External Mount, Pressure to 1000 psig (69 bar), Temperature to 475°F (246°C), Minimum Specific Gravity 0.40
Low specific gravity and superior long term performance make this Series ideal for applications which require operation at specific gravities as low as 0.40. This Series also provides a heavy duty flanged chamber with removable stainless steel float for easy inspection and maintenance. Chamber is rated for operation of 1000 psig (69 bar) at 100°F (38°C), and 850 psig (59 bar) at 475°F (246°C). 1" NPT process connections are standard. Socket weld hubs or flanged connections are optional. Various circuits are available in SPST, SPDT or DPDT configurations with hermetically sealed snap action or mercury contacts. Enclosures are general purpose, weatherproof, explosion-proof, or explosion-proof – vapor proof.
