APG MPX-E Chemically Resistant Level Transmitter

General

APG MPX-E Chemically Resistant Level Transmitter provides highly accurate and repeatable level readings in a wide variety of liquid level measurement applications. The MPX-R’s large, buoyant, and robust float allows it to be used in harsh applications where fouling or buildup might otherwise be of concern. The MPX-E’s lighter weight design allows it to be used in applications where space is limited.

The MPX-E Chemical has a chemical resistant coating, allowing for use in corrosive, acidic, and marine environments. And the MPX-F’s flexible stainless steel stem allows for installation in tall tanks without needing a crane. Anti-corrosion coating for use in hostile chemical environments. With a chemical resistant coating and a Kynar® float, the MPX-E Chemical delivers precision measurements in corrosive, acidic and marine environments.

Durable

The coating on the MPX-E Chemical is 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.
