- Page 6 AN IMPROVED TECHNIQUE FOR UTILIZATION OF CONFORMAL BALLISTICS SENSOR CALIBRATION DATA The PCB Series 117B Conformal Ballistics Sensor (patented) measures chamber pressure in a novel manner. The sensitive surface of the sensor, when properly installed in the gun chamber, conforms or blends in precisely with the inside surface of the chamber actually forming a portion of the wall adjacent to the cartridge case.

Note that in this case, the sensitivity is identical to the slope of the line, since the line does intersect the origin by previous definition.
- Page 8 AN IMPROVED TECHNIQUE FOR UTILIZATION OF CONFORMAL BALLISTICS SENSOR CALIBRATION DATA At the lower pressures, the sensor has very little output (Eq. 4) because there is a certain amount of clearance between the cartridge case and the chamber wall. Obturation of the cartridge occurs in this region.

OPERATION MANUAL FOR CONFORMAL BALLISTICS PRESSURE SENSOR Series 117B LOW-END NONLINEARITY It will be noticed during calibration, especially with metallic cartridges, that a certain amount of pressure is necessary before linear output is attained from the conformal sensor. This is due to the fact that since the cartridge cases are made nominally smaller in diameter than the chamber to allow easy insertion and extraction, the case must be expanded slightly by the internal... - Page 16 OPERATION MANUAL FOR CONFORMAL BALLISTICS PRESSURE SENSOR Series 117B Drawing Number: 21086 Revision: NR...
