Having trouble inspecting the interior of machinery or narrow tubes that are not visible to the naked eye? Using a Borescope, also known by many as a snake camera, is a solution that makes work easier without having to spend time disassembling parts SCMA As a leader in measurement tools and automation systems, we summarize important information about what a Borescope is, so that readers can understand the working principle up to how to choose a Borescope camera for professional Borescope Inspection
What is a Borescope?
A Borescope is a device used to inspect narrow, dark, or hard-to-reach areas inside machinery and piping systems. It works together with a small fiber optic cable to send images back to the display screen. This type of snake camera helps technicians analyze cracks, corrosion, or foreign objects immediately. Using a Borescope saves both time and cost because it avoids the need to dismantle the workpiece.
How Borescope Works
The working principle of a borescope or an internal inspection tool relies on the integration of imaging and light technologies. The Borescope Inspection process has three main working steps as follows:
Illumination System
The probe of the borescope camera has a fiber optic cable or a small LED light installed at the tip of the cable. This system is responsible for sending light to dark or enclosed target areas to prepare for image capture. High-quality borescopes can adjust the brightness level to match the internal environment of the workpiece.
Optical/Imaging System
The tiny image lens works together with a high-quality sensor such as CCD or CMOS at the tip of the probe to capture details of the area to be inspected. This part of the borescope camera functions like an eye that can see internal abnormalities. During Borescope Inspection, the lens can clearly capture cracks or foreign objects.
Processing & Display System
The captured image signals are transmitted via the cable to the processing unit for display on a digital screen or application. Users of the borescope can view the internal machine in real-time. To fully answer the question of what a borescope is, it must also include the ability to record images for later report generation.
How many types of Borescopes are there?
Selecting a Borescope for industrial use in Thailand must consider the nature of usage and the area that needs to be inserted into. Snake cameras are divided into main types according to the characteristics of the probe shaft as follows
Rigid Borescope (Rigid Borescope)
This type of equipment has a straight rigid shaft and cannot be bent or flexed according to the environment. It is suitable for Borescope Inspection in straight and easily accessible areas. Common uses include inspecting drilled holes or simple cylinder bores
Flexible Borescope (Flexible Borescope)
The cable of this type of snake camera is highly flexible, allowing it to bend and navigate through curved pipes freely. This design helps overcome the challenge of accessing complex areas within machinery that rigid shafts cannot reach. Therefore, the use of flexible Borescopes is popular in pipeline system maintenance work
Video Borescope (Video Inspection Borescope)
This system has a small camera installed at the end of the cable to transmit digital video signals directly to the display screen. If you are unsure whether a Borescope can record images, this model is the perfect answer because it supports both still image recording and video recording for in-depth data analysis
Borescope Maintenance
Proper maintenance of the Borescope camera helps preserve image clarity and extends the lifespan of the sensor. Standard care procedures for the snake camera are important for operators as follows
Lens Cleaning
Dust or fingerprints on the camera head directly affect image quality during operation. Users should use a soft microfiber cloth dampened with specialized lens cleaning solution to gently wipe. Cleaning the Borescope camera after each use helps prevent the accumulation of dirt that may scratch the lens surface
Probe Cable Care
Although the snake camera cable is highly flexible, it can bend or be damaged if stored improperly. Operators must avoid bending the cable at sharp angles and should not coil it too tightly. Keeping the cable naturally curved helps prevent the optical fiber cable for Borescope Inspection from breaking
Proper Storage
Fragile electronic equipment should be stored in the shockproof box that comes with the unit. Preventing excessive moisture and high temperatures is crucial for extending the lifespan. If you wonder whether Borescope maintenance is complicated or not, simply storing it in a dry place already helps maintain the device's condition
Battery Management
Users should remove the battery from the unit immediately if they expect not to use the Borescope camera for a long period. Charging to an appropriate level helps maintain the battery cell condition and prevents premature degradation. Being prepared in terms of power ensures that the snake camera is always ready for emergency maintenance work
Borescope Usage
Using a borescope in conjunction with automated systems in factories elevates the standard of inspecting hard-to-reach small areas. SCMA Co., Ltd. has applied snake cameras to address industrial needs in a distinctive manner as follows
Automated Product Quality Inspection
Using a borescope together with image processing sensor systems such as Vision Sensors eliminates the risk of human error in decision-making. The device quickly and accurately scans for cracks or air bubbles inside the product. Applying snake cameras in automated production lines helps prevent non-conforming products from reaching customers.
Setting Standards and Traceability Inspection
The software system helps establish clear inspection criteria to determine whether the product meets the requirements. Recording images every time a borescope inspection is performed creates a database for traceability inspection. This system provides reliability to the production process according to international industry standards.
Maintenance and Fault Analysis
From the experience of the SCMA engineering team, we found that technicians can immediately inspect internal faults in pipes or engines without having to dismantle the product. If someone asks what the main benefit of a borescope is, the answer is the ability to quickly analyze the cause of the problem. Therefore, using a borescope is a crucial part of preventive maintenance work.
Advantages of Borescope
Choosing a borescope from SCMA helps engineers inspect complex areas efficiently. The main advantages of using a borescope in industrial work are as follows
Time and Cost Reduction
Users can immediately inspect wear or blockages inside machinery without stopping the production line for long. Working with a snake camera reduces the complicated steps of dismantling systems and requires a large number of laborers. Saving maintenance time results in factories reducing revenue loss during machine downtime
High Accuracy in Image Analysis
High-quality image sensors provide clarity at a level that allows clear visibility of small component details. Recording images for Borescope Inspection reports helps engineering teams analyze and build upon data accurately. Decisions based on real images help prevent errors even better
Durability and Flexibility in Environment
The body and cable of the borescope are specially designed to be durable against chemicals, water, or dust in factories. The camera cable is highly flexible and can freely bend to follow the shape of curved pipes. The strong design makes the snake camera a tool that meets heavy-duty tasks without any doubt
