解决差压膜盒高压侧压力响应不足的方法

A Method to Solve the Problem of Weak Response to the Pressure on the High Pressure Side of a Differential Capsule

介绍了差压膜盒的工作原理。通过从消除中心膜片的初始偏移入手,提出了一种新的热处理方法,解决了差压膜盒高压侧压力响应不足的缺陷,提高了温度补偿合格率及效率。

The working principle of a differential capsule is introduced in this paper. A new heat treatment method is presented to eliminate the initial offset of a center diaphragm, which solves the problem of weak response to the pressure on the high pressure side of a differential capsule, and improves pass rate and efficiency of temperature compensation.
