The BDS series of stirrers are suitable for stirring and mixing liquids with both, low or high viscosity. They are designed for laboratory use with a sturdy construction and full-time utilization on mind.



The speed is regulated by a microprocessor based control system using a highly stable closed loop. The target or reference speed value is constantly compared with the actual speed value of the output shaft and pulse width modulation (PWM) action is performed in order to drive the motor and correct any variations. This guarantees a constant speed even if the viscosity of the substance being stirred changes. Fluctuations in the mains voltage within the permitted tolerance range have no effect on the quality of regulation and constancy of speed.

     
  Characteristics:
     
 
Microprocessor velocity control, maintains constant rotational speed regardless of viscosity changes as mixing progresses - ideal for pseudo plastic or thixotropic fluids. Speed regulation better than ±0.6%.

High torque, rugged, permanent-magnet, ball-bearing DC motor, direct drive motor able to handle viscous fluids up to 150000cp.

Three kind of action: single direction, reversible, continuous agitation.

Continuous agitation: provides instant, automatic forward and reverse rotation for thorough mixing without rotating vortexing. The resulting highly efficient action keeps material in homogeneous suspension and minimizing the formation of air bubbles. Variable reversing time cycle allows you to set the cycle time from 2 to 20 seconds. You can also use this unit as a regular mixer by turning off the reversing action.

Step less speed setting in RPMs, digital display presents target/actual speed.

Speed and torque readings.

Metal construction minimizes electromagnetic interference with other lab equipment.

Forced ventilation assures 100% permissible ON time.

Although not recommended for fuming corrosive materials it's sturdy construction make it ideal for harsh laboratory environments.

Special modification of the initial speed profile eliminates start-up overshooting.



Currently the BDS series of mixing devices have the following optional modules available:



Analog output.

Torque control.

RS-232 interface.

Data acquisition.

USB interface (Soon to be release).
