Pneumotach Transducer

The TSD107B highly linear, wide-range airflow transducer can be used to perform a variety of high-performance tests relating to airflow, lung volume, and expired gas analysis, and is ideal for applications that have large flow requirements (e.g., exercise physiology). The TSD107B consists of a high-performance pneumotach coupled with an internal, precision differential pressure transducer that converts the differential pressure generated across the pneumotach into a proportional voltage signal. The TSD107B interfaces with the DA100C general-purpose transducer amplifier.

The TSD107B is factory calibrated to nominally satisfy the scaling factor:

1 mVolt output = 11.1 liters/sec flow rate

When connected to the DA100C with Gain =1,000, the calibration factor is:

1 Volt = 11.1 liters/sec
