Soliwave FDR57

Summary

Product Identification

• Product Name: Soliwave FDR57, FQR57
• Type: Microwave barrier

Application

The Soliwave FDR57 and FQR57 are used for non-contact level limit detection and bulk flow detection.

• Level Limit Detection: Suitable for bulk solids of all kinds and liquids, as well as for monitoring and counting piece goods. Can be used to detect accumulations or fouling.
• Bulk Flow Detection: Optional monitoring of material movement (movement/no movement) for applications like monitoring shafts or feed hoppers for material flow and backlogs.

Device Properties

• Detection Range:
  • Up to 100 m for level limit detection.
  • Up to 10 m for bulk flow detection (dependent on bulk solids).
• Process Temperature:
  • Up to +70°C (+158°F).
  • Up to +450°C (+842°F) with optional high temperature adapter.
• Process Pressure:
  • Up to 680 kPa (6.8 bar) absolute.
  • Up to 2.1 MPa (21 bar) absolute with optional high pressure adapter.
• Other: Suitable for use under strong continuous vibration load and in hazardous areas (dust and gas).

Key Features & Benefits

• Simple Mounting: Thread options include R 1½, 1½ NPT, or G 1½ (with counter nut).
• Flexible Installation: Electronics housing can be rotated by 360°.
• Robust and Low Maintenance: High mechanical robustness ensures no wear, long operating life, and maintenance-free operation.
• Integrated Power: No separate supply voltage required; powered via the Nivotester FTR525.
• Compatibility: Fully mechanically compatible with previous Soliwave FQR50/FDR50 and FQR56/FDR56 devices.
• Enhanced Reliability: Increased reliability through optional integrated bulk flow detection.
• Versatile Principle: Measuring principle is almost independent of process properties, making it suitable for difficult applications.
• Simple Operation: Easy operation via the FTR525 Nivotester with graphical display.

Measuring Principle

• Level Limit Detection: Emits a microwave signal detected by a transceiver opposite.
• Bulk Flow Detection: Measures the strength of reflected frequency-shifted energy (Doppler effect) from moving bulk solids.

Measuring System

The complete system comprises the FDR57/FQR57 devices and the Nivotester FTR525 remote process transmitter with control unit.

Input Specifications
