Keller Surface Level Sensor

Keller PR-46 X Surface Level Sensor for accurate measurement of surface water. This Swiss made sensor combines high precision and reliability. Accuracy as a result of a ceramic measuring cell for low pressure ranges and µP-electronics for level monitoring. 10 m of Kevlar Cable is supplied with every sensor. Also Keller PR-46 X sensors are compatible with Van Walt telemetry. Therefore Keller PR-46X water level sensors deliver high accuracy for surface water level monitoring. So is a the preferred choice for monitoring surface water. High precision and reliability from Europe’s leading manufacturer of pressure transducers.
