电容物位计是过程检测中常用的物位计之一。它具有一系列的优点,如:1)传感器是一组电极,无机械可动部分,故结构简单,坚固牢靠,使用维护方便,寿命长。2) 精确度高、可达0.5级以上。3)检测端消耗的电能较小,采取一定的措施,可做到几个微焦耳的程度,从而可 Capacitance level meter is one of the commonly used level meters in process measurement. It has a series of advantages, such as: 1) The sensor is a set of electrodes, no mechanical moving parts, so the structure is simple, solid and reliable, easy to use and maintain, long life. 2) high accuracy, up to 0.5 or more. 3) Detection of the end of the electrical consumption of smaller, to take certain measures, you can do a few micro-Joule degree, which can
