The E+H Prosonic FDU95 Ultrasonic Level Sensor is for continuous, non-contact and maintenance-free level measurement of powdery to coarse bulk materials. The measurement is unaffected by dielectric constant, density or humidity and also unaffected by build-up due to the self-cleaning effect of sensors. Suited for explosion hazardous areas. Maximum measuring range in solids is 45m (148ft).

The sensor features threaded process connections. Temperature range is -40 to 176°F or 302°F (-40 to 95°C or 150°C) depending on version. Pressure range is 10 to 22 psi (0.7 to 1.5 bar). Blocking distance is 0.6m (2ft) standard, 0.7m at 80°C, 0.9m at 150°C. International explosion protection certificates are available for hazardous area installations.
