PNEUMOTACH AIRFLOW TRANSDUCERS
TSD137 SERIES FOR MP150/MP100 SYSTEM
SS46L-SS52L SERIES FOR MP3X AND MP45 SYSTEM
RX137 SERIES REPLACEMENT FLOW HEADS
The TSD137/
SS46L-SS52L series pneumotachs
can be used to perform a variety
of small animal
and human pulmonary measurements relating to
airflow, lung volume and expired gas analysis.
These pneumotach transducers consist of a low
flow, pneumotach airflow head (RX137B through
RX137H and SS46L through SS52L) coupled to a
precision, highly sensitive, differential pressure
transducer (TSD160A or SS40L).
The pneumotachs will connect directly to a
breathing circuit or plethysmogram chamber. For airflow and lung volume measurements, connect a short airflow
cannula to the RX137 series flow head. All pneumotachs are equipped with an internal heating element and
AC137A 6-volt power supply.

RX137 SERIES REPLACEMENT AIRFLOW HEADS (SHOWN ABOVE)
For TSD137 & SS46L-SS52L Series Pneumotachs
The RX137 series are airflow heads for the TSD137 a
nd SS46L-52L series pneumotach transducers. The RX137
heads can be mixed and matched with any of th
e TSD137 and SS46L-SS52L series pneumotachs. Switching one
head for another when using a single pneumotach can accommodate a wide range in flows. RX137 heads connect
to the TSD160A or SS40L differential pressure transducer via standard 3mm or 4mm ID tubing. Multiple RX137
heads help eliminate equipment downtime during cleaning procedures.
PNEUMOTACH AIRFLOW TRANSDUCER CALIBRATION
Connect tubing between the calibration syringe and the transducer, then follow the procedure for
TSD117/SS11LA but move the calibration syringe plunger at a reduced velocity due to the very high sensitivity to
flow of the TSD137/SS46L-SS52L series. Each of the TSD137/SS46L-SS52L series is factory calibrated to a
known flow level, as indicated on the transducer.
FLOW HEAD CLEANING & DISINFECTION
IMPOR
TANT:
RX137 series airflow heads are manufactured with a very thin layer of synthetic resin, so they should
never be cleaned with an organic solvent. We recommend cleaners such as Hydro-Merfen at the
concentration used for medical material, or Gluterex.
Before using the airflow head, be sure it is dry.
Never heat the airflow head higher than 50 C.
1. Submerge the airflow head in a disinfectant solution for approximately one hour.
2. Rinse the airflow head with distilled or de-mineralized water.
3. Use compressed air or another compressed gas [pressure up to 5kg / cm2 (5 bar)] to drive any
remaining water out of the airflow head.
4. Allow the airflow head to dry completely in ambient air (or continue using compressed air if time
requires it).
