A802 Datasheet C802 Datasheet D802 Datasheet

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.
