Functional Description
Working Principle
The 733910-HEL D-Lite sensor operates on the principle of differential pressure measurement. As air flows through the sensor, it creates a pressure difference across a precision orifice. This pressure differential is converted into an electrical signal that can be processed by connected medical automation systems to calculate:
- Tidal Volume (TV) - Volume of air moved during normal breathing
- Minute Volume (MV) - Total volume of air breathed per minute
- Peak Flow Rates - Maximum airflow during forced expiration
- Flow-Volume Loops - Graphical representation of breathing patterns
Integration with Medical Automation Systems
This sensor integrates seamlessly with various medical automation platforms including:
- Anesthesia Delivery Systems: Monitors patient breathing during surgical procedures
- Mechanical Ventilators: Provides real-time feedback for ventilation control
- Pulmonary Function Testing Equipment: Enables accurate diagnosis of respiratory conditions
- Patient Monitoring Systems: Continuous respiratory monitoring in critical care

Frequently Asked Questions (FAQ)
A: The sensor is primarily designed for GE/Datex anesthesia machines and ventilators, but is also compatible with various other medical equipment that uses standard 22mm/15mm connections for spirometry and flow measurement.
A: As a reusable sensor, it should be inspected before each use and calibrated according to manufacturer recommendations (typically every 6-12 months). The sensor should be replaced if any damage, discoloration, or performance degradation is observed.
A: The sensor is made from medical-grade polyphenylsulfone that can withstand standard sterilization methods including autoclaving (up to 134°C), ethylene oxide gas sterilization, and chemical disinfection with appropriate medical-grade solutions.
A: With proper care and maintenance, the 733910-HEL sensor can last for several years of regular clinical use. The transparent yellow material allows for easy visual inspection of internal components.
A: The sensor provides analog electrical signals that can be connected to PLC analog input modules. These signals are then processed by the PLC to control ventilation parameters, trigger alarms, and provide data for patient monitoring displays.
