Introduction - Valeport miniIPS2 Operating Manual

1 Introduction

The Valeport miniIPS2 and 2e "Intelligent Pressure Sensor" builds on the success of the industry standard
miniIPS.
•
The miniIPS2 operates over serial comms - RS232 and RS485.
•
The miniIPS2e operates over Ethernet (TCP/IP).
Designed to measure water pressure and provide a real time output of that data in a number of formats
and units. The miniIPS2 and 2e are fitted with an Interchangeable, depth optimised, pressure sensor
allowing the most operationally suitable pressure sensor module to be fitted for the operational water
depth. To be used in a variety of subsea applications ROVs, construction survey, monitoring and
positioning operations, 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 miniIPS2 and 2e offers several advantages over resonant quartz sensors,
with similar performance - cost, maintenance and operationally specific pressure ratings.
