ROSEMOUNT变送器644系列介绍

Rosemount 644 温度变送器专为在温度点丢失可能造成严重后果的控制应用中使用而设计。这些高精度的 Rosemount 644 温度变送器提供多种安装样式、现场外壳和通信协议，以满足您苛刻的安装需求。

每台 Rosemount 644 温度变送器为两线制设计，提供 4-20 mA/HART 模拟输出或完全数字的 FOUNDATION fieldbus 输出。每台设备可配置为多种传感器输入：RTD（电阻温度检测器）、热电偶、毫伏或欧姆。的 Rosemount 644 温度变送器通过传递重要的温度诊断信息和 PlantWeb 警报来支持 PlantWeb®，以确保过程健康并实现经济的单传感器架构。

将特定 RTD 传感器的温度-电阻曲线输入到 Rosemount 644 温度变送器中，可实现变送器与传感器的匹配。这消除了传感器互换导致的误差，可将精度提高多达 75%。集成的 LCD 显示屏可为温度测量和诊断提供本地指示，便于即时且准确地验证过程状态。

Rosemount 644 温度变送器符合 NAMUR NE 21 建议，确保在恶劣电磁兼容（EMC）环境中实现最佳变送器性能。此外，Rosemount 644 HART 型变送器符合 NAMUR NE 43 和 NE 89 建议。

Rosemount 644 温度变送器提供良好的安装灵活性。DIN A 型头部安装变送器适用于多种外壳以便远程安装，并可与传感器做成一体或远程安装。紧凑的导轨安装样式非常适合拥挤控制室中用于 DIN 导轨安装的狭小空间。

The Rosemount 644 temperature transmitter is designed for use in control applications where the loss of the temperature points may be detrimental. These highly accurate Rosemount 644 temperature transmitters are available in a variety of mounting styles, field housings, and communication protocols to meet your demanding installation requirements.

Each Rosemount 644 temperature transmitter is a 2-wire design providing either a 4-20 mA/HART or a completely digital FOUNDATION fieldbus ouput. Each unit can be configured for a variety of sensor inputs: RTD, themocouple, millivolt, or ohm. The advanced Rosemount 644 temperature transmitter powers PlantWeb ® by communicating important temperature diagnostics and PlantWeb alerts to ensure process health and enable economical single-sensor architecture.

Entering the temperature-resistance profile specific to the RTD sensor into the Rosemount 644 temperature transmitter results in transmitter-sensor matching. This eliminates the sensor interchangeability error, which can improve accuracy by up to 75%. The integral LCD display provides local indication of temperature measurement and diagnostics for immediate and accurate verification or process conditions.

Meeting the NAMUR NE 21 recommendations, the Rosemount 644 temperature transmitter ensures top transmitter perｆormance in harsh EMC environments. In addition, the Rosemount 644 HART transmitter meets NAMUR NE 43 and NE 89 recommendations.

The Rosemount 644 temperature transmitter offers great mounting flexibility. The DIN A style head mount transmitters fits a variety of housings for remote transmitter mounting and can be integral or remote mounted to a sensor. The compact rail mount style is great for DIN rail mounting in the tight spaces of a crowded control room.
