Moisture in Oil Probes

Moisture in Oil Probes

These smart and robust probes are designed for demanding moisture measurements in transformer and lubrication oils, hydraulic fluids, and other liquids. With over 20 years of sensor technology expertise, it offers exceptional sensitivity and reliability, even in the dry end of the range, making it ideal for critical applications.

Application Features:

• Continuous online measurement for dissolved moisture in oil.
• Measurement range: -70 … +180 °C (-94 … +356 °F).
• Measures water activity (aw), relative saturation (%RS), and temperature (T), with ppm
• concentration calculation for transformer oils.
• Available in two probe lengths: 262 mm (standard) and 448 mm (longer).
• Accuracy up to ±0.02 aw / 2 %RS and temperature accuracy up to 0.1 °C (0.18 °F).
• Traceable calibration certificate included (five points for humidity, one for temperature).
• Modbus RTU over RS-485 for flexible connectivity.
• Compatible with modular transmitters for extended functionality, including data visualization
• and configuration via specialized software.
• Adjustable installation depth with options for ISO 1/2″ and NPT 1/2″ pressure fittings.
