The Jewell Instruments A802 DeepWater Submersible Tiltmeter is a precision voltage-output tiltmeter designed for underwater measurements and other applications under high pressure. The housing is machined from a solid piece of 316 stainless steel and incorporates a high-pressure neoprene connector (700 bars depth rating). Inside are a gravity referenced electrolytic tilt sensor and our low-noise electronics, delivering sensitivity, high dynamic range and long term stability under the most demanding conditions. DeepWater tiltmeters are excellent choices for monitoring dams, oil platforms, pipelines and underwater machinery. DeepWater tiltmeters are also available with 4-20 mA and digital outputs.
