Product Line
Capacitive Level Sensors
Non-invasive capacitive level sensors detect liquid through non-conductive vessel walls without any penetration or fluid contact. The CQV1000 provides 100 mm of continuous level measurement with a 4-20 mA output. The CPS provides point-level full/empty detection — both ideal for single-use systems, disposable vessels, and sealed containers.
Featured Model
Model CQV1000
Continuous Capacitive Level Sensor
The CQV1000 mounts on the outside of a non-conductive vessel and senses liquid level through the vessel wall using an alternating electric field. As liquid level changes, the dielectric constant in the sensing field shifts proportionally, producing a linear 4-20 mA output. 100 mm sensing range, no penetration required — ideal for disposable bioreactor bags, sealed process vessels, and reagent containers.
