OPTISOUND 3000 Range

Ultrasonic level transmitters for basic applications with liquids and solids The OPTISOUND 3000 range consists of compact ultrasonic level transmitters designed for basic non-contact level measurement in liquids and solids. They are ideal for applications in open basins, channels, tanks, silos, and conveyors. With ATEX approvals, SIL 2 compliance (3010), and ingress protection up to NEMA 6, these devices are well-suited for water, wastewater, and industrial process environments.

Models

OPTISOUND 3010 For basic applications up to 5 m / 16.4 ft; compact design; suitable for liquids, slurries, pastes, and solids.
OPTISOUND 3020 For basic applications up to 8 m / 26.2 ft (liquids) and 3.5 m / 11.5 ft (solids); robust design for medium-sized tanks and basins.

Features & Options

Ultrasonic, continuous non-contact level measurement
Measurement independent of medium properties (foam, density, temperature changes)
Maintenance-free operation
Resistant to corrosive environments
Profile measurement possible on conveyor belts
Optional mounting bracket for easy sensor alignment
ATEX-approved; SIL 2 safety integrity level (3010)
Ingress protection: IP66/67, NEMA 4/4X/6
