      The PIK-2 device is described for measuring instantaneous pressure values in the range between 0.49 and ~98 kPa for static and high velocity processes. A small differential inductive gage called DMI-11 is used as a trigger. An inductive impedance incorporated into the measuring bridge diagonal and varying due to the oscillations of a pressure to be measured changes the bridge circuit parameters. A varying electrical output from the bridge circuit is registered by a built-in mi 11ivoltmeter which indicates an absolute pressure value in static modes, or by an oscilloscope showing instantaneous pressure values. The main characteristics of the device are given.
