EE364 Moisture in Oil Sensor for Compact Hydraulics & OEMs

Space is tight in hydraulic power packs and gearboxes. Yet, water contamination remains a major threat. You need a sensor that fits anywhere but delivers professional data. The Nuicon EE364 Moisture in Oil Sensor is the compact answer. Designed for tight integration into mass-produced hydraulic systems and lubrication skids, this miniature probe continuously monitors Water Activity (aw) and Temperature. It detects water ingress early, preventing corrosion and oil degradation before your machinery fails.

Moisture in Oil Sensor – Key Features

OEM-Friendly Design: Compact size with standard G ½” ISO thread for easy installation in tanks and lubrication systems.

Dual Measurement Output

Simultaneously measures water activity (aw) and temperature via two 4–20 mA outputs.

High Measurement Accuracy

Capacitive sensing element ensures reliable readings even in aged or contaminated oil.

Rugged Construction

Stainless steel housing (up to 20 bar) with IP65 connector for harsh environments.
