Valeport Dual miniIPS

The Dual miniIPS is a development of the industry standard miniIPS precision underwater pressure sensor



2x 0.01% accuracy, independent pressure sensors are mounted in the front face of the instrument offering redundant observations and potentially, vessel time saving where multiple observation sessions can be carried out in a single sortie.

Titanium housing and a choice of pressure ranges make it a cost effective solution for offshore engineers, vehicle pilots, and other operators who require highly accurate and redundant depth information in real time.

Pressure Sensor
The pressure sensors fitted to the miniIPS are temperature compensated piezo-resistive sensors,
which deliver the performance previously only available from a resonant quartz sensor
at a more cost-effective price.
It also brings the added advantages of long-term stability, allowing longer intervals
between calibration, and a smaller and more robust construction;
complex and vulnerable arrangements of diaphragms and oil filled
capillaries & reservoirs are therefore no longer necessary.
