Description

Application

The Prosonic FDU95 ultrasonic sensor provides continuous, non-contact, and maintenance-free level measurement for a range of materials, from fine powders to coarse bulk solids. Its performance is not influenced by the dielectric constant, density, or humidity of the material, and its self-cleaning feature prevents build-up. It is suitable for use in explosion-hazardous environments with a maximum measuring range of 45 meters (148 feet) for solids.

Ideal for measuring levels in silos, conveyors, stockpiles, and crushers, particularly in areas with low structural heights.

Process connection: Thread
Temperature range: -40 to +80°C or up to +150°C (-40 to +176°F or +302°F)
Pressure range: +0.7 to +1.5 bar (+10 to +22 psi)
Maximum measuring range for solids: 45 meters (148 feet)
Blocking distance: 0.7 meters at 80°C (2.3 feet), 0.9 meters at 150°C (2.9 feet)
Certified for international explosion protection standards.

Benefits

Features an integrated temperature sensor for Time-of-Flight correction, ensuring accurate readings even with temperature fluctuations.
Ideal for harsh environments, with remote installation possible at distances of up to 300 meters from the transmitter.
Reduces the formation of build-up thanks to its self-cleaning capability.
Equipped with automatic sensor recognition for easy setup with FMU90/FMU95 transmitters.
Weather-resistant and flood-proof (IP 68).
Non-contact measurement reduces the need for maintenance.
Complies with international Dust-Ex and Gas-Ex certifications for safe use in hazardous environments.
