由于压力表的量程和表面直径比较杂乱,到目前为止,仍有相当一部分压力表,因缺相应规格的“兆帕”表盘而不能完成改制。我们在实践中摸索了在原压力表盘上进行改制的新方法,不仅克服了缺表盘的困难,而且成本低,速度快。其方法如下: 1.用塑料片自制或到文具店买“ 0”到“10”11 As the pressure gauge range and surface diameter more messy, so far, there are still a considerable part of the pressure gauge, due to lack of corresponding specifications of the “megapascals” dial and can not be completed restructuring. In practice, we explored a new method of restructuring on the original pressure gauge, which not only overcomes the difficulty of missing the dial, but also has the advantages of low cost and high speed. The method is as follows: 1. Use plastic sheets to buy or “0” to “10” from stationery shop
