More info

The model MLS-4EX series level switches are a simple and reliable way to sense fluid levels. Magnetic floats actuate a reed switch at each switching point. In the explosion proof housing are terminal blocks to provide simple field wiring. Switches can be ordered Normally Open, Normally Closed or DPDT.

The switch points are fixed on the probe for reliable and repeatable operation. The overall probe length is adjustable by way of a stainless steel compression fitting giving the user some flexibility in installation.

Because each unit is custom fabricated for your application, options include flanged process connections,low specific gravity floats, high pressure floats, stilling wells, other materials of construction, and signal conditioners or control panels.
