Overview
The Vega RA-222 2US (PN177660) is a VEGAPULS C 22 level transmitter manufactured by VEGA, a leader in precision level and pressure measurement instrumentation. This radar level transmitter employs non-contact 80 GHz radar technology to measure liquids and bulk solids in tanks, silos, and open containers without physical contact with the measured medium.
Key Features
- 80 GHz Radar Technology: Non-contact measurement ensures maintenance-free operation and immunity to deposits, foam, and condensation
- High Accuracy: ±2 mm measurement accuracy independent of medium properties and environmental conditions
- 4-20 mA Analog Output: Standard industrial signal for seamless integration with PLC and control systems
- Compact Design: Low overall height with G1 1/2 (1.5″) thread mounting for easy installation
- Bluetooth Interface: On-site configuration and commissioning via VEGA Tools smartphone app
- Wide Application Range: Suitable for water treatment, pumping stations, overflow basins, and bulk solid silos
