How to Select Ultrasonic Anemometer Transducers for Harsh Environments? [Dayu Electronics]
When selecting ultrasonic anemometer transducers for harsh environments such as ports or chemical plants, special attention must be paid to corrosion resistance, signal stability, and environmental adaptability. The following are key selection points and considerations:
1. Frequency selection
- High wind speeds (above 30m/s): A 100-125KHz transducer is recommended due to its strong anti-interference capability, suitable for applications with average circuit design.
- Normal wind speeds (within 30m/s): 180-220KHz transducers are more common, suitable for systems with well-designed circuits.
- Extreme wind speeds (e.g., 60m/s): If the circuit is well optimized, 180-225KHz can still be used; otherwise, 100-125KHz is recommended for enhanced stability.
2. Corrosion resistance requirements
- Ports (salt spray environment): Titanium alloy or PVDF transducers, such as DYA-200-01DI, are recommended for excellent corrosion resistance.
- Chemical plants (acid mist, corrosive gases): PVDF-housed transducers (e.g., DYA-200-01DJ) are ideal due to their chemical resistance and high signal strength.
3. Waterproofing and anti-condensation
- Transmitting surface material: Use non-absorbent materials (such as PVDF or specially coated metal) to prevent rain or condensation from affecting the signal.
- Protection rating: At least IP68 to ensure long-term outdoor use without moisture ingress.
4. Installation method
- Port machinery vibration is significant: The transducer should be mountable directly on metal brackets or use rubber vibration isolation sleeves to reduce resonance interference.
Summary
When selecting ultrasonic anemometer transducers for ports or chemical plants, corrosion resistance, waterproofing, vibration resistance, and signal stability are key. PVDF or titanium alloy materials suit corrosive environments, while high sensitivity and wide temperature range ensure long-term reliable operation. It is recommended to consult suppliers (such as Fuzhou Dayu Electronics) for customized selection based on specific working conditions.
