Product DescriptionProduct DescriptionRosemount 644RAI5RK single hart temperature transmitterIn the complex and demanding landscape of industrial process control and monitoring, accurate temperature measurement is of paramount importance. The Rosemount 644RAI5RK Single HART Temperature Transmitter emerges as a reliable and high - performance solution, designed to meet the diverse needs of various industries. This transmitter is part of the renowned Rosemount 644 series, which is globally recognized for its advanced features, robust construction, and exceptional accuracy.Sensor CompatibilityMeasurement AccuracyMeasurement RangeOne of the key strengths of the Rosemount 644RAI5RK is its wide range of sensor compatibility. It can be paired with various types of temperature sensors, including Resistance Temperature Detectors, thermocouples, and millivolt sensors. This versatility allows it to be used in a multitude of applications, from measuring the temperature of industrial processes with high - temperature thermocouples to monitoring the temperature in precision - controlled environments using RTDs. For RTDs, it supports different types such as Pt100 and Pt500, with accurate compensation for lead wire resistance to ensure precise measurements. The transmitter is designed to provide highly accurate temperature measurements. It incorporates advanced signal - processing algorithms that minimize noise and interference, resulting in precise and stable readings. The accuracy of the measurement depends on the type of sensor used. For example, when paired with a high - quality Pt100 RTD, it can achieve an accuracy of ±0.1 °C over a wide temperature range. In the case of thermocouples, the accuracy can be within a few degrees Celsius, depending on the type and quality of the thermocouple. The Rosemount 644RAI5RK offers an extensive measurement range, making it suitable for a wide variety of applications. When using RTDs, it can typically measure temperatures from as low as - 200 °C to as high as 850 °C. For thermocouples, the measurement range can be even wider, depending on the type. For instance, type K thermocouples can measure temperatures from - 270 °C to 1372 °C. This broad range allows the transmitter to be used in applications ranging from cryogenic processes to high - temperature industrial furnaces.Key Features:Typical Applications:1.Universal sensor input - Supports all standard RTDs and thermocouples2.Advanced diagnostics - Sensor drift detection and process noise monitoring3.Dual-compartment housing - Separate electronics and terminal compartments4.Intuitive configuration - Via HART communicator or push buttons5.Robust construction - Suitable for harsh industrial environments6.Global approvals - Certified for hazardous area installations Process piping temperature monitoring Tank temperature measurement Heat exchanger control Steam system monitoring Critical process temperature pointsSpecificationModel Number644RAI5RKTypeSingle-Channel HART Temperature TransmitterInput TypesRTD (Pt100, Pt200, Pt500, Pt1000, Ni120, Cu10) & Thermocouples (J,K,T,E,R,S,B,N,C,L)Output Signal4-20 mA HART 7Power Supply12-42 VDC (loop-powered)Accuracy±0.1% of span (RTD)±0.5°C or ±0.1% of reading (T/C)Ambient Temperature-40°C to +85°C (-40°F to +185°F)Process Temperature-200°C to +850°C (-328°F to +1562°F)Hazardous Area CertsATEX, IECEx, FM, CSA (Class I Div 1/Zone 0)CommunicationHART 7DisplayOptional LCD with push-button configurationMountingDIN rail or head-mountedEnclosure RatingIP66 / NEMA 4XWetted Materials316L SST (standard)Response Time<1 second (typical)Long-Term Stability±0.1% of URL/yearCertificationsSIL 2 (IEC 61508), CE, RoHSCompany ProfileCompany AchievementsKeRui (Weifang) Automation Equipment Co.
