 一、用途Applications
      YXMS-100 型SF6 气体密度控制器/ 变送器主要应用于高压电器设备（如高压断路器、互感器、GIS 等）设备上，仪表通过输出开关信号，4～20mA 标准电流信号（或直接给出RS485标准接口）对高压电器设备内SF6气体的密度即可实现现场监测，又可实现远程控制。
      YXMS-100 SF6 density controllers / transmitters are mainly used in high voltage electrical equipment (such as high voltage breakers, mutual inductors, GIS etc.) The instrument outputs switch **, 4~20mA standard current **(or directly to RS485 standard ports) to remotely control SF6 gas density.
 
     二、工作原理Working Principle
      YXMS-100 型密度控制器/ 变送器是我公司开发生产的新型SF6气体密度测量控制产品，它采用了一种新型的机械电子相结合的设计方案，即将传统机械SF6 气体密度控制和电子技术融汇在一起。这一设计充分考虑了在使用现场的恶劣环境，如高低温、强电磁干扰及强震动冲击对仪表的影响，从而较大的提高了仪表的可靠性。仪表在设计上又考虑了在接入计算机测量系统时所必须的数字接口，以适应现代测量的需要。
      Integrating mechanical and electrical means ? a combination of conventional SF6 density controller and electrical technology, YXMS-100 density controller / transmitter is a new SF6 gas density measuring and control instrument developed by our company. This new design eliminates the concern about harsh working environment
like extreme temperature, high EMI and vibration, which may influence the instrument, therefore increases reliability greatly. Digital ports to computer measuring systems are provided to meet the requirement of modern measurement technology.
      该仪表在原理上采用了双重测量原理设计，首先将被测气体分为两路，一路送入波登管，另一路送入压力传感器。送入波登管的被测气体经过压力—密度转换补偿器件、传动器件推动指针在面板上直接显示压力值。另外，在被测气体达到和触及设定的报警值时，将直接驱动报警继电器的触点闭和，以便将该信号输出。这一设计的优点是利用机械式密度控制器传感器对温度、震动和电磁干扰的不敏感性和滞后性，有效的提高了在室外恶劣环境下的可靠性，尤其对**高压电力开关开启、闭合时所引起的强电磁脉冲干扰。经实验，这一设计对强电磁干扰情况下采用电子器件所引起的密度控制器驱动系统误动作，有很大的提高和改进。另一方面，为了适应数字测量系统的需要，另一路被测气体送入压力传感器。从传感器输出的被测压力信号经放大、模数转换、数字补偿处理、送入数字接口，以现代数字测量技术所具有的标准数字接口和工业控制信号输出，形成测量系统。
      This instrument features dual measuring elements. The measured gas is split into 2 paths, one to the bourdon tube, the other to the pressure transmitter. The gas pressure is shown on the dial thru the bourdon tube, pressure-density conversion compensator and mechanism, and it directly closes the contact of alarm relay when
the gas reaches the set point. The advantages of the mechanical element are insusceptibility and hysterisis to temperature, vibration and EMI especially when superhigh voltage switches act, and these efficiently improve performance in outdoor harsh environment. Practices have proved this design prevents system’s faulty function caused by EMI. On the other hand, to match digital measuring system, the pressure transmitter sends a ** out via magnifier， A/D convertor, digital compensator and standard digital ports of modern digital measurement technology, to build a measuring system.
    新型的SF6密度控制器/变送器充分考虑了现场的需求以及抗强电磁干扰的特性，另外使用电子技术、微控制器、通讯等先进技术，即保留了机械式压力控制器稳定可靠的特点，又使得新型仪表具备了不可比拟的优越性。
     The new SF6 density controller / transmitter takes care of onsite needs and high EMI, with electrical, micro-control, communication technologies, plus stable performance of the mechanical element, it gives the new instrument unmatchable advantage.
     YXMS-100 型密度控制器整机采用圆形结构，选用直径φ 100mm × 127mm 外壳，具有测控准确、抗干扰性能强等优点。整机体积小、功能齐全、工作可靠、使用方便灵活。
     YXMS-100 density controller is in round enclosure φ100mm x 127mm, features accurate measurement and control, compact size, multi-function, reliability and easy use.
    被测量的SF6气体，首先由定制筛选的进口高精度压力传感器测量出压力信号。这一信号经过内部精确温度补偿，克服了由环境温度产生的偏差。然后经补偿的传感器输出信号送入Ａ／Ｄ转换部分，Ａ／Ｄ转换电路对传感器的输出信号进行不小于0.1%的高精度模数转换。经过转换的数字压力测量信号，再次被送入下一级即微处理器部分。微处理器对被测量的信号分别进行更精细的温度、线性补偿，并进行压力密度的转换计算。转换后的密度数字信号较后送入输出部分，输出部分为模拟输出和数字输出两种，模拟输出部分采用了数模转换原理，输出４－２０m A标准工业信号。数字输出部分则直接给出ＲＳ４８５标准接口。

compensations, and pressure/density conversion. Finally the digital density ** goes to output unit, which consists of analog output and digital output. The analog output is standard industrial 4~20mA ** based on D/A conversion, the digital output is RS485 port.
