A removeable stainless steel float enclosed in a flanged carbon steel chamber is featured in the durable, field proven 1241 series. External side mount series includes 1″ NPT process connections as standard or 1″ flanges as options. Pressure and temperature limits are 1440 psi (99 bar) at 100°F (38°C) and 1275 psi (87.9 bar) at 475°F (246°C). Minimum specific gravity for all models is 0.60. The models shown can be ordered with a variety of electrical arrangements including SPST, SPDT, or DPDT circuits in hermetically sealed snap action or mercury contacts. Switches can be ordered open on level rise or fall. Single pole double throw electrically independent circuits are available as well as low current or high DC current applications. A full range of enclosures are offered including general purpose NEMA-1; weatherproof NEMA-4X; (explosion-proof) and (explosion-proof – vapor-proof) groups B, C, D, E, F, G, NEMA-7-9.
