MLC-80 APX - Explosion-Proof Level Switch

The MLC-80 APX level controller is the explosion-proof version of the MLC-80 line. It is supplied with an SPDT microswitch actuated by a magnetic field and mounted in an explosion-proof, weatherproof aluminum enclosure.

Applications

The MLC-80 APX is used for liquid level detection in marine tanks and process vessels where the electrical enclosure requirements call for the APX version.

Technical Characteristics

  • Side-mount or top-mount versions.
  • Available with different stem lengths on request.
  • Can be supplied coupled to an operation test valve when requested.
  • Standard flanged connection, 92 x 92.
  • ASME, DIN, and JIS configurations can be requested when applicable to the project.

Materials and Construction

The product is built with naval bronze, aluminum, and type 316 stainless steel components according to the cataloged configuration.
