High Precision

CLS Capacitive Sensors

Unlike reed sensors, the CLS series uses capacitance technology for continuous, high-precision measurement (Resolution < 1mm). Best for tall tanks or when length customization is needed.

Key Feature: Cut-to-Length

Distributors can stock long units and cut them to size. Calibration is done via external calibrator.

Specifications

Length: 200mm – 1500mm
Output: 0-5V / RS485 / RS232
Accuracy: < 1.0%
IP Rating: IP65
