Page 5: Introduction
3. I NTRODUCTION The digital pressure gauge Type Q is a 0.15% precision class programmable digital gauge realised with a microcontroller, parameters programming can be done through the keyboard or through the RS232C (on request). Pressure sensor, manufactured on a strain gauge technology, ensures a long term stability. -
