Description

The sensor operates on a capacitive sensing principle, detecting changes in the dielectric constant caused by the presence or absence of liquid on the opposite side of a non-metallic tank wall. This allows for completely contactless level detection without penetrating the container, preserving sterility and preventing contamination or scaling issues common with float-based sensors.

Its solid-state construction ensures long-term reliability with no mechanical parts to stick or fail. The 24V DC supply makes it directly compatible with a wide range of industrial automation and control environments. The sensor is designed for robust performance across various non-conductive fluids and is housed in a durable black casing.

Key Features

  • External Mounting Design: Enables liquid level detection without internal tank contact, ideal for sealed or sterile systems.
  • Solid-State Reliability: No moving parts or mechanical switches eliminates jamming and wear, ensuring consistent operation.
  • Industrial Voltage Compatibility: 24V DC operating voltage interfaces directly with standard PLCs and industrial control modules.
  • Compact Form Factor: Miniature footprint (30mm x 32mm x 10mm) allows installation in tight spaces.
  • Simplified Integration: Pre-attached 35cm cable facilitates quick wiring and connection to control systems.
  • Broad Fluid Compatibility: Robust construction permits use with a wide range of non-corrosive liquids.
  • High-Value Build: Optimized design provides reliable performance for automated liquid management applications.

Applications

  • External level monitoring for water dispensers, coolers, and coffee machines.
  • Non-invasive liquid level control in sealed dehumidifier or HVAC condensate tanks.
  • Fluid management in hydroponic systems and agricultural irrigation controls.
  • Level detection for chemical or oil storage tanks where internal probes are unsuitable.
  • Integration into vending machines and appliance leak prevention systems.

Frequently Asked Questions

What type of tank walls can this sensor be used on?

This capacitive sensor is designed for use on non-metallic tank walls, such as plastic, glass, or composite materials. The wall material must allow the sensor's electric field to penetrate to detect the dielectric change caused by the liquid inside. It cannot function correctly on conductive metal tanks.

How do I wire and interface this 24V sensor with my control system?

Connect the 24V DC supply to the sensor's power wires. The output is typically a switched DC signal (NPN or PNP style open-collector). Connect the output wire to a digital input on your PLC, microcontroller (using a voltage divider if needed for 5V/3.3V logic), or relay. Always refer to the specific wiring diagram for the sensor's output configuration.

Does this sensor require calibration?

Yes, initial calibration is required after mounting. This typically involves setting a detection threshold while the tank is empty and then again when full. The process adjusts the sensor's sensitivity to the specific tank wall thickness and material, ensuring reliable on/off detection at the desired liquid level.

What is the maximum response time of the sensor?

As a solid-state capacitive sensor with no moving parts, its response time is extremely fast, typically in the millisecond range. The limiting factor is often the control system's scan time or the rate of liquid level change, not the sensor's inherent switching speed.
