MTL安全栅的技术说明

MTL安全栅的技术说明MTL是世界著名本安仪表品牌，本安技术多年居领先地位，MTL仪器仪表（中国）有限公司（以下简称MTL）是MTL公司全球业务的一部分，多年来在中国所有的大型石化企业的装置大量应用，占主装置进口安全栅份额的70％以上。

尤其在近几年百万吨乙烯和千万吨炼油项目中90％均采用MTL安全栅，如兰州乙烯，茂名乙烯，赛科100万吨乙烯，福建100万吨乙烯一体化（含1000万吨炼油），海南1000万吨大炼油，青岛1000万吨大炼油，燕山石化1000万吨炼油改造，广石化800万吨炼油，武石化800万吨炼油。

在这些大项目中，均采用DCS与安全栅整体采购，这样可以减少工作界面与中间环节，便于项目管理，提高工程效率，这种模式也是国际上正在流行的采购模式，说明中国的工程建设当正在引入先进的国际化工程理念。

在本项目中MTL可以提供成熟的、有丰富应用经验的底板安装方案，这是一种世界上最先进的接线和安装方式，优点在于：1．减少接线环节，减少故障点，提高系统可靠性。

2．节省机柜空间，减少机柜数量，利于控制室排布。

3．集成非常快捷，缩短开车调试周期。

4．便于系统运转后的日常维护和管理。

5．底板安装支持各家DCS厂商：Yokogawa, Honeywell, ABB, Foxboro, Triconex, Siemens，August Systems 。

6．已经取得IEC的SIL2认证，技术上亦可实现SIL3的安全标准。

为了更好地为中国的用户服务，MTL在上海和北京都配有丰富工程经验的高级应用工程师。

MTL引以自豪的是我们的生产效率和产品质量，但我们清醒地认识到在高速发展的工业领域，我们必须不断改进产品结构和提高质量，使MTL永远站在本质安全领域的前列,才能更好地服务用户。

P+F安全栅在国内使用故障的装置：1.2004年上海氯碱厂离子膜烧碱装置中P+F的温度变送器隔离栅使用时多次出现故障，更换过两次，给生产造成很大的影响。

MTL安全栅

主要特点
13.符合FSM认证标准（MTL FSM), MTL是过程仪表设备供应商中第一家取得该认证的厂家。对于安全完整性等级(SIL)认证是对整个回路的考虑而不只是某个部件，而对于具体的部件，不同的计算方式得出的SIL等级也不同，通常需要提供基本数据而不是SIL等级给ESD厂家计算整个回路的等级。（SIL)
主要特点
17. 安全栅和底板密集设计，减轻了重量，提高了安装密度。安全栅厚度仅16mm，底板有4、8、16、24个组件等多种选择。
客户化解决方案
主要特点
安全栅底板通过多芯插头及电缆直接与部分DCS I/O卡件连接，省去DCS 端子板及传统的由安全栅到端子板的点与点连接线，从而节省了机柜空间，简化了工程量，减少了人为错误，降低了工程费用。

MTL5500系列安全栅说明书

Key features of the MTL5500 Series are ease of application, high operational integrity and reliability, and low installed cost. Full 3-port isolation between the input, output and power supply circuits eliminates the need to think about relationships to earth, makes system hook-ups easier to arrange, and allows hazardous-area circuits to be left floating or earthed at any one point.
Where space is at a premium, high packing densities are essential. With a unit width of 16mm, and with many units providing multiple channels (and hence a lower cost per channel), the MTL5500 Series takes up a minimum of space – which leaves more for other process control equipment. Where older installations are being updated, there may be a need for more channels – but within the existing space. The MTL5500 Series can provide the answer, fitting extra units and channels into a space formerly occupied by bulkier isolators.
