Non-contact Liquid Level Sensor Stick

Dimensions: 18 x 13 x 11 mm. Weight: lightweight ABS construction. Cable length: 45 cm. Operating voltage: DC 5–24 V. Current consumption: 5 mA. Output signal: digital high/low level (output high = Vin, low = 0 V), output current capacity: 1–100 mA. Response time: 500 ms. Working temperature range: 0–85 °C. Humidity tolerance: 5–100 %. IP65-rated ingress protection. Sensing capability depends on pipe outer diameter and wall thickness — supports non-metal pipes ≥10 mm OD, with maximum detectable wall thickness up to 20 mm (for pipes ≥100 mm OD) down to 1 mm (for pipes ≥10 mm OD). Level measurement error: ±15 mm. Compatible with toxic, strongly acidic, strongly alkaline, and high-pressure sealed liquids without direct contact. No drilling or vessel modification required for non-metal tanks or pipes. This sensor uses advanced signal processing and a high-speed chip to enable true non-contact level detection through container walls. It is mounted externally at high and low positions on the vessel wall — ideal for monitoring fill levels in closed systems. The intelligent design includes level memory and status indication, supporting multi-point series connection for scalable monitoring setups. Suitable for industrial chemical storage, water treatment, DIY automation, food-grade tanks (with compatible non-metal vessels), and laboratory applications where corrosion resistance, safety, and process continuity are critical. Installation requires no penetration, preserving tank integrity and eliminating leakage risk.
