ViscoPakt ® -rheo<br />
The ViscoPakt-Rheo model series is equipped with<br />
precision-torque measuring. The zero torque, which<br />
depends on the rotational speed, is registered by an<br />
automatic calibration process <strong>and</strong> is used to correct<br />
the actual torque signal. This allows the on-line<br />
determination of the viscosity (via a calibration table)<br />
as well as of other rheological parameters.<br />

Interfaces<br />
Analogue:<br />
Required rotational speed 0 - 10 V, 0/4-20mA<br />
Actual rotational speed (= required value or 0) 0 - 10 V, 0/4-20mA<br />
Actual torque value 0 - 10 V, 0/4-20mA<br />
Changes to the rotational speed which are caused<br />
by load fluctuations are registered by a digital<br />
revolution counter <strong>and</strong> are electronically regulated.<br />
The rotational speed can be pre-set via an analogue<br />
input or the serial interface. The actual rotational<br />
speed <strong>and</strong> the torque are issued via the analogue<br />
outputs <strong>and</strong> the serial interface.<br />
RS232:<br />
Send: Required rotational speed<br />
Received: Required rotational speed, actual rotational speed, actual torque value<br />
