An endoscope is a device for examining hard-to-reach spots. Its technical modifications are actively used in industry. At metallurgical enterprises, devices of this type are used for inspection of furnaces. Also, endoscopes provide an opportunity to look inside various tanks.
The main parameters of the devices include resolution, focal length, tilt radius and viewing angle. To understand this issue, you need to consider the device of a conventional model.
What an endoscope consists of
The endoscope (technical) includes a tube, a tube, as well as a loop. The lenses of the models are used in different diameters. Locks are usually installed behind adapters.
Most devices are made with a connector, which is a light source. The valve in the devices is designed for a certain pressure. The adjustment of the endoscope is carried out due to the lever.
Device types
By design, flexible and rigid devices are distinguished. Depending on the type of action, there are optical, lens, and gradient modifications. Devices can be produced with or without a repeater.
Description of flexible models
The technical endoscope (flexible, digital) is actively used to examine the condition of pipes. Valves for models are installed with heads. The limiting tilt angle of the described devices is at least 40 degrees. Levers are used to control the end.
The lenses on the technical (flexible) endoscope are installed directional type. Most modifications are assembled with air supply valves. It should also be noted that there are models with a train. As a rule, they use a long tube. There are modifications with and without lighting.
Hard Drive Features
A tough technical endoscope is made with steel tubes. The lens diameter of the models is at least 1.3 cm. It is also worth noting that the suction valves withstand a lot of pressure. The maximum angle of inclination is not more than 10 degrees. The levers in the devices are used with a connector. There is a special operating channel in the handset. The maximum pressure of the modifications is at least 4 Pa. Loops are used in different diameters.
The average length of the tube is 8 cm. Locks are used with and without levers. Many endoscopes have biopsy valves. Models of this type can be used to examine not only pipes, but also complex mechanisms. The maximum allowable temperature of endoscopes of this type is 40 degrees.
Optical Modifications
Optical models stand out for high resolution. There are many compact devices. They use adapters to supply air to the tube. Valves are typically used operating type.
The maximum pressure of the devices is 4 Pa. The focal length is at least 2.5 cm. The tubes for the modifications are used in a small size. Some devices are well suited for examining instruments. Air supply valves are used with covers. It should also be noted that the devices differ in viewing angle. The ends are usually made of polymer. Switches are used with and without clamps.
Lens endoscopes
A lens endoscope (technical) is suitable for working in a humid environment. The characteristics of this device depend on the manufacturer. The tubes of the models are used of small diameter, and the ends are installed in different shapes. Most endoscopes are made with one head. The levers in this case are installed on the remote control. The supply valves are designed for low pressure. Locks are used with and without filters.
Some endoscopes boast compact sizes. Controllers are installed behind the tubes. The viewing angle in devices reaches a maximum of 45 degrees. Surgical valves are found with linings and without them. The switches are of different types. Guided tubes are used with a diameter of 1.3 cm.
Some devices are made with moving heads. It should also be noted that the maximum allowable temperature for the use of endoscopes of this type is 30 degrees.
Gradient Device Options
Gradient borescope-endoscope (technical) is made for examination of large drive devices. These models allow you to inspect and tanks of different sizes. Some devices are made with duct tubes.
Most endoscopes can withstand pressure above 4 Pa. Devices with suction valves are compact. The lenses they use are small in diameter, and the limiting angle of rotation is approximately 40 degrees.
The minimum focal length reaches 1.5 cm. The levers are used with connectors. Quite often, moving tubes are installed on endoscopes. Loops are used from 7 cm long. Feed valves are used on 3 and 5 Pa. Connectors are used with and without a connector. It should also be noted that the tubes are used with controllers. Some modifications are made with two connectors.
Description of models with repeaters
Devices with a repeater are manufactured with an overview of 40 degrees. Their tube diameter is not more than 1 cm. The supply valves are usually designed for 4 Pa. Locks are used only with overlays.
Technical endoscope with repeaters is great for plumbers. Many modifications have short tubes. Heads are used with and without tips. If we consider models with operational amplifiers, then the lenses they use are small in diameter. The levers of the models are made with channel adapters. Universal loops are used in different lengths.
Tube devices
Tube modifications are actively used at large metallurgical enterprises. Most devices are made with contact type connectors. Some of them are made with one lock. The viewing angle averages 30 degrees. The minimum focal length is not more than 1.8 mm. If we consider devices with loops, then they are made with linear adapters. Most devices are made with long tubes.
It should also be noted that the modifications mentioned differ in size. If we consider models with controlled tubes, they have high resolution. Controllers are used with pads. Heads for devices are suitable for different shapes. The maximum allowable temperature when using such endoscopes is 45 degrees.
Models of jProbe ST
Devices of this brand are distinguished by high resolution. Modern models are made with movable tubes. It should also be noted that there are devices with contactors. Some of them work with a controlled head.
The controllers are small in size. Locks on the endoscope (technical), as a rule, are installed with filters. On average, the tube diameter is 1.4 cm. The feed valves for the versions are designed for 3 Pa. Loops are used with and without connectors.
Some models are made with connectors. As a rule, they are used for inspection of containers. It is also important to note that the protection systems for endoscopes of this brand are used in the P30 series.
If we consider devices with operating valves, they operate at high pressure. The angle of inclination is not more than 4 degrees. The optimal focal length is 5 cm. Repair of technical endoscopes is carried out only in specialized service centers.
Olympus Endoscopes
Models of this brand are distinguished by moving tubes. The heads on the endoscope (technical) are installed of small diameter. In this case, the linings are made of polyurethane. Most devices are made with adapters. Lenses are installed with overlays and without them. Aspiration valves for models are designed for a pressure of 4 Pa. Protection systems are used in the P30 and P40 series. Feed valves are used with connectors.
Some modifications work from controlled tubes. If we consider devices on biopsy valves, they are made with short tubes. Their viewing angle is a maximum of 30 degrees.
For a technical endoscope, the market price reaches 35 thousand rubles. The optimal focal length for examination is 4 cm. The locks for the modifications are installed only behind the adapter. The maximum allowable temperature for using endoscopes of the specified manufacturer is 40 degrees. Among the shortcomings can be noted only the high cost of goods.
Models Testo
Endoscopes from this company can be used to inspect furnaces. Their minimum focal length is 0.5 cm. Tubes are used with a diameter of 1.4 cm or more. Levers are usually mounted on convectors. Most of these devices are made with switches. Loops are used with flexible racks. Some endoscopes can work in high humidity. It should also be noted that there are modifications with operational valves. The maximum pressure in them is at least 2 Pa.
Protection systems are applied by the P33 series. The ends in this case are controlled by levers. Controllers are used with and without connectors. Connectors are installed only with overlays. The maximum permissible temperature for the use of endoscopes of the specified manufacturer is approximately 45 degrees.
