　　变送器是一种较为常见的仪表类设备，它不仅应用广泛，而且还分为很多种类型，比如电容式变送器、高压变送器等。通过本文Ameya360电子元器件采购网的介绍，您将了解到电容式变送器是什么、电容式变送器有哪些类型？

什么是电容式变送器 电容式变送器有哪些类型

　　一、什么是电容式变送器

　　电容式变送器是高精度智能仪表，采用技术成熟的电容传感器，具有长期稳定性好，可靠性高的特点。通过数字技术，对传感器的温度和非线性进行补偿，大大的提高了传感器的精度和量程比范围。

      仪表具有HART通讯接口，可通专门为之配备的组态调试系统在计算上进行测试、组态、标定，也可用专门为之配备的手操器(与ROSEMONT275兼容)在现场进行组态和校正。适用于各类液体、气体和蒸汽的压力、差压、绝压的测量。

　　二、电容式变送器有哪些类型

　　电容式变送器包括GP型(表压力)、DP型(差压)、DR型(微差压)、AP型(绝对压力)、HP型(高静压)、LT型(法兰式液位变送器)、DP/GP型(远传差压/压力变送器)等类型。电容式变送器与智能放大板组合，可构成智能型压力变送器，它可通过符合HART协议的手操器相互通讯，进行设定和监控。

      电容式变送器主要用于测量气体、液体和蒸汽的压力、差压、负压、高静压、液位和绝对压力等参数，然后将其转换成4～20mA.DC信号输出。一侧接受被测压力信号，另一侧则与大气压力贯通，因此可用于测量表压力或负压。

　　电容式变送器是一种精度很高的智能仪表，它安装了技术成熟的电容传感器。电容式变送器的性能很稳定，而且可靠性是非常高的。
