- Weight:
- 0.00 Grams
Description
Application
The Prosonic FMU42 Ultrasonic Level Sensor is designed for non-contact level measurement across a variety of media, including liquids, pastes, and coarse bulk materials, as well as for flow measurement in open channels or at weirs. Its versatile two-wire or four-wire configuration makes it suitable for use in storage tanks, with agitators, on stockpiles, and on conveyor belts. The sensor features an on-site display that can visualize the envelope curve for straightforward diagnostics. Additionally, it offers a linearization function (up to 32 points) to convert measured values into units of length, volume, or flow rate.
- Measurement Type: Continuous non-contact level and flow measurement
- Process Connection: Flange
- Temperature Range: -40 to +80°C (-40 to +176°F)
- Pressure Range: +0.7 to +2.5bar (+10 to +36psi)
- Max Measuring Distance: 10m (33ft) for liquids, 5m (16ft) for solids
- Blocking Distance: 0.4m (1.3ft) for both liquids and solids
- Certifications: International explosion protection certificates
Benefits
- Reliable Performance: Ensures accurate non-contact measurement.
- Easy Setup: Quick and straightforward commissioning with a menu-guided on-site operation, available in seven selectable languages.
- Diagnostic Display: On-site display of envelope curves enables easy troubleshooting.
- Durable Design: Hermetically sealed and potted sensor provides long-term reliability.
- Chemical Resistance: Made from PVDF, the sensor is resistant to chemical exposure.
- Efficient Calibration: Allows calibration without the need for filling or emptying the tank.
- Automatic Temperature Compensation: Integrated temperature sensor adjusts for variations in sound velocity due to temperature changes.
