4、蓝宝石压力变送器原理与应用
利用应变电阻式工作原理，采用硅-蓝宝石作为半导体敏感元件，具有无与伦比的计量特性。
蓝宝石系由单晶体绝缘体元素组成，不会发生滞后、疲劳和蠕变现象；蓝宝石比硅要坚固，硬度更高，不怕形变；蓝宝石有着非常好的弹性和绝缘特性（1000OC以内），因此，利用硅-蓝宝石制造的半导体敏感元件，对温度变化不敏感，即使在高温条件下，也有着很好的工作特性；蓝宝石的抗辐射特性极强；另外，硅-蓝宝石半导体敏感元件，无p-n漂移，因此，从根本上简化了制造工艺，提高了重复性，确保了高成品率。
用硅-蓝宝石半导体敏感元件制造的压力传感器和变送器，可在zui恶劣的工作条件下正常工作，并且可靠性高、精度好、温度误差极小、性价比高。

3、直接测量不同管道、罐体液体的压力差值。
变送器在测量过程中，常常会出现一些故障，故障的及时判定分析和处理，对正在进行了生产来说是至关重要的。我们根据日常维护中的经验，总结归纳了一些判定分析方法和分析流程。
(冲洗环 压力变送器)

2．根据被测压力气程：一般情况下，按实际丈量压力为丈量范畴的80%选取。要考虑系统的大压力。一般来说，压力变送器器压力范畴大值应该到达系统大压力值的1．5倍。一些水压和过程控造，有压力尖峰或者持续的脉冲。那些尖峰可能会到达“大”压力的5倍以至10倍，可能形成变送器的损坏。持续的高压脉冲，接近或者超越变送器的大额定压力，会缩短变送器的实用寿命。但进步变送器额定压力会牺牲变送器的分辩率。能够正在系统中使用缓冲器来削弱尖峰，那会降低传感器的响应速度。压力变送器一般设想成能正在2亿个周期中接受大压力而不会降低机能。正在选择变送器时可正在系统机能取变送器寿命之间找到一个合中的处理计划。a，这个时候很多人都会认为直接用mat系列的气压校验仪就可以了，涉及到负压直接跳到正压，我们生产的设计部在多年的设计校验中一直存在这样一个理论，如果负压到正压的范围过大，就好比现在这样，那么使用高压力变送器的时候，必须选择少个模块，分为负压到，到正压这个模块，这样在校验的时候既可以保证负压.m
