Introduction
PRESSURE AMP.
NL108
The NL108A Pressure Amplifier module provides two gain settings, one appropriate for
blood pressure measurement (1.0V at the output corresponds to 100mmHg pressure at

Connections to Transducer
If a NeuroLog™ transducer is not being used an input plug type NL963K must be correctly wired to the particular
pressure transducer to be used with the NL108A.
The front panel socket, seen from the front of the NL108A panel, has the following connections :-
These connections are the same from the soldering end of the plug to be fitted to the transducer lead.
