2. Introduction

The Valeport miniIPS “Intelligent Pressure Sensor” is designed to measure water pressure and provide a real time
output of that data. Suitable for use in a variety of subsea applications (ROV’s, construction, monitoring,
positioning), one of the key development drivers was to provide a cost effective alternative to the use of resonant
quartz pressure sensors. Using the very latest technology in temperature compensated piezo-resistive transducers,
the miniIPS offers several advantages over resonant quartz sensors, with similar performance.

· No external diaphragms, oil reservoir or oil-filled tubes

· Easy to clean – no salt build up

· Titanium construction

· Pressure ranges from 10 to 600Bar (approx 100m to 6000m water)

· Long term calibration stability

· May be recalibrated by customers using standard Class A deadweight tester (requires optional adapter)

· RS232 or addressable RS485 data output

· Choice of calibrated data formats

· Choice of sampling modes
