The Endress+Hauser CM42-MAA000EAZ00 is a high-performance, ceramic capacitance level transmitter engineered for the most challenging bulk solid and liquid applications. Featuring an exceptionally rugged ceramic measuring probe, this sensor delivers reliable and continuous level measurement in environments with extreme temperatures, highly abrasive media, and demanding mechanical stress. It is the go-to solution for process engineers in cement, mining, metals, and power generation industries where standard sensors fail.
Core Features & Benefits (SEO Keywords: Ceramic Level Sensor, Abrasive Media Level Measurement, High Temperature Level Transmitter)
Ultra-Rugged Ceramic Probe: The heart of the CM42-MAA000EAZ00 is its wear-resistant ceramic sensor. It withstands extreme abrasion from materials like cement clinker, fly ash, ores, and aggregates, ensuring long service life and reduced maintenance costs.
Extended Temperature Range: Capable of operating in process temperatures up to 400 °C (752 °F), this transmitter is perfect for hot applications such as cyclone dust collectors, kiln feed bins, and hot air ducts.
Reliable in Sticky & Cohesive Media: The anti-adhesive properties of the smooth ceramic surface prevent buildup from paste-like or moist materials, guaranteeing stable measurement and minimizing process downtime.
Robust Process Connection & Housing: Designed with a sturdy flange process connection and a robust aluminum housing (protection class IP66/67, NEMA 4X), it is built for harsh industrial environments, including outdoor installations.
Simple Setup & Diagnostics: Features intuitive setup via local pushbuttons and clear, menu-driven display. Integrated diagnostics proactively alert users to potential issues like sensor coating or damage.
Global Safety & Quality Standards: Compliant with international standards such as IECEx, ATEX, FM, CSA for hazardous areas, and SIL2/3 according to IEC 61508, ensuring safety and regulatory compliance worldwide.
