the production line. In addition, there are various types of contact thickness gauges, such as: when the thickness measurement range is 10-120mm, the measurement accuracy is ≤±0.05mm; when the thickness measurement range is 1-10mm, the measurement accuracy is ±0.02mm.
There are many types of laser thickness gauges, and the classifications can be interoperable and can be customized according to the needs. The above introduction is the precision size of the commonly used equipment. Other measurement ranges and measurement accuracy can also be customized according to the needs. It is a very flexible measurement device.
