CERESENSO Disposable Thermocouple Airflow Sensor – Reliable Respiratory Thermal Monitoring
CERESENSO Disposable Thermocouple Airflow Sensors provide a accurate, hygienic solution for detecting nasal and oral airflow changes during Polysomnography (PSG) sleep diagnostic studies. Engineered to meet strict clinical standards, this sensor measures temperature fluctuations between cooler inhaled room air and warmer exhaled breath, providing essential signal traces for scoring Obstructive, Central, and Mixed Sleep Apnea events.
Featuring flexible nasal prongs and an extended oral prong, the sensor covers both nasal and mouth breathing patterns seamlessly. Terminated with standard 1.5mm touch-proof Safety DIN connectors, it connects directly into standard AC airflow channels on major PSG headboxes without needing external batteries or interface amplifiers.
Key Features & Advanced Thermal Sensing Technology
Engineered for hospital sleep laboratories and home sleep apnea testing (HSAT) providers looking for high-accuracy single-use consumables.
- Dual Nasal & Oral Detection: Anatomically shaped housing with dual flexible nasal prongs and a flexible oral drop prong captures temperature shifts from both mouth and nose breathing.
- 100% Single-Patient Use: Eliminates time-consuming sterilization procedures between subjects, ensuring peak clinical hygiene and saving valuable labor hours.
- Plug-and-Play Safety DIN Connectors: Industry-standard 1.5mm touch-proof Safety DIN connectors (color-coded blue/gray) fit securely into standard PSG amplifier inputs.
- Fast Thermal Time Constant: Micro-thermocouple elements respond instantly to breath temperature changes, producing high-resolution, stable waveform outputs.
Patient Comfort & Flexible Ergonomics
Designed to remain securely in position throughout overnight sleep studies without causing skin discomfort or displacement.
- Lightweight Ergonomic Housing: Compact, smooth molded centerpiece rests comfortably under the patient’s nose, preventing irritation during multi-hour sleep studies.
- Pliable Adjustment Prongs: Flexible prongs can be easily positioned close to the nostrils and mouth to maximize thermal signal reception.
- Tangle-Free Ultra-Flexible Lead Wire: High-flex medical wire prevents motion artifacts caused by patient movement in bed and includes an integrated cable manager clip.

Frequently Asked Questions (FAQ)
How does a thermocouple airflow sensor work during a sleep study?
A thermocouple sensor detects temperature differences between ambient air inhaled into the lungs and warm air exhaled from the body. As the patient breathes, the micro-thermocouples generate a micro-voltage signal corresponding to the respiratory rate and waveform, allowing clinicians to score apneas.
Why choose a disposable thermocouple airflow sensor over a reusable one?
Disposable airflow sensors eliminate cross-contamination risks between patients and remove the labor-intensive cleaning and disinfection process after every sleep study. They offer a sanitary, out-of-the-box solution ideal for high-volume PSG laboratories.
Is this sensor compatible with Cadwell, Alice, or SleepSense setups?
Yes. The sensor is fitted with standard 1.5mm touch-proof Safety DIN connectors that plug directly into the AC airflow input ports of Cadwell, Respironics Alice, Compumedics, and SleepSense-compatible headboxes.
Does this thermal airflow sensor require external power or batteries?
No. Thermocouple technology is passive—it converts heat gradients into electrical voltage directly. No external batteries or interface boxes are required.
