FTE31 Rotary Paddle Level Switch Working Principle
The FTE31 uses a synchronous motor to drive the paddle to rotate. When the paddle contacts the material, it is blocked, and the drive shaft generates a reaction force that triggers a micro switch, outputting a switching signal. This principle makes the FTE31 suitable for harsh working conditions such as high dust and high temperature, and it has strong anti-interference ability.
Core Advantages
- High Reliability: Mechanical detection, not affected by material dielectric constant or humidity.
- Wide Applicability: Can measure powdery, granular, and blocky solid materials.
- Flexible Installation: Supports top, side, or inclined installation.
- Easy Maintenance: Simple structure, no frequent calibration required.

FTE31 Installation and Commissioning Steps
Correct installation is key to ensuring long-term stable operation of the rotary paddle level switch. Please follow these steps:
- Confirm installation position: avoid the feed inlet to prevent material from directly impacting the paddle.
- Choose installation method: top vertical installation or side horizontal installation; for inclined installation, adjust the paddle angle.
- Fix process connection: tighten threaded or flange bolts to ensure sealing without leakage.
- Wiring: connect power and output signal lines according to the manual, and pay attention to grounding.
- Commissioning: after power-on, observe paddle rotation; manually blocking the paddle should trigger the switch signal.
- Operation check: after feeding material, verify whether the alarm action is normal.
FTE31 Selection Precautions
Different working conditions have greatly different requirements for rotary paddle level switches. During selection, focus on the following aspects:
- Material Characteristics: Density, particle size, and adhesion affect paddle shape and motor torque.
- Process Temperature and Pressure: High-temperature or pressurized conditions require corresponding specifications.
- Explosion-proof Requirements: Explosive environments require explosion-proof FTE31.
- Output and Power Supply: Match with PLC or DCS system.
- Installation Space: Confirm insertion depth and paddle rotation radius.
Common Faults and Maintenance
The FTE31 has a simple structure and low failure rate. Common problems include paddle jamming, motor not rotating, or false signal alarms, usually caused by material adhesion, loose wiring, or abnormal voltage. Regularly cleaning the paddle, checking wiring, and verifying the power supply voltage can effectively extend the service life.
