that's our servicesAs an essential tool in the industrial field, industrial endoscopes play a very important role in equipment internal inspection and mechanical maintenance. What issues do purchasing and technical personnel of industrial enterprises need to pay attention to when choosing industrial endoscopes?
Inspection requirements:
It is necessary to clarify the type of equipment to be inspected, the internal structural characteristics and the channel size. For example, the inner diameter of the pipeline determines the diameter range of the endoscope probe. For complex curved channels, you need to choose an endoscope with good flexibility.
Determine the purpose and requirements of the inspection, such as conventional appearance inspection, defect detection or precise dimensional measurement. Different purposes have different requirements for the imaging quality and measurement accuracy of the endoscope. If it is used for measurement, you need to pay attention to the measurement accuracy and measurable range of the endoscope; if it is to find tiny defects, you need to choose an endoscope with a close focus and small depth of field.
Working environment:
Temperature range: Some industrial environments have high or low temperatures, such as high-temperature furnace internal inspection or low-temperature cold storage equipment inspection. You need to choose an endoscope that can adapt to the corresponding temperature range to ensure that the instrument works normally and will not be damaged by temperature changes.
Humidity and corrosiveness: In a humid environment or one with corrosive gases or liquids, such as chemical pipelines and marine engineering equipment inspection, the endoscope should have good waterproof and anti-corrosion properties, and its shell and internal parts should be able to withstand harsh environmental conditions.
Electromagnetic interference: In places with strong electromagnetic fields, such as around power equipment, the endoscope's anti-electromagnetic interference capability should be considered to avoid interference with the instrument and affect image quality or normal operation.
Technical parameters:
Imaging quality
Including image resolution, field of view, depth of field, object distance, etc. Higher resolution can show tiny defects more clearly.
Field of view and depth of field
The field of view determines the size of the observation range. A large field of view can cover a wider area, but there may be certain image distortion problems. Depth of field affects the ability to clearly image objects within different distances, which is more important for detecting objects with different depth levels. When purchasing an endoscope, you need to refer to the distance at which the object is observed to select an endoscope with corresponding parameters.
Focusing mode
The focusing modes include fixed focus and automatic zoom. Fixed focus refers to fixing a focal length parameter value, which is suitable for the detection of fixed scenes. Zoom is the camera automatically adjusting the focal length according to the scene environment, and the focal length range is large. Fixed focus can set the best clear focal length according to the actual use scene, so as to achieve better imaging effect. The wide range of zoom is suitable for scenes of different distances, but due to the certain focusing time when the camera automatically zooms the scene, the image cannot be obtained in time, and the clarity of the details is not as good as fixed focus.
Insertion tube characteristics
It is also necessary to pay attention to parameters such as the diameter, length, flexibility and bending radius of the insertion tube. The smaller the diameter, the more it can adapt to narrow spaces, but it may limit the integration of some functional components; the length must meet the detection depth requirements; the insertion tube with good flexibility and small bending radius can be conveniently operated in complex curved channels.
Type of wire
Common wires for endoscopes include soft wires, hard wires, and hard tubes. The use requirements of different materials are different. Soft wires can better extend into various internal spaces due to their softness. Hard wires can form a fixed angle due to the hardness of the wire material, which is suitable for use in pipes that need to be viewed upward. Hard pipes are mostly made of stainless steel, which has better corrosion resistance, and hard pipes are not easy to shake, so clear images can be obtained better.
Light source brightness and type
Sufficient light source brightness is the key to ensuring clear imaging. Depending on the detection environment, different brightness levels and light source types may need to be selected.
Additional functions
Measurement function: As mentioned above, if accurate measurements are required during the detection process, an endoscope with measurement function and measurement accuracy that meets the requirements should be selected.
Image storage and transmission: Consider whether the detection images and data need to be stored for subsequent analysis and report generation. Some endoscopes support direct connection to computers or other storage devices for data transmission and storage, and some also have wireless transmission functions to facilitate remote monitoring and data sharing.
Portability: For situations where detection operations need to be performed in different locations, such as field equipment maintenance or on-site repairs, portable industrial endoscopes are more advantageous. They are light in weight, small in size, and easy to carry and operate.
