Lanbao CE15 Pipeline Liquid Level Capacitive Sensor Family

Lanbao CE15 Pipeline Liquid Level Capacitive Sensor Family

The Lanbao CE15 family is a clamp-on capacitive liquid level sensor series designed for non-metal pipelines with outer diameters from 12mm to 26mm. Instead of contacting the media directly, CE15 detects liquid through the pipe wall, making it a practical choice for compact fluid systems that need simple presence or level-state feedback without intrusive probes. For smaller tubing, the Lanbao CE10 family is the more suitable companion range.

CE15 uses a curved body for easier installation on round non-metal tubing and is offered in NPN or PNP outputs with normally open or normally closed logic. This makes it suitable for OEM machinery, beverage equipment, coolant lines, reagent delivery units, and compact dosing systems where integrators need a stable switching signal, 10V to 30V DC operation, and straightforward PLC or controller integration.

Compared with intrusive float or probe-based level sensing, CE15 helps simplify sanitation-sensitive or maintenance-sensitive designs because the sensor is mounted outside the pipe. Final switching performance still depends on the actual tube material, wall thickness, media dielectric behavior, and mounting condition, so real-process validation remains important during machine commissioning.

Board Layout & Label Guide

• Curved Clamp-On Body The CE15 housing is shaped for external mounting on round non-metal pipelines, simplifying installation on compact fluid lines.
• Non-Contact Sensing Principle Liquid is detected through the non-metal pipe wall, so the sensor does not need to contact the media directly.
• Pipe Diameter Window This family is designed for non-metal pipelines with outer diameters from 12mm to 26mm and wall thickness up to 1.0mm.
• Switch Output Variants Model options cover NPN or PNP outputs with normally open or normally closed logic.
• 2m PVC Cable The cable connection supports direct wiring into PLC inputs, relays, or industrial controller terminals.
• Yellow Status LED The output indicator helps technicians verify switching state during installation and troubleshooting.
• Protective Electronics The sensor includes short-circuit, overload, and reverse-polarity protection to improve installation resilience.
• IP67 Housing The enclosure is intended for industrial environments where splash resistance and dust protection are needed.

Supported Devices & Electrical Integration

• PLC Digital Inputs CE15 is suitable for 10V to 30V DC industrial control circuits using NPN or PNP switching signals.
• OEM Fluid Equipment It can be integrated into beverage, coolant, reagent, dosing, and compact process-liquid systems.
• Industrial Controllers The sensor works well where a simple liquid presence or level-state signal is enough.
• Non-Metal Pipeline Assemblies It is intended specifically for external detection on non-metal pipe walls rather than metal tubing.
• Machine Builders and Retrofit Projects CE15 is a good fit for designs that want simpler installation than intrusive probes or wetted components.

Application Scenarios

1. Beverage and Water Dispensing Equipment

CE15 can be mounted on non-metal feed lines to confirm liquid presence in compact dispensing or transfer systems without opening the fluid path.

2. Coolant and Chemical Dosing Lines

The clamp-on structure makes it useful for equipment that needs external liquid-state monitoring on non-metal process tubing.

3. Laboratory and Reagent Handling Systems

It is suitable for compact analyzers and dosing modules where direct media contact should be minimized.

4. OEM Process Skids

Machine builders can use CE15 when they need straightforward level-state or liquid-presence detection on non-metal pipelines.

5. Maintenance-Sensitive Fluid Modules

Because the sensor is mounted externally, it can help simplify service and reduce concerns about wetted probes in some system designs.

FAQ

Q: What pipe size is CE15 designed for?
A: CE15 is intended for non-metal pipelines with outer diameters from 12mm to 26mm and wall thickness up to 1.0mm.

Q: Does the sensor touch the liquid directly?
A: No. CE15 is a clamp-on capacitive sensor that detects liquid through the non-metal pipe wall.

Q: Can it be used on metal piping?
A: No. The documented application is non-metal pipeline detection.

Q: What output types are available?
A: The family includes NPN and PNP versions with normally open or normally closed logic depending on the exact part number.

Q: What voltage does CE15 require?
A: The specified supply range is 10 to 30 VDC.

Q: What are the main protective features?
A: CE15 includes short-circuit, overload, and reverse-polarity protection and uses an IP67-rated housing.

Q: When should I choose CE15 instead of CE10?
A: Choose CE15 for larger non-metal tube diameters in the 12mm to 26mm range. For smaller tubing, CE10 is the better fit.

Q: Do I still need to validate the application on the real machine?
A: Yes. Final switching performance depends on pipe material, wall thickness, media properties, and real installation conditions.
