Powerful microprocessor controlled (fuzzy logic) stirrer for optimum performance and accuracy

A universal laboratory stirring motor for rheometric tests with powerful microprocessor control (fuzzy logic) for optimum performance and accuracy and a maximum torque of 150 Ncm, hollow shaft and precision chuck of 10.5 mm.

A multi-step safety system carries out a self test of all safety functions and detects and protects against overload as well as over temperature.

The bright back-lit digital display shows all relevant system data (power input, power output and torque) plus simultaneous display of set and actual motor speed. The display also allows for readout of the absolute or relative torque measurements as well as the power output in watts at the shaft.

Speed range 40-2000 rpm with soft start and soft stop logic.

Torque limits, maximum and minimum motor speeds are programmable.

The unit is supplied with an RS232-interface for computer control. There is also an analogue input for easy remote speed control and analogue output for recorder as well as a programmable switch-off timer.

The R100-series is designed for stirring jobs up to 200 litres (related to water); ideal for medium and high viscous media (1.000 -100.000 mPa·s).
