SOR compact level switches are machined from stainless steel and stands up to the harshest of process environments. They are designed to meet customers’ demands for highly efficient level switch products that require less space.

These switches utilize a float to operate the switching mechanism. 

Configuration choices are available for:

  1. Process connections - for flanged or NPT connections
  2. Float material - for different materials used for the float
  3. Switching mechanism - for different AC/DC ratings and temperature thresholds
  4. Accessories - For miscellaneous such as Certificates, Special Coatings, Additional Tests, Manual Check options

There are several types of Compact Level Switches available:

1510 Side Mounted Level Switch (Form CAT498)
1530 Side Mounted Pneumatic Level Switch (Form CAT500)
1540 Side Mounted Non-bleed Pneumatic Level Switch (Form CAT1337)
1550 Top Mounted Level Switch (Form CAT850)

1510 Side Mounted Level Switches

1510 Side Mounted Level Switch

1510 is a horizontally mounted, floatoperated level switch suitable for plant and OEM applications where open or closed contacts are required to signal presence or absence of liquid at a discrete level. The float extension arm moves a magnet which actuates (deactuates) a hermetically sealed reed switch. Actuation (deactuation) can be reversed by rotating the unit 180 degrees.

1530 Side Mounted Pneumatic Level Switches

1530 Side Mounted Pneumatic Level Switch

The 1530 is a horizontally mounted, float-operated level switch suitable for plant and OEM applications where pneumatic valve operation is required to signal presence or absence of liquid at a discrete level. The float extension arm moves a magnet which actuates (deactuates) a pilot valve to operate a pneumatic amplifier. Actuation (deactuation) can be reversed by rotating the unit 180 degrees

1540 Side Mounted Non-bleed Pneumatic Level Switches

1540 Side Mounted Non-bleed Pneumatic Level Switch

1540 is a horizontally mounted, floatoperated level switch suitable for plant and OEM applications where pneumatic valve operation is required to signal presence or absence of liquid at a discrete level. The float arm moves a magnet which in turn moves a shuttle that either blocks or allows pilot pressure to pass and operate ancillary equipment. Actuation (deactuation) can be reversed by rotating the unit 180 degrees or switching inlet connections.

The supply media must be filtered and oil free. Air is the usual media; however, any dry, filtered gas can be used.

1550 Top Mounted Level Switches

1550 Top Mounted Level Switch

The 1550 is a vertically mounted, float-operated level switch suitable for plant and OEM applications where open or closed contacts are required to signal presence or absence of liquid at a discrete level. The float stem moves a magnet that actuates (deactuates) a hermetically sealed reed switch.
