STF128-F1H-012F0 压力变送器的相关原理（供参考理解此类产品）

（一）电阻应变片式压力变送器原理 STF128-F1H-012F0

压力变送器感受压力的电器元件一般为电阻应变片，这是一种将被测件上的压力转换成为一种电信号的敏感器件。电阻应变片应用·多的是金属电阻应变片和半导体应变片两种。金属电阻应变片又有丝状应变片和金属箔状应变片两种。通常是将应变片通过特殊的黏合剂紧密地粘合在产生力学应变基体上，当基体受力发生应力变化时，电阻应变片也一起产生形变，使应变片的阻值发生改变，从而使加在电阻上的电压发生变化。

（二）压阻式压力变送器原理 STF128-F1H-012F0

以hh21882188压力变送器为例，其由压阻式传感器和信号转换模块组成，传感器的核心部件为单晶硅片，当单晶硅片受压时，本身的电阻率要发生变化，通过半导体平面工艺在硅片上扩散形成四个电阻，连接成电桥，在恒定的电流作用下，可输出与压力信号成正比的电压信号，信号转换模块将传感器的电压信号经过处理，转换成4-20mA标准信号。这种类型的压力变送器可以用来测量流体（液体、气体和蒸汽）的压力，液位等参数，并将被测量信号转换成4-20mA标准信号输出，该输出可作为指示、记录和调节器的输入信号，具有体积小，重量轻，精度高，价格低等优点，可带有现场指示电表，零点迁移，量程扩展等功能，可本安和隔爆，具备有工业用压力变送器所有功能。

STF128-F1H-012F0 Relevant principles of pressure transmitters (for reference to understand such products)

(1) Principle of resistance strain gauge pressure transmitter STF128-F1H-012F0

The electrical component of a pressure transmitter that senses pressure is generally a resistance strain gauge, which is a sensitive device that converts the pressure on the device under test into an electrical signal. The most commonly used resistance strain gauges are metal resistance strain gauges and semiconductor strain gauges. There are two types of metal resistance strain gauges: wire strain gauges and metal foil strain gauges. Usually, the strain gauge is tightly bonded to the base body that generates mechanical strain through a special adhesive. When the base body is stressed and the stress changes, the resistance strain gauge also deforms, causing the resistance value of the strain gauge to change, thereby causing the stress to change. The voltage across the resistor changes.

(2) Principle of piezoresistive pressure transmitter STF128-F1H-012F0

Take the hh21882188 pressure transmitter as an example. It consists of a piezoresistive sensor and a signal conversion module. The core component of the sensor is a monocrystalline silicon wafer. When the monocrystalline silicon wafer is under pressure, its resistivity changes. Through the semiconductor The planar process diffuses four resistors on the silicon wafer and connects them to form a bridge. Under the action of a constant current, a voltage signal proportional to the pressure signal can be output. The signal conversion module processes the voltage signal of the sensor and converts it into 4- 20mA standard signal. This type of pressure transmitter can be used to measure the pressure, liquid level and other parameters of fluids (liquids, gases and steam), and convert the measured signal into a 4-20mA standard signal output, which can be used for indication, recording and The input signal of the regulator has the advantages of small size, light weight, high precision and low price. It can be equipped with functions such as on-site indicating meter, zero point migration, range expansion, etc. It can be intrinsically safe and explosion-proof, and has industrial pressure transmission. all functions of the device.
