Laminar Flow Transducer ±120 LPM

Request More Info
Laminar Flow 2 LPS
Part #: TSD157B-MRI, TSD157B-MRI-01

The TSD157B-MRI laminar flow transducer (±120 LPM) is suitable for precision ventilator bidirectional airflow measurements or resting airflow measures in fMRI. It consists of flow head RX157B + pressure transducer TSD160A + Tubing. Tubing presses over the barbs on the flow head and transducer and should be cut to fit for max separation, typically 10 m for MRI or 0.5 m for non-MRI.

  • For ventilator flow measurements, the flow noise of TSD157B-MRI greatly outperforms earlier offering of TSD127 + TSD117B over the typical ventilator flow range of ±100 LPM.
  • For MRI use, the TSD157B-MRI  can go inside the bore; the tubing from the RX157B flow head goes through the waveguide to the TSD160A+DA100C in the Control Room and should be cut to fit. The TSD157B-MRI can also interface with the AFT35-MRI valve: AFT35-MRI to AFT7 tubing to AFT11E to RX157B. (This same setup also works with RX127, instead of RX157B, with an additional coupler AFT11B.)

BIOPAC supplied linearization polynomials are available on request as a template.

Additional or replacement flow heads available as RX157B. Ask about options for 60 LPM or below or  240 LPM and below.

Order with choice of 1 m tubing for non-MRI use or 20 m tubing for MRI use.
