Product DescriptionProduct DescriptionRosemount 644R Rail Temperature Transmitter :The Rosemount 644R Rail Sensor Temperature Transmitter is a high - performance device designed for accurate temperature measurement in various industrial applications. With its 4 - 20 mA output and compatibility with Pt100 sensors, it offers reliable and stable temperature monitoring. This transmitter is part of the well - known Rosemount 644 series, which is renowned for its versatility and high - quality performance.High PrecisionRail : Mount DesignReliable ConstructionThe 644R is engineered to provide excellent accuracy in temperature sensing. By using a Pt100 sensor, it can precisely measure temperature changes. The transmitter - sensor matching feature allows for an up to 75% improvement in system accuracy. This means that it can accurately detect even the slightest temperature variations, making it ideal for applications where precision is crucial, such as in pharmaceutical manufacturing, chemical processes, and food and beverage production.The rail - mount style of the 644R offers great installation flexibility. It can be easily mounted on DIN rails in control cabinets, making it suitable for use in crowded or space - constrained environments. This design simplifies the installation process, reduces the need for complex mounting brackets, and allows for quick and easy replacement if necessary. It is especially beneficial in industrial plants where multiple transmitters need to be installed in a compact and organized manner.Built with high - quality materials, the 644R is designed to withstand harsh industrial environments. It has excellent resistance to vibration, shock, and temperature fluctuations. The transmitter's housing provides protection against dust, moisture, and corrosive substances, ensuring long - term reliable operation. This durability makes it suitable for use in various industrial settings, including oil and gas refineries, power plants, and manufacturing facilities.Key Features:Typical Applications:DIN Rail Mount - Saves panel spaceUniversal Input - Supports all standard RTDs & thermocouplesHART Communication - Digital configuration & monitoringIntrinsic Safety - Approved for Zone 0/1 hazardous areasHigh Accuracy - ±0.1°C with Pt100 sensorsProcess piping temperature monitoringHVAC system controlTank temperature profilingEnergy management systemsSpecificationModel644R (Rail-Mount Version)TypeSmart Temperature TransmitterSensor InputPt100, Pt1000, Ni120, Cu10 (Configurable)PerformanceAccuracy±0.1°C (for Pt100)Temperature Range-200°C to +850°C (Depends on sensor)Stability±0.05% URL/yearElectricalOutput4-20mA + HART 7Power Supply12-45V DC (Loop-Powered)Load Limit≤600Ω @ 24VMechanicalMountingDIN Rail (35mm)EnclosurePolycarbonate (IP66/NEMA 4X)TerminalsScrew Clamp (0.2-2.5mm2)EnvironmentalAmbient Temp.-40°C to +85°CHumidity0-100% RHCertificationsSafetySIL 2 (IEC 61508)Company ProfileCompany AchievementsKeRui (Weifang) Automation Equipment Co.
