More Information:
Valmet Rotating Consistency Transmitter (Valmet Rotary) Is a rotating shear force consistency transmitter.
The sensor part consists of a shaft pair driven by an electric motor. The shafts are concentrically aligned
and flexibly connected together so that the inner (measuring) shaft is allowed to have a phase shift with
respect to the outer (drive) shaft.
A mixing propeller, mounted on the driveshaft, draws a continuous sample from the main process line past
the sensing element that is mounted on the measuring shaft. Shear force from the pulp suspension strives to retard the rotation of the measuring shaft and the sensing element, while the drive shaft is not subjected
to the shear force. Thus there will be a phase shift between the measuring shaft and the drive shaft.
Both shafts have separate cogwheels so that the phase shift can be measured by means of an optical
measurement system. The measured signal is converted in the transmitter electronics into a digital signal
and compensated for internal and external temperature variations, rotation variations and various compensations. The signal is then converted into a 4–20 mA output signal.

Device Support File Usage
FieldComm Group (FCG) makes available to its members and to the public certain device driver (DD) files, in various forms, that have passed certain tests conducted by or through FCG. The DD files are, or are created from, submissions to FCG by FCG members and are provided by FCG AS IS. FCG disclaims all liability for the accuracy, suitability or use of the DD files. Each member creating DD files has its own policies regarding supporting use of those files, and may, for instance support use of DD object code files, but not DeviceInfo or other files. While FCG is under no obligation to provide support for use of any DD files, FCG welcomes all inquiries on the subject and will often be able to assist.
