What Is a Hand Level?

A spirit level is a common measuring tool for measuring small angles. In the machinery industry and instrument manufacturing, it is used to measure the inclination angle with respect to the horizontal position, the flatness and straightness of the guide rails of machine tools, and the horizontal and vertical positions of the equipment installation. According to the shape of the spirit level, it can be divided into: universal level, cylinder level, integrated level, mini level, camera level, frame level, ruler level; according to the fixing method of the level, it can be divided into: adjustable level and Non-adjustable spirit level.

The spirit level of the spirit level is

The inspection of the spirit level must be carried out in accordance with the corresponding standards. The temperature in the inspection room should be 20 ± 2 , and the inspection should be carried out under the condition of being sturdy without vibration and away from heat sources. Before inspection, all parts of the spirit level must be scrubbed clean, and then placed on the metal plate in the inspection room, the same temperature time should not be less than 3h.

1. The two V-shaped measuring surfaces of the spirit level are the benchmark of measurement accuracy, and can not contact or rub against the rough surface in the measurement. Care must be taken during placement to avoid damage to the spirit level and undesired measurement errors due to scratches on the measurement surface.

Level detection technology has important application value in industrial production. Technological process is an important indicator for measuring whether an enterprise has advanced nature, has market competitiveness, and can keep ahead of competitors. With the rapid development of China's spirit level market, the application and R & D of core production technologies related to it will become the focus of attention of enterprises in the industry. Understanding the research and development trends, process equipment, technology applications, and trends of domestic and international spirit level production core technologies is critical for companies to improve product technical specifications and market competitiveness.

By referring to a large number of patent documents, a systematic introduction to the technological progress of the spirit level has been provided. Through detailed investigation and the collection of authoritative technical data and related information, we have provided customers with the status quo of core technology application, technology research and development, process equipment support, and high-end technology Application and other information are very useful for enterprises to understand the production technology and development status of various level products. In many automatic control and engineering designs, it is often necessary to use a spirit level to measure the tilt angle of a plane and display the measurement results.

The commercial application prospects include the application fields of level products, downstream products, domestic and foreign production status, domestic potential manufacturers, foreign manufacturers and scale, domestic and foreign production trends, market conditions and forecasts, analysis of supply and demand conditions, and forecast of domestic demand manufacturers and Contacts and other aspects have detailedly discussed the market situation and development direction of spirit level products, which can be used as an important decision-making reference for the development trend of spirit level product deep processing technology. It has become an indispensable and important tool in the fields of bridge erection, railway laying, civil engineering, petroleum drilling, aviation and navigation, industrial automation, intelligent platforms, and mechanical processing.

At present, the most accurate spirit level in the world is a German Lippmann product. Its principle is different from other spirit levels. Its interior is based on the principle of a physical pendulum and a capacitive displacement sensor to give the tilt angle. Its resolution: Better than 1 nrad, which is 0.000000057 degrees (0.0002 arc seconds), so it is known as the world's most accurate level.
