    1、固体膨胀式温度计

    膨胀式温度计
    膨胀式温度计的测温是基于物体受热时产生膨胀的原理,可分为液体膨胀式和固体膨胀式两种。这里主要介绍固体膨胀式温度计中的一种介绍双金属温度计

    双金属温度计
    双金属温度计是把两种膨胀系数不同的金属薄片焊接在一起制成的,是一种固体膨胀温度计,结构简单、牢固。双金属温度计可将温度变化转换成机械量变化,不仅用于测量温度,而且还用于温度控制装置(尤其是开关的“通断”控制),使用范围相当广泛。

    1、热电偶温度计

    特点:

    优点:
    1.测量精度高。因热电偶直接与被测对象接触,不受中间介质的影响。
    2.测量范围广。常用的热电偶从-50~+1600℃均可连续测量,某些特殊热电偶最低可测到-271--+2800℃如金铁镍铬和钨-铼。
    3.构造简单,使用方便。热电偶通常是由两种不同的金属丝组成,而且不受大小和开头的限制,外有保护套管,用起来非常方便。
    4.输出信号线性好,方便实现工业生产过程自动化。

    缺点:
    微分热电势较小,因而灵敏度较低;价格较贵,机械强度低,不适宜在还原性气氛或有金属蒸汽的条件下使用。

    电容式压传感器.gif

    单电容式压力传感器
    华夏棋牌 它由圆形薄膜与固定电极构成。薄膜在压力的作用下变形,从而改变电容器的容量,其灵敏度大致与薄膜的面积和压力成正比而与薄膜的张力和薄膜到固定电极的距离成反比。另一种型式的固定电极取凹形球面状,膜片为周边固定的张紧平面,膜片可用塑料镀金属层的方法制成。这种型式适于测量低压,并有较高过载能力。还可以采用带活塞动极膜片制成测量高压的单电容式压力传感器。这种型式可减小膜片的直接受压面积,以便采用较薄的膜片提高灵敏度。它还与各种补偿和保护部以及放大电路整体封装在一起,以便提高抗干扰能力。这种传感器适于测量动态高压和对飞行器进行遥测。单电容式压力传感器还有传声器式(即话筒式)和听诊器式等型式。

    差动电容式压力传感器
    它的受压膜片电极位于两个固定电极之间,构成两个电容器。在压力的作用下一个电容器的容量增大而另一个则相应减小,测量结果由差动式电路输出。它的固定电极是在凹曲的玻璃表面上镀金属层而制成。过载时膜片受到凹面的保护而不致破裂。差动电容式压力传感器比单电容式的灵敏度高、线性度好,但加工较困难(特别是难以保证对称性),而且不能实现对被测气体或液体的隔离,因此不宜于工作在有腐蚀性或杂质的流体中。
