PTY-20 Internal Electronic Pressure Gauge

TY-20 Internal Electronic Pressure Gauge (IEPG) is mainly designed for chamber pressure measurement in medium and large caliber guns. Such instruments can be placed in the powder chamber or cartridge case to record the chamber pressure signal during the firing. Neither the drilling holes at the bottom of barrels to install a sensor nor leading out cables through the breech system is needed.

IEPG is a completely autonomous system which contains all essential elements such as an internationally approved piezoelectric transducer, onboard electronics, power supply (standard battery) in a rugged steel housing of small dimensions. It features independence in measuring, high accuracy, easy handling, reliability, safety and above all cost-effectiveness. Any guns in service (caliber 57mm or above) can be used for the measurement tasks. All it takes is to activate system, place the IEPG in the powder chamber or cartridge case, fire, read out data into portable computer via infrared interface and USB interface, process data in field or laboratory. The IEPG can be used for R&D, acceptance or routine testing and for testing old ammunition stocks in service.
