This pressure amplifier module is designed both for blood pressure measurements and for low pressure measurements such as intratracheal pressure.
The NL108A Pressure Amplifier module provides two gain settings, one appropriate for blood pressure measurement and the other for low pressure measurement such as intratracheal pressure. An internal voltage calibrate signal provides the appropriate deflection (1.0 V or 100 mV) for these two ranges. Other features include excellent DC stability, a push button switch for setting the zero pressure baseline on the recording instrument, and a sensitive zero offset control. Although the NL108A is designed to mate perfectly with our own pressure transducer, due to its internally adjustable gain and bridge excitation voltage, it can be used with a variety of other standard pressure transducers.
