液压系统的压力是所有液压执行器的工作动力，也是大部分液压控制元件的控制动力，它存在与液压元件密封的容腔和链接液压元件的管路内，反映着液压系统的工作状态，是整个系统的重要信息。对着传感器向集成化、智能化、小型化、系列化和标准化方面的发展，加上它与现代测控技术、计算机技术和信号分析技术的日益接口，使得压力传感器在液压系统的运行控制、状态监测、故障诊断和科学试验中得到更为广泛的应用。

压力传感器是能感受压力信号，并能按照一定的规律将压力信号转换成可用的输出的电信号的器件或装置。通常由压力敏感元件和信号处理单元组成。按不同的测试压力类型，压力传感器可分为表压传感器、差压传感器和绝压传感器。

由于压力传感器具有全密封不锈钢焊接结构、小体积、高灵敏度、零点满度可调节应可用于液压、压铸、中央空调系统、恒压供水、机车制动系统轻工、机械、冶金、石化、环保、空压机等其他自动控制系统。并且在不同环境下，需要使用不同类型的压力传感器，那是因为在测量压力的过程中，压力传感器会随着工作环境和静压的变化而发生漂移，这在微差压测量过程中表现*为明显。压力传感器要有适应不同环境工作的能力，不能因为环境的变化而导致压力测量值发生漂移，这也是保障生产工艺连续性的关键。

压力传感器是气压或者液压压强力值的产品统称,在选型时细分为压力传感器和压力变送器两大类。压力传感器是一种接受压力变量,经数字电路转换后,将压力变化量按一定比例转换为标准输出信号的元件。 压力传感器输出的是一个毫伏电压信号,会根据激励电压的大小而改变输出值的大小,单位是mv;缺点是在实际使用时一般需要经过后部电路的放大处理才能使用,同时因为信号小易受到干扰,优点是精度高。压力变送器输出是一个经过放大处理后的模拟量信号(0-10V4-20mA),在15-36V的供电范围内输出信号不受影响。 优点是可以直接并入后部控制系统(PLC等)直接使用,抗干扰性强;缺点是相对于传感器的精度要低一个等级。

工作原理:
被测介质的两种压力通入高,低两压力室,低压室压力采用大气压或真空,作用在元(即敏感元件)的两侧隔离膜片上,通过隔离片和元件内的填充液传送到测量膜片两侧。压力变送器是由测量膜片与两侧绝缘片上的电极各组成一个电容器。当两侧压力不一致时,致使测量膜片产生位移,其位移量和压力差成正比,故两侧电容量就不等,通过振荡和解调环节,转换成与压力成正比的信号.

压力传感器是使用为广泛的一种传感器。传统的压力传感器以机械结构型的器件为主，以弹性元件的形变指示压力，但这种结构尺寸大、质量重，不能提供电学输出。随着半导体技术的发展，半导体压力传感器也应运而生。其特点是体积小、质量轻、准确度高、温度特性好。特别是随着MEMS技术的发展，半导体传感器向着微型化发展，而且其功耗小、可靠性高。

    传感器的接线一向是客户采购过程咨询得多的问题之一，很多客户都不知道传感器如何连线，其实各种传感器的接线方式基本都是一样的，压力传感器一般有两线制、三线制、四线制，有的还有五线制的。
　　压力传感器两线制比较简单，一般客户都知道怎么接线，一根线连接电源正极，另一个线也就是信号线经过仪器连接到电源负极，这种是简单的，压力传感器三线制是在两线制基础上加了一个线，这根线直接连接到电源的负极，较两线制麻烦一点。四线制压力传感器肯定是两个电源输入端，另外两个是信号输出端。四线制的多半是电压输出而不是4~20mA输出，4~20mA的叫压力变送器，多数做成两线制的。压力传感器的信号输出有些是没有经过放大的，满量程输出只有几十毫伏，而有些压力传感器在内部有放大电路，满量程输出为0~2V。至于怎么接到显示仪表，要看仪表的量程是多大，如果有和输出信号相适应的档位，就可以直接测量，否则要加信号调整电路。五线制压力传感器与四线制相差不大，市面上五线制的传感器也比较少。

1、压阻式力传感器
电阻应变片是压阻式应变传感器的主要组成部分之一。金属电阻应变片的工作原理是吸附在基体材料上应变电阻随机械形变而产生阻值变化的现象，俗称为电阻应变效应。
2、陶瓷压力传感器
陶瓷压力传感器基于压阻效应，压力直接作用在陶瓷膜片的前表面，使膜片产生微小的形变，厚膜电阻印刷在陶瓷膜片的背面，连接成一个惠斯通电桥，由于压敏电阻的压阻效应，使电桥产生一个与压力成正比的高度线性、与激励电压也成正比的电压信号，标准的信号根据压力量程的不同标定为2.0/3.0/3.3mV/V等，可以和应变式传感器相兼容。
3、扩散硅压力传感器：
扩散硅压力传感器工作原理也是基于压阻效应，利用压阻效应原理，被测介质的压力直接作用于传感器的膜片上(不锈钢或陶瓷)，使膜片产生与介质压力成正比的微位移，使传感器的电阻值发生变化，利用电子线路检测这一变化，并转换输出一个对应于这一压力的标准测量信号。
4、蓝宝石压力传感器：
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。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。
5、压电式压力传感器：
压电效应是压电传感器的主要工作原理，压电传感器不能用于静态测量，因为经过外力作用后的电荷，只有在回路具有无限大的输入阻抗时才得到保存。实际的情况不是这样的，所以这决定了压电传感器只能够测量动态的应力。
