The S120-PM-ATEX provides real-time, continuous tracking of lubricant health directly inside critical machinery operating in hazardous zones. Using advanced electrochemical and thermodynamic technology, this sensor measures changes in the oil’s chemical structure, water saturation percentage, and precise temperature. It detects oil aging, oxidation, and coolant leaks long before physical damage occurs. Housed in a heavy-duty, explosion-proof enclosure, the sensor seamlessly integrates into standard plant control systems via industrial analog outputs, eliminating the need to halt operations or obtain hot-work permits for regular oil inspection routines.
To help you successfully implement hazardous-zone oil monitoring across your facility, I-care engineers are available to provide professional support. Our experts offer technical advice on proper sensor positioning inside gearboxes, calibrating baseline parameters for specific oil types, and integrating live sensor data into your automated plant alarms. By combining the S120-PM-ATEX sensor with I-care’s engineering guidance, you can securely extend oil drain intervals, maximize machinery runtime, and maintain strict plant safety standards.
