DIGIMATIC DML4AI Capacitance Level Control EN 60079/IEC 60079 (Dust Zone 20)
The Digimatic DML4AI sensor is a fixed point capacitive level control suitable for detecting liquids, powders & granular solids. Approved to ATEX EN 60079 & IECEx IEC 60079 standards for Explosive Dust Hazard Area use.
Automatic high/low level calibration with full manual override. LED display shows calibration & run mode readings.
110/230 Vac/24 Vdc supply connections in same unit. Volt free, change over relay output. Power shield compensator, prevents false signalling due to material build-up on probe rod. Adjustable timer to prevent false signalling from ‘splashing’ materials. Available with long or short power shield or flush probe mounting options. Simple calibration (Various length probe available). Mounting flange available as an option.
