SISCO contact capacitance level transmitter features a corrosion-resistant PEEK and 316L stainless steel design, making it suitable for different working environments. With 100mA maximum output current, IP65 protection, and built-in electrical safety protection, this capacitance liquid level sensor provides a reliable solution for tank monitoring, fluid control, and automation systems.
Material & Structural Advantages
- 316L Stainless-Steel Housing: This contact capacitance liquid level sensor uses a food-grade 316L stainless-steel main body. Better corrosion resistance & anti-oxidation performance than 304 stainless steel, anti-rust for harsh working environments.
- PEEK Front Probe: Food-contact safe PEEK polymer material, high temperature resistance (long-term working up to 260°C), excellent corrosion resistance, widely used in aerospace and medical industries.
- Conical Tip Design: Conical front plug minimizes liquid hanging for the contact capacitance liquid level transmitter, preventing false triggering and poor detection caused by residual liquid.
Detection & Usability Performance
- Adjustable Sensitivity via Potentiometer: Tune sensing sensitivity with built-in potentiometer. Turn counter-clockwise for high-viscosity liquids such as glue and grease; turn clockwise for low-viscosity media including water and oil. Compatible with diverse liquid types.
- Real-time Status LED Indicators: Red LED for power, green LED for signal output. On-site visual status feedback for fast commissioning and troubleshooting of the contact capacitance liquid level sensor.
Applications
Contact capacitance level sensor delivers reliable level monitoring for diversified media, perfectly suited for detecting ink, engine oil, glue, grease, paste substances, pigment, powder and ternary materials; it works stably for both high-viscosity fluids and non-viscous liquids.

Q1: Can the contact capacitance liquid level sensor detect fuel or diesel?
A1: Yes, the contact capacitance liquid level sensor can detect fuel and diesel by measuring capacitance variations caused by liquid level changes. Unlike conductivity-based sensors, this technology works well with non-conductive liquids, including diesel, gasoline, and oil-based fluids. The sensor provides a reliable solution for fuel tank monitoring, industrial equipment, and automatic liquid level control systems.
Q2: Is a contact capacitance liquid level sensor affected by liquid color?
A2: No, a contact capacitance liquid level sensor is generally not affected by liquid color because the detection principle is based on changes in capacitance rather than optical signals. Unlike optical level sensors that may have difficulty detecting dark, colored, or opaque liquids, capacitive sensing technology can reliably monitor materials such as ink, pigment solutions, oil, and other colored liquids. This makes the sensor suitable for industrial applications where liquid appearance varies.
Q3: What makes a contact capacitance liquid level sensor reliable?
A3: A contact capacitance liquid level sensor is reliable because it uses solid-state capacitive sensing technology with no mechanical moving parts, reducing wear and maintenance requirements. The capacitance liquid level sensor provides stable liquid detection through adjustable sensitivity, fast response, and consistent performance with different media, including high-viscosity fluids and non-conductive liquids. Durable materials, electrical protection features, and suitable environmental protection ratings further improve reliability in industrial liquid monitoring applications.
Tips: Can a contact capacitance liquid level transmitter detect high-viscosity liquids?
Yes, a contact capacitance liquid level transmitter can detect high-viscosity liquids such as glue, grease, paste, and slurry because capacitive sensing technology is not dependent on liquid flow speed or viscosity. By detecting changes in capacitance when the medium contacts the sensing probe, the sensor provides stable level detection even for thick and sticky materials. This makes it suitable for industrial applications involving adhesives, coatings, pigments, and other viscous substances.
