Media Flow Controller TBM 901.2 and TBM 901.4


The 2013 newly developed TBM 901.x controller can control up to four nozzles simultaneously, and manage up to 4 different blasting media per nozzle. The dosage is designed for a wide flow range.

The calibration of the media takes place on site at the machine and can adjusted to a new medium at any time. For the backup of the calibration data, an USB interface is onboard.

The device meets the automotive and aerospace-standard SAE AMS2432c.

The following data were obtained in connection with a TBM-Roxor system consisting of:

  • a TBM 701.2 Fe-Flow-Meter,
  • a Roxor Dosing-Unit and
  • a Kollmorgen Servodrive with TBM Setup.
✓ Control accuracy typically <+/-3% of setpoint.
✓ Repeatability typically +/-1% of setpoint.
✓ Control range with Fe-Sensor “M”: 0,5 – 14 kg / min.
✓ Control range with Fe-Sensor “S”: 0,1 – 1,4 kg / min.

The Media Flow controllers works as a Closed Loop Controller. There are 2 versions available:

TBM 901.2

  • 2 Control Loops (Nozzles)
  • with each 4 linearizations (Media sizes/types)
  • with each up to 19 interpolation base points.

TBM 901.4

  • 4 Control Loops (Nozzles)
  • with each 4 linearizations (Media sizes/types)
  • with each up to 19 interpolation base points.

The controller is also suitable as a replacement for existing, obsolete flow controllers such as ASCON AC20 or Relamatik. This means that up to 4 pcs. Relamatik controllers or 2 pcs. Ascon AC20 can be replaced by one TBM 901.4 unit.
