About the A820 Shallow Water Submersible Tiltmeter

The A820 Shallow Water Tiltmeter is a high-precision submersible tiltmeter for use in fresh and salt waterapplications. Using an absolute gravity referenced electrolytic sensor, the A820 delivers superior measurement accuracywith virtually nolong-term drift.

High-gain units are sensitive to <0.0017mm/m or better. Output is a stable ±5 DC voltage, which can be read with any VDC input datarecorder. All units are rated to 200 meters(656.2 ft)waterproof for advanced protectionfrom the elements.

Use the A820“Shallow Water” for structural monitoring, angle measurement and control, platform leveling and more.

Configurations

Output options include analog (±5 VDC, ±10 VDC), current (4-20mA) and digital (RS232 and RS422).
