Contamination monitor OS 120

Product overview
The OS 120 residual oil sensor provides continuous monitoring of oil vapor content in compressed air and technical gases. The PID-based sensor features automatic calibration for improved accuracy and long-term stability. Sensor contamination and remaining sensor lifetime are continuously monitored and displayed to the operator. On detection of over-range events the sampling air is automatically diverted to protect the detector. Its compact inline design and straightforward installation suit permanent process monitoring in industrial compressed air systems.

Applications

• General compressed air systems
• Downstream of activated carbon filters
• Downstream of oil-free compressors after dryers
• Where upstream drying and filtration are applied

Characteristics

• 5" color touch screen for local display and operation
• PID (photoionization detector) sensing for oil vapor detection
• High-capacity data logger (up to 100 million values)
• Automatic sensor calibration for consistent measurement accuracy
• Real-time sensor contamination and lifetime monitoring with user display
• Over-range protection: sampling air removal to prevent contamination
• Inline continuous monitoring with simple installation
