  • Maintain constant speed and torque throughout the speed range
  • X-Y recorder output for charting and calibration of speed and torque
Electronically monitor and record speed and torque. These mixer systems are ideal for polymer chemistry—gather data on viscosity profiles, shear rate and shear stress, starting torque for plastic materials, flocculation points, and more.
All mixers come with a power supply/controller that provides filtered DC power for the motor, changing the voltage as necessary. Maintain constant shaft speed and torque within ±1% of preset values under varying line voltage conditions. Obtain torque readings with a simple flip of a switch.
Totally enclosed DC motor is long-life, permanent magnet, ball-bearing type. Motor has oversized brushes and skewed armature to avoid cogging at low speeds. A fast-acting circuit breaker protects components even if the motor is stalled.
The recorder output is nonisolated from AC lines for both speed and torque (1 mV/rpm; 10 mV/in-oz for direct-drive mixers and 1 mV/in-oz for gear-drive mixers) and cannot be grounded. Order isolation transformer separately from “Accessories”. Hook up to an X-Y recorder (sold separately) to draw calibration curves for viscosity. Input impedance of recorder must be at least 100 kΩ. Order connecting cable 04406-50 separately.
Mixers with optional torque limit control, higher torque, and different speed ranges are available—call our Application Specialists for details.
Direct-drive mixers 04406-10 and -12 include:
* two 304 SS paddles assemblies (1-1/2" and 2-1/2" propellers on 8-3/4"L shafts)
* chuck (accepts up to 1/2" dia shafts)
* 8"L x 5/8" dia mounting rod
* heavy-duty clamp
* 5-ft cord with three-prong plug
Direct-drive mixers 04406-00, -02, -20, -22 and gear-drive mixers 04407-00, -02, -20, -22 include:

* chuck (accepts up to 1/2" dia shafts)
* 8"L x 5/8" dia mounting rod
* heavy-duty clamp
* 5-ft cord with three-prong plug

  • Q:

    How many decimal places on the torque reading does this mixer have? In what viscosity range the torque read out is most sensitive?

      A:

      Since this is a high torque, low rpm, geared system, the readout is in actual revolutions per minute, with no decimal value, with 250 as the maximum rpm. This unit is designed to handle a viscosity range of 50 to 200,000 centipoise easily.

  • Q:

    How the torque is measured? Is there any torque sensor or is it back calculated from power?

      A:

      The torque is measured from the load that is applied to the motor. It is a measure of the resistance against the motor and the power that needs to be applied to maintain the speed the mixer is set at. That is then converted to a torque reading.
