Dwyer
Details: The Dwyer Mercoid 102 Flanged Chamber Type Level Controls are external cage type level switches, self-contained in a side mount body. Operating at pressure to 300 psig (20.7 bar) and temps to 425°F (218°C). Will operate to a min specific gravity of 0.60. Contains a stainless steel float. Well suited for applications where ease of accessibility is desired for pressure or vacuum vessels. Electrical circuits using hermetically sealed snap action contacts are available in a variety of actions including SPST, SPDT, DPDT and DPST combinations. Optional circuits are available for low current, low voltage direct circuits; high direct current or high temperature applications. Electrical enclosures provide general purpose; weatherproof, explosion-proof or explosion-proof/vapor proof capability. The 102 features three 1" NPT process connections for side/side or side/bottom piping. When using the side/side process connection, the bottom 1" NPT connection can be used as a drain.
