Engineer's Essential Guide: Selecting Non-Contact Level Sensors to Replace Float Switches
1.
Tank Material & Wall Thickness (Most Critical) •
Metallic Tank: Can directly use standard XINGKECHUANG non-contact sensors adhered externally. High sensitivity. •
Non-Metallic Tank (e.g., PP, PC): Prioritize XINGKECHUANG sensors optimized for non-metallic containers or use a split design (probe + controller). Note wall thickness; generally ≤4mm is ideal for good sensitivity.
2.
Output Signal Requirement •
Digital Signal (High/Low Level): For simple low-water/full-tank alerts, pump start/stop control. Most common type, directly replaces float switch function. •
Analog Signal (e.g., 0-5V, 4-20mA): For smart devices needing continuous level monitoring, enabling real-time remaining water display.
3.
Supply Voltage (VCC) •
Confirm the voltage range available on your mainboard (e.g., 5V DC, 12V DC, 24V DC). XINGKECHUANG sensors support wide voltage input for strong compatibility.
4.
Electrical Interface & Cable Length •
Choose the required connector type (e.g., pluggable terminal, direct leads) and cable length for easy wiring.
5.
Ingress Protection (IP) Rating •
For environments potentially exposed to moisture (e.g., under-sink), select a model with a suitable IP rating (e.g., IP67).
1.
Define Requirements: List your specific needs based on the five factors above. 2.
Consult XINGKECHUANG: Provide your requirements list to our technical support team. We have a wide range of products to recommend the best-fit model. 3.
Request Samples for Testing: XINGKECHUANG encourages and supports sample testing, the best way to validate your selection. 4.
Small Batch Trial Run: After successful testing, proceed with a small pilot production to further verify production consistency and batch stability.
•
Q: How to detect level in thick-walled non-metallic tanks? •
A: XINGKECHUANG offers high-sensitivity models or internal probe-style sensors to address this.
•
Q: Any requirements for sensor mounting position? •
A: Avoid tank reinforcement ribs, corners, or uneven areas. Choose a flat spot with uniform wall thickness.
•
Q: Is it compatible with existing control programs? •
A: For digital output sensors, the electrical interface is generally compatible with float switches, often allowing direct replacement without program changes.
