Solids applications
Rosemount 5402 Non Contacting Radar level transmitter provides industry leading
measurement capabilities and reliability on solids.
Characteristics include:
4 inch cone antenna (4S, 4H, 4M or 4N)
Measurement accuracy: Application dependent
Measurement independent of dust (may need air purging

3 ft (1 m)
2.0 66 ft (20 m)
(2) Measuring range may be reduced by steep inclining surfaces and a combination of dust and condensation. For low dielectric constants and /or
long ranges consider the Rosemount 5303 guided wave radar or the Rosemount 5708 3D solids scanner.

Note
Transition zones are areas where
measurements are not recommended.
The transition zone for Rosemount
5402 in solids mode is 3 ft (1 m).
