Orifice meter scale resistance is commonly used materials and its main performance

Abstract: the orifice meter scale resistance is commonly used materials and its main performance information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Resistance materials commonly used at present and its main performance orifice flowmeter electrician instruments widely used in the resistance of the material with copper and manganese alloy and ni-cr alloy. Copper alloy with manganese copper ( Including silicon manganese copper and germanium manganese copper) 。 Lala, etc. Nickel-chromium alloy carma ( Nickel. More flow meter manufacturers choose model price quote you are welcome to inquire, below is the orifice meter scale resistance is commonly used materials and its main performance article details. Resistance materials commonly used at present and its main performance orifice flowmeter electrician instruments widely used in the resistance of the material with copper and manganese alloy and ni-cr alloy. Copper alloy with manganese copper ( Including silicon manganese copper and germanium manganese copper) 。 Lala, etc. Nickel-chromium alloy carma ( Nickel chrome aluminum and iron) And even (nickel chrome aluminum and copper) 。 Because the performance of these resistance material is different, so in manufacturing should be according to the specific requirements of resistance and resistance to choose them. Main parameters of common resistance materials have the following: 1, the resistivity of copper and manganese alloy resistivity is about 0. 4 ^ - 0. 5 x10 - 6 o & middot; Meters, the resistivity of chromium and nickel base alloy in 1. 31. 5 x10 - 6 o & middot; M, which is about three times the former. Generally speaking, high resistance rate higher the resistance of the material is suitable for manufacturing resistances. Low resistivity and the resistance of the material is suitable for making low resistance values. Sometimes in order to improve the resistance of the cooling conditions, need to increase the surface area, can choose high resistivity lower the resistance of the material to produce the resistances. Resistance of material after, still should according to different specifications of the resistance to select different wire diameter and different thickness. In order to facilitate calculation, resistance materials factory usually provide wire table to the user. This wire table lists the wire line diameter specifications, and corresponding resistance per meter length and a kilogram of wire length. 2, resistance temperature coefficient of resistance of the resistance value is changing with the temperature, the orifice meter the function relation is referred to as the temperature coefficient of resistance. Most of the multiple resistance alloy figure 5 - temperature coefficient of resistance can be used - The curve of the 13. In 0 ~ 70 ℃ temperature area, the temperature coefficient of resistance of copper and manganese base alloy basically similar to a parabola ( Figure 5 the curve of the 13 1) The peak point of the parabola between 20 ~ 50 ℃ temperature. The relationship between the resistance value and temperature can be accurately express: use the type 3, the time stability of the resistance of the materials used for the precise resistance stability should have a good time, namely its resistance value shall not have larger changes over time. The time stability of resistance materials are feeling close resistance stability is a prerequisite of time. 4. Thermoelectric potential of copper in orifice meter because in the manufacture and use of precise resistance, resistance material is always with other parts ( Such as lead, terminal, etc. ) Connection, and the vast majority of these parts is made of copper. Between different materials in order to avoid the thermoelectric potential caused by the temperature gradient, so the orifice meter, used in the manufacture of precision resistance mainly use under dc resistance) The resistance of the material for copper thermoelectric potential cannot too big,. Manganese, copper, kumar and even at room temperature for copper in thermoelectric power can do less than 1 microvolt / ℃, while the constantan up to more than 40 microvolt / ℃. Resistance material resistivity, temperature coefficient of resistance, time stability and thermoelectric potential of copper is directly related to material composition and its content. Precise resistance with the resistance of the material should be balanced with the main performance. Table 5 a 9 for manganese bronze, constantan, kumar and even resistance materials such as the main performance of CRT. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
