Specification:
Features:
Applications
• Level measurement of all liquids and solids.
• Distance measurement and object monitoring.
• Measurement through the wall of plastic vessels.
• Measurement in a vacuum.
• All slightly conductive substances and all substances with
a dielectric constant Sigma r > 1.5 can be measured.
• Meas. distances 0 … 20 m (standard), 0 … 30 m (optional).
Output signals
• Analogue - 4 … 20 mA or 0 … 20 mA.
• Digital - Profibus PA.
• Power supply and output signal on one two-wire cable (loop
powered).
