Measuring range0.05-30 m
Accuracy± 2 mm
Beam angle4°
Overview
The 80 GHz carrier gives a 4° beam, so the transmitter can be mounted on a narrow nozzle without seeing tank internals. A PTFE lens keeps product off the antenna, and the echo algorithm ignores foam and agitator blades that defeat 26 GHz instruments.
Key features
- 80 GHz FMCW, 4° beam angle
- Measuring range 0.05-30 m, accuracy ±2 mm
- PTFE lens, condensation and build-up resistant
- 4-20 mA with HART 7, RS485 Modbus option
- Process temperature -40 to 200 °C, pressure to 40 bar
- Ex ia IIC T6 intrinsic safety
