The 644H intelligent temperature transmitter is an extension of the Rosemount temperature instrument series,Can accept 2, 3, and 4 wire thermal resistors, thermocouples, and resistance and millivolt inputs. Each transmitter undergoes ambient temperature characterization at the factory to reduce measurement errors throughout the entire operating temperature range.
The 644H model can be installed in the connecting shell of the sensor to form an integrated temperature component, or installed in a junction box far away from the sensor; Alternatively, use optional installation components to install the 644H on the guide rail. 644R can be directly installed on walls or DIN rails
Customized modular platform can meet your different needs through a single model
There are two specifications for DIN head mount and rail mount
4-20mA/HART supports FOUNDATION fieldbus or Profibus PA protocol
Enhanced LCD display screen performance with local operation interface
Enhanced accuracy and stability
Single sensor input, capable of connecting to thermal resistors, thermocouples, millivolts, and ohms
According to Karen van der Waals ˙ Transmitter-sensor matching using Dursen constant
Multiple housing options available
