Product Description
Product Overview
The E+E EE381 Online Moisture Testing Machine is specifically engineered for continuous monitoring of water content in transformer and lubrication oils. This advanced equipment ensures optimal performance and preventive maintenance for industrial machinery by providing real-time moisture measurement data.
Key Features
- Continuous online monitoring of moisture in oil
- Measures water activity (aw) and temperature for accurate ppm calculation
- Dual configurable outputs for water activity, content, or temperature
- Two relay outputs for control and alarm functions
- 360° positionable screw connection for flexible mounting
- Stainless steel filter protection for sensor longevity
- IP65 rated housing for industrial environments
Measurement Capabilities
The EE381 transmitter measures water activity (aw) and temperature, then calculates water content in ppm for mineral transformer oils. For non-mineral and lubrication oils, specific oil parameters can be programmed into the device for accurate calculations.
