DWYER 1211/1213/1214 flanged chamber level control

Low minimum specific gravity of 0.40 and rugged flanged chamber for inspection purposes helps insure superior long term performance. Control can be used at maximum process pressure of 450 psig (31 bar) at 100°F (38°C), and 300 psig (21 bar) at 500°F (260°C). Standard 1″ NPT connections are provided for mounting. 19 socket weld hubs or 1″ flanges are available as options. Hermetically sealed snap switch or mercury switches are provided in a variety of circuit configurations such as SPST, SPDT, or DPDT. High or low DC applications can also be accommodated. General purpose, weatherproof, explosion-proof, or explosion-proof – vapor proof enclosures are provided.
