Chemically Resistant Level Transmitter

MPX-E Chemical

PVDF Float and Stem for use in Hostile Chemical Environments

With a chemical-resistant PVDF stem and float, the MPX-E Chemical delivers precision measurements in corrosive, acidic, and marine environments.  


The PVDF float and stem on the MPX-E Chemical are designed for use in corrosive, acidic, and marine environments. It can withstand sulfuric acid, boric acid, hydrochloric acid, and sodium hydroxide.

Modbus Output
The RS-485 Modbus RTU output makes the MPX compatible with any Modbus controller or PLC. It also simplifies wiring dramatically.

Tank Cloud Compatible
The MPX liquid level sensor is a Tank Cloud slave sensor, able to communicate via the Internet with the addition of an LOE Master sensor or an RST-5003 module.

Common Applications
  • C I, D 1 Hazardous Locations
  • Corrosive Chemicals
  • Marine (Salt Water) Environments
  • Sulfuric, Boric, or Hydrochloric Acids
  • Sodium Hydroxide
