    0760824b - miniIPS Operating Manual 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.

  • Page 10: Pressure Tare

    0760824b - miniIPS Operating Manual 5.2.4. Pressure Tare The pressure sensor fitted to the miniIPS measures absolute pressure, i.e. it includes atmospheric pressure. The pressure tare function allows the atmospheric pressure (as measured by the sensor before deployment) to be removed from the readings, so the output is simply pressure of water.

  • Page 11: Data Output Formats

    The default output units for the miniIPS are deciBar (dBar), equivalent to 0.1Bar, or approximately 1m of seawater. The miniIPS can also output pressure in PSI. It is also possible to present the data in units of metres or feet of seawater, calculated using the UNESCO Simple Pressure / Depth relationship, which assumes “standard”...
