Level Instruments
RADAR (NON GUIDED) LEVEL TRANSMITTER
ELTAR-20
ELTAR-20 Through Air Radar Level Transmitter is a high-frequency 80 GHz pulse radar level instrument designed for accurate, non-contact continuous level measurement in liquids and solids. With a maximum measuring range of up to 30 meters, it delivers reliable performance even in reactors, silos, and complex process conditions. The transmitter features self-adjusting tracking radar technology and advanced microprocessor-based signal processing for stable and precise measurement. It offers 4–20 mA output with optional HART communication and supports two-wire or four-wire operation for flexible system integration. A rugged die-cast aluminium or stainless-steel enclosure with IP67 protection ensures durability in harsh industrial environments. ELTAR-20 is ideal for chemical, power, cement, water, and bulk material storage applications.
Configure the transmitter and electronics based on application, environment, and compliance requirements.
