Depth/Pressure Sensor for 1000m (3300 ft) Depth with 3cm ...

The Bar100 pressure sensor is a high-pressure underwater pressure sensor that is sealed from the water and ready to install in a watertight enclosure on your ROV, AUV, or other project. This sensor can measure depths down to 1000 meters, so you can go deeper than ever before! The sensor is the Keller LD Series Sealed Gauge pressure/temperature sensor with I 2 C communication.

submerging a pressure sensor under water? | Electronics ...

· A minor leak in the pressure sensor or tube would let an initial charge of air leak out. In either case preventing leaks can be a problem and this doesn't settle the issue of whether or not the sensor can be exposed to clean water. I wouldn't abandon the bubbler concept. It adds some complexity but allows some simplicity in terms of sensors and minor leakage or dirt is less of a problem. They ...

Waterproof pressure sensors - Sensors - Arduino Forum

· Hi, I'd like to know if any of you can recommend a cheap pressure sensor that can go underwater. I'm doing a project where I need to determine the pressure in two compartments filled with water. I'm searching for sensors but none of them seem waterproof. For example, I thought about using a Capacitive pressure sensor, but I have no idea if I can put it underwater without damaging it.

Digiquartz Water-Balanced Pressure Sensors for AUV, ROV ...

Many Digiquartz® High-Pressure Sensors are used either in fixed installations on the ocean floor, or deployed in a fixed vertical orientation in deep-sea probes, profilers, and some underwater vehicles. An orientation sensitivity can be observed in the laboratory if the sensors are flipped in the vertical direction. Depending on the type and range of the pressure sensor, a substantial portion ...

Pressure sensor for depth control of underwater vehicle ...

· Hi, Can anyone suggest me a pressure sensor for depth control of AUV for a maximum of 4-meter depth? The type of pressure sensor will be gauge/absolute, ratiometric? Moreover, I have already purchased a pressure sensor (Honeywell PX2EF1XX050PAAAX) for the same depth but it is showing a constant value 0f V and is not changing when I blow high pressure in its tip.
