Dual miniIPS - Precision Underwater Pressure Sensor

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.

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.
• The Dual miniIPS can be re-calibrated by customers using a Class A deadweight tester.

• Type: Temperature compensated piezo-resistive
• Range: 10, 30, 50, 100, 300 or 600 Bar
• Accuracy: ±0.01% FS
• Resolution: 0.001% FS

Data Acquisition

• Sampling: Continuous or data on demand.
• Data Rate: 1, 2, 4 or 8Hz continuous
• Units: Secondary calibration function allows conversion of dBar pressure units into metres or feet
• Tare: Tare Function allows correction for atmospheric offset. Each sensor has its own correction.
