Information About 644HANAQ4
The 644HANAQ4 is a Rosemount 644 Series smart temperature transmitter configured for DIN A head mounting and single-sensor measurement. It accepts user-selectable temperature sensor inputs and provides a two-wire 4–20 mA output with HART digital communication for integration into industrial process control systems. The head-mount construction allows installation in compatible connection or universal heads, with optional hardware supporting DIN-rail mounting applications. The Q4 option specifies three-point calibration at 0%, 50%, and 100% of the configured range with a calibration certificate.
Key Features:
- DIN A Head Mount: Compact configuration designed for installation in compatible temperature sensor connection heads.
- Single Sensor Input: H configuration provides one user-selectable temperature sensor input.
- 4–20 mA Output: Produces a standard analog current signal for industrial monitoring and control equipment.
- HART Communication: Superimposes digital HART communication on the 4–20 mA signal for configuration and diagnostics.
- Two-Wire Operation: Uses a two-wire transmitter architecture for power and process signal transmission.
- Q4 Calibration Option: Includes three-point calibration at 0%, 50%, and 100% with a calibration certificate.
- Input/Output Isolation: Transmitter circuitry provides electrical isolation between sensor input and process output.
- Fast Measurement Update: Provides an update time of 0.5 second or less for temperature measurement response.
The 644HANAQ4 delivers the reliability and precision required for industrial temperature measurement, process monitoring, and control-system integration.
