Technical endoscope: description, characteristics, device

The endoscope is a device for examining hard-to-reach places. Its technical modifications are actively used in industry. At metallurgical plants, devices of this type are used for inspection of furnaces. Also endoscopes give the opportunity to look inside different tanks.

The main parameters of the devices include resolution, focal length, tilt radius and viewing angle. To understand this question, we need to consider the device of the conventional model.

What the endoscope consists of

The endoscope (technical) includes a tube, a tube, and also a loop. The lenses of the models are of different diameters. Locks, as a rule, are installed behind the adapters.

Most devices are made with a connector that is a light source. The valve in the devices is designed for a certain pressure. Adjustment of the endoscope is carried out due to the lever.

Types of devices

By design, flexible and rigid devices are selected. Depending on the type of action, there are optical, lens, and gradient modifications. Devices can be issued with or without a repeater.

Description of flexible models

The technical endoscope (flexible, digital) is actively used to inspect the condition of pipes. Valves for models are installed with heads. The limiting angle of inclination for the described devices is not less than 40 degrees. To control the end, levers are used.

Lenses for the technical endoscope (flexible) are installed in a directional type. Most modifications are assembled with air supply valves. Also it should be noted that there are models with a loop. As a rule, they use a long tube. There are modifications with and without lighting.

Characteristics of hard drives

A rigid technical endoscope is made with steel tubes. The diameter of the lens in the models equals not less than 1.3 cm. It is also worth noting that aspiration valves withstand a great deal of pressure. The maximum angle of inclination is no more than 10 degrees. The levers in the devices are used with the connector. In the tube there is a special operating channel. The limiting 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 levers and without them. Many endoscopes have biopsy valves. Models of this type can be used to examine not only pipes, but also complex mechanisms. The maximum permissible temperature of endoscopes of this type is 40 degrees.

Optical modifications

Optical models are distinguished by high resolution. There are many compact devices. They use adapters to supply air to the tube. Valves are usually used in the operating type.

The limiting pressure of the devices is 4 Pa. The focal length is at least 2.5 cm. Tubes for modifications are of small size. Some devices are well suited for examining devices. The air supply valves are used with overlays. Also it should be noted that the devices differ in viewing angle. The ends are made, as a rule, from a 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 depends on the manufacturer. Tubes for models are of small diameter, and the ends are set in different shapes. Most endoscopes are made with one head. The levers in this case are installed on the console. Feed valves are designed for low pressure. Locks are used with filters and without them.

Some endoscopes are capable of boasting of compact dimensions. Controllers are installed behind the tubes. The viewing angle in the devices reaches a maximum of 45 degrees. Operating valves are found with and without linings. The switches are of different types. Controlled tubes are used with a diameter of 1.3 cm.

Some devices are made with movable heads. It should also be noted that the maximum permissible temperature for the use of endoscopes of this type is 30 degrees.

Parameters of gradient devices

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 channel tubes.

Most endoscopes can withstand pressures above 4 Pa. Devices with aspiration valves are distinguished by their compactness. The lenses they use are of small diameter, and the limiting angle of the rim is approximately 40 degrees.

The minimum focal length is 1.5 cm. Levers are used with connectors. Quite often, mobile tubes are installed on endoscopes. Loops are used for a length of 7 cm. The flow valves are used for 3 and 5 Pa. Connectors are used with the connector and without it. 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 produced with an overview of 40 degrees. The diameter of the tube at them is equal to no more than 1 cm. The flow valves, as a rule, are calculated for 4 Pa. Locks are used only with overlays.

The technical endoscope with repeaters is well suited for plumbers. Many modifications have short tubes. The heads are used with and without tips. If we consider models with operational amplifiers, the lenses they use are of small diameter. The levers of the models are made with channel adapters. Universal loops are used in different lengths.

Tube devices

Tubular modifications are actively used in large steel plants. Most devices are made with connectors of the contact type. Some of them are made with one lock. The average viewing angle is 30 degrees. The minimum focal length is not more than 1.8 mm. If we consider devices with loops, they are made with linear adapters. Most devices are manufactured with long tubes.

It should also be noted that these modifications differ in size. If we consider models with controlled tubes, then they have a high resolution. Controllers are used with pads. The heads for the devices are of different shapes. The maximum allowable temperature when using such endoscopes is 45 degrees.

JProbe ST models

Devices of this brand are distinguished by high resolution. Modern models are made with movable tubes. Also it should be noted that there are devices with contactors. Some of them work with a controlled head.

Controllers are of small size. Locks on the endoscope (technical), as a rule, are installed with filters. The average diameter of the tube is 1.4 cm. The flow valves for the modifications are designed for 3 Pa. Loops are used with connectors and without them.

Some models are made with connectors. As a rule, they are used for inspection of containers. It is also important to note that 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. Technical endoscopes are repaired only in specialized service centers.

Olympus endoscopes

Models of this brand are allocated mobile tubes. The heads for the endoscope (technical) are installed with a small diameter. In this case, the lining is made of polyurethane. Most devices are made with adapters. Lenses are installed with and without overlays. Aspiration valves for the models are designed for a pressure of 4 Pa. Protection systems are applied series P30 and P40. 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. The viewing angle at them is a maximum of 30 degrees.

On a technical endoscope, the market price reaches 35 thousand rubles. The optimal focal length for the survey is 4 cm. Locks for modifications are installed only behind the adapter. The maximum permissible temperature of use of endoscopes of the specified manufacturer is equal to 40 degrees. Among the shortcomings can be noted only the high cost of goods.

Models of the company Testo

The endoscopes of this company can be used for inspection of furnaces. The minimum focal length is 0.5 cm. Tubes are used with a diameter of 1.4 cm. Levers are usually installed on convectors. Most of these devices are made with switches. Loops are used with flexible racks. Some endoscopes are able to work at high humidity. Also it should be noted that there are modifications with operational valves. The limiting pressure at them is equal not less than 2 Pa.

Protection systems are applied series P33. 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 of application of endoscopes of the specified manufacturer is approximately 45 degrees.
