Rosemount 644 Temperature Transmitter

Rosemount ™ 644 temperature transmitterRosemount 644 temperature transmitter functional diversity, can use HART ®, FOUNDATION or ™ fieldbus PROFIBUS ® agreement, with the top, field or track installation style as well as a variety of housing options. By adding a local operator interface (LOI), the transmitter configuration can be updated on the spot without tools. The transmitter also includes Hot Backup ™, warning and thermocouple sensor drift diagnostic functions such as performance degradation in response to different application requirements.Specifications*Precision+ / - 0.10 ° C (+ / - 0.18 ° F)*The stability of5-year stability*The quality assurance12/18 months, 3 years or 5 years limited warranty options*The inputUniversal sensor input (RTD, T/C, mV, ohms) is supported.
