Tips: What are the Advantages of Capacitive Level Sensor?

Contactless Operation. Capacitive sensors can detect the water level without direct contact with the liquid. This non-contact feature reduces the risk of sensor contamination or corrosion.
High Sensitivity. Capacitive sensors are highly sensitive to changes in the dielectric constant of the surrounding medium, such as water. This allows for precise and accurate detection of water levels.
Low Maintenance. Since there is no direct contact with the liquid, capacitive sensors typically have lower maintenance requirements. This makes them suitable for long-term and continuous monitoring without frequent calibrations or replacements.
Fast Response Time. Capacitive sensors can provide quick responses to changes in water levels. This is beneficial in applications where rapid detection and response are crucial.

About capacitive level sensor

We are measuring 30 wt% KOH in the pipe, and the wall thickness is somewhere between 2.87 mm to 4.55 mm (depending on 3/4” vs. 1” and schedule 40 vs. 80). 30 wt% KOH has a conductivity of~1.2-1.3 S/cm. The sensor I’m interested in is SKU: ATO-CLS-CE15. Can it be used?

ATO Responded

Sorry, this unit SKU: ATO-CLS-CE15 has a detection distance of only 2mm. If the wall thickness reaches 2.87 mm to 4.55 mm, the sensor can Not measure properly. We recommend the square capacitive proximity sensor, SKU: ATO-SPS-C2010, with a detection distance of 1-10mm. Please check if it meets your requirements, see spec on: https://www.ato.com/square-proximity-sensor-capacitive
