Product Description 644H and 644R intelligent temperature transmittersThe 644 provides a flexible and reliable solution suitable for any temperature measurement. 644 is a high-precision transmitter.It supports Hart, FOUNDATION fieldbus, or PROFIBUS PA communication protocolsand offers two installation forms: head mounted andrail mounted. It is specifically designed to meet your most demanding applications. The LCD display can display local measurementreadings and has a transmitter sensor matching function,which can achieve unparalleled accuracy in transmitter and RTDmeasurements. The 644H and 644R intelligent temperature transmitters are extensions of the Rosemount instrument series and canaccept 2, 3, and 4 wire thermistors, thermocouples, resistors, and millivolt inputs. Each transmitter undergoes ambienttemperature characterization atthefactory to reduce measurement errors throughout the entire operating temperature range.Features:* Extremely versatile temperature transmitter available in HART?, FOUNDATION? Fieldbus or PROFIBUS? protocols* Diverse mounting configurations including head, field or rail mount with many enclosure options* LOI option eliminates the need for special configuration tools (i.e. field communicator) for ease-of-use* Transmitter-sensor matching with Callendar-Van Dusen constants reduces total measurement error* Hot Backup? capability and sensor drift alert with dual sensors ensure measurement integrity* Thermocouple degradation diagnostic monitors thermocouple health to detect degradation before failure* Minimum and maximum temperature tracking observes temperature extremes for easy troubleshooting* Device dashboards provide easy interface for simplified device configuration and diagnostic troubleshooting Q:How long will you reply me?A:We will contact you as soon as possible but within 12 hoursQ: Can I get some samples?A: Yes, Sample order is available for quality check and market test.
