MDS-601B 6-Parameter Oil Condition Sensor
MDS-601B 6-Parameter Oil Condition Sensor
-Product Overview-
Real-Time, Multi-Parameter Oil Condition Monitoring for Predictive Maintenance
The MDS-601B 6-Parameter Oil Condition Sensor is an advanced online monitoring instrument designed for industrial lubrication systems. Integrating piezoelectric resonant MEMS technology, dielectric constant sensing, and polymer thin-film capacitive humidity measurement, this sensor delivers real-time, simultaneous measurement of six critical parameters: temperature, dynamic viscosity, density, dielectric constant, water activity, and micro-water content.
By transitioning oil monitoring from periodic sampling to continuous online measurement, the MDS-601B enables early detection of oil degradation and potential equipment faults—helping operators move from reactive to predictive maintenance strategies.
-Key Features & Benefits-
Comprehensive Multi-Parameter Output
Simultaneously measures six key oil condition indicators. The correlation of multi-dimensional data enables a complete, holistic assessment of oil health status—far beyond what single-parameter sensors can provide.
Piezoelectric Resonant MEMS Technology
The core resonator derives density and dynamic viscosity through variations in resonant frequency and quality factor (Q-factor). With no moving parts, the sensor ensures long-term operational reliability and maintenance-free performance.
Polymer Thin-Film Moisture Sensing
Micro-water detection is achieved through dielectric changes in a specialized polymer membrane upon moisture adsorption, offering high sensitivity to trace water content in oil—critical for preventing corrosion and lubricity loss.
Multi-Oil Matrix Calibration & Temperature Compensation
Calibrated across a broad matrix of oil types with an embedded dynamic temperature compensation algorithm that effectively suppresses thermal drift, ensuring data consistency across varying operating conditions.
Industrial-Grade EMI Protection
Equipped with electromagnetic interference (EMI) shielding and an isolated power supply module, the sensor performs reliably in harsh electrical environments—including variable-frequency drive (VFD) interference and high-power start/stop transients.
Easy Installation & Digital Connectivity
Features standard threaded process connections (M39 × 1.5 mm) and supports RS485 MODBUS RTU (default) or CAN digital communication interfaces for seamless integration into existing condition monitoring systems
