Series 102/1102 Flanged Chamber Type Level Control

Operating Pressures to 300 PSIG

The Series 102 & 1102 Flanged Chamber Type Level Controls are external cage type level switches which are self-contained in a side mount body. The sturdy 102 Series operates at pressure to 400 psi (28 bar) and temperatures to 425°F (218°C). The 102 Series will operate to a minimum specific gravity of 0.60. The 1102 Series will operate to a specific gravity of 0.40 under the same operating pressure and temperature. The 102 and 1102 Series contain a stainless steel float and offer a choice of cast iron, cast steel, or inexpensive cast 316 SS float chamber. These series are well suited for applications where ease of accessibility is desired for pressure or vacuum vessels. Electrical circuits using hermetically sealed snap action or mercury 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 design also 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.
