O3EHa HENF315087R2 ABB 高压直流输电技术 DSP信号处理模块

O3EHa HENF315087R2属部件，压力敏感元件主要由压力敏感电桥、烧结管壳、填充陶瓷、金属膜片、焊环五部分组成，信号输出部分由引出信号输出线和PCB电路板组成。

表压压力传感器主要由压力敏感器件(芯体)、转换元件(信号处理电路)、压力接口及封装（机械结构及接插件)）3部分组成。压力敏感器件是传感器的核心功能元件，由硅基力敏敏感芯片、金属隔离膜片、保护液体，金属部件等组成。

转换元件（信号处理电路)包括补偿电路、放大电路、滤波电路等组成。硅基力敏敏感芯片把测量压力信号转换成电压信号(mV级)，再经过补偿和放大，使传感器输出调整到规定的标准规范信号0.5~ 5V。

O3EHa HENF315087R2 belongs to the component, the pressure sensitive element is mainly composed of pressure sensitive bridge, sintered tube shell, filled ceramic, metal diaphragm, welding ring five parts, the signal output part is composed of leading signal output line and PCB circuit board.

The gauge pressure sensor is mainly composed of three parts: pressure sensitive device (core), conversion element (signal processing circuit), pressure interface and package (mechanical structure and connector). The pressure sensitive device is the core functional component of the sensor, which is composed of silicon based force sensitive chip, metal isolation diaphragm, protective liquid, metal parts, etc.

The conversion element (signal processing circuit) consists of a compensation circuit, an amplifying circuit, a filtering circuit, etc. The silicon force sensitive chip converts the measured pressure signal into a voltage signal (mV level), and then compensates and amplifies, so that the sensor output is adjusted to the specified standard specification signal 0.5~ 5V.
