Product introduction

The F series is based on the principle of laser diffraction (Fresnel diffraction), with a simple structure that provides stable and accurate measurements over a long service life.

With an extremely short exposure time of 0.5μs, measurement remains accurate even on vibrating objects. A fast sampling frequency of 10kHz enables detection of lumps and necks on the object. Thanks to the motor-free and lens-free internal design, there is no calibration requirement or related maintenance, which largely reduces operation difficulties and improves user convenience.

Available in 2-axis and 4-axis configurations, the devices cover ranges from 0.2 to 10mm and 0.5 to 30mm. They are applicable to the measurement of both transparent and non-transparent objects, such as electrical wires and cables, steel wires, enamelled copper wires, medical hoses, 3D filament, etc. The 4-axis devices feature a smaller blind area and more comprehensive sampling data to reflect the wire's actual status, making them highly suitable for applications with strict ovality requirements.

Key Features

Measurement is still accurate on vibrating objects

Extremely short exposure time, capable of capturing object images without any blur or shadow, ensuring accurate measurement.

4-axis measurement with less blind area

The figure explains the relationship between the measurement result and the number of axes. The more axes there are, the smaller the blind area becomes, resulting in more accurate measurements.

Sampling frequency of 10KHz

Sampling frequency can reach up to 10kHz due to no motor running speed limitation, which enables getting more information about the object under measurement.

High stability

Thanks to no moving parts inside, there is no measurement deviation caused by long-term use.

Note:
(1)Set average time to 0.1s and measure the ±2σvalue of the φ1mm round rod at the measurement area center;
(2)Set average time to 0.1s and measure the ±2σvalue of the φ10mm round rod at the measurement area center;
(3)Move φ1mm round rod in the measurement area and conduct measurement error;
(4)Move φ10mm round rod in the measurement area and conduct measurement error;
(5)set defect measurement average time as 0ms, the minimum arc defect length which cannot be missed at the measurable area;
(6)Industrial communication module and PI feedback control module is installed before ex-factory,so notify the demand before placing an order.

Frequently Asked Questions

Answers to frequently asked questions about Laser Micrometer

Q Can outer diameter and ovality be measured simultaneously? ⌄

Yes. Several DALA models support both outer diameter and ovality measurement, including the E3 ultra-fine wire gauge, F Series, TL-2000 Series, and TL-3000 Series.

Q Can 3D printing filaments of different colors be measured for diameter? ⌄

Yes. DALA diameter gauges can measure 3D printing filaments in different colors.

Q Can DALA’s diameter gauge be linked with an extruder for automatic adjustment? ⌄

Yes. It can be integrated with the extruder through PI control, with adjustment signals output via analog signals or communication interfaces.

Q Which diameter gauges are commonly used for 3D printing filament? ⌄

Both DALA’s TL Series and F Series are suitable for 3D printing filament applications.
