Model 802 Deep Water Submersible Tiltmeter Series
Highlights:
Compare
The Model 802 DeepWater Series is the fully submersible cousin of our Model 801 Tuff Tilt Series. Performance features are the same, but the DeepWater housing is machined from a solid piece of 316 stainless steel and incorporates a high-pressure neoprene connector. The pressure rating is 250 bars (2500 meters depth). Higher-pressure versions may be special ordered. Temperature rating is governed by the neoprene connector. Wider temperature range is available with other connector types. Units are available in a variety of configurations including single axis (uniaxial), or dual-axis (biaxial), analog, digital, or 4-20mA outputs.
