High water meter is a body surface temperature and pressure you know?

Recently a lot of people are asking, what is high water meter? Why is also called a body surface temperature and pressure, to introduce to you today, we say at ordinary times the temperature and pressure of a surface is called water meter high, boiler instrumentation, etc. Mainly used in heating systems or other needs in the pipe system of measuring temperature and pressure at the same time. The dial pointer readings, can be clear at a glance whether equipment system in the correct temperature and pressure. Widely used in the heat pipe network, water supply, gas supply system. Temperature and pressure of a surface is thermal function of the bimetallic thermometer and the function of the pressure gauge pressure on a table. A table has the function of the two tables, but only occupy a space for installation. Temperature and pressure of a surface heat part is composed of double metal heat piece of shaft, etc. When the temperature changes, because the bimetallic strip of the materials of the two different linear expansion coefficient is relatively large, produce different expansion and contraction, leading to a bimetallic strip bending deformation, the amount of deformation of different produce different momentum, momentum transfer drive connection shaft, shaft drive at the other end of the indicating needle, indicating pointer is just on the correct reading, indicate the temperature. Pressure on the temperature and pressure surface parts is usually composed of elastic element and movement. Sensitive element within the pressure gauge by table bourdon tube elastic deformation, again by the transformation mechanism of movement in table will stress deformation to a pointer, pointer rotation to display the pressure. Process and equipment through the thread connection. Such as: installed in the pipeline pressure and temperature on the surface, according to different pipe, the connecting way of the body surface temperature and pressure also have different, mainly divided into two kinds of axial and radial. Below: type axial radial temperature and pressure usually a body surface temperature accuracy is: + / - 3 - 2 - Is 3%, the accuracy of pressure: + / - 1. 5%. Pressure and temperature of a body is a sheet multi-purpose instrument, when use should be strictly in accordance with the principle of custom and use.
