LTC 隔膜(低温系数)是用于隔膜密封的不锈钢隔膜。由于其特殊的设计，它有两个稳定的位置，在这两个位置之间几乎可以无反应地偏转。因此，与其他不锈钢膜片相比，它可将每次压力测量中出现的温度误差降低多达 70%。

　　原文：

　　An LTC diaphragm (Low Temperature Coefficient) is a stainless steel diaphragm for diaphragm seals. Due to its special design, it has two stable positions between which it can be deflected almost reactionlessly. Thus it reduces the temperature error, which occurs in every pressure measurement, by up to 70 per cent compared to other stainless steel diaphragms.
