CERESENSO PSG Body Position Sensor – Precise Postural Sleep Apnea Monitoring
CERESENSO PSG Body Position Sensors provide a highly accurate, durable solution for continuous patient posture monitoring during Polysomnography (PSG) sleep studies. Engineered specifically to diagnose Positional Sleep Apnea (PSA) and sleep-disordered breathing related to body orientation, this sensor reliably identifies five distinct body positions: Supine, Prone, Left Side, Right Side, and Upright.
Designed for seamless integration with Nihon Kohden sleep systems, SleepSense-compatible setups, Cadwell, Alice, and Compumedics PSG headboxes, the sensor features standard 1.5mm touch-proof Safety DIN connectors. Unlike disposable or sealed sensors that require complete replacement when depleted, this unit utilizes an easily accessible compartment for a standard 3V lithium coin cell battery, providing years of reliable service in high-volume sleep laboratories.
Key Features & Advanced Postural Sensing Architecture
Engineered for hospital PSG diagnostic labs, outpatient sleep centers, and medical device distributors seeking reliable, cost-effective sleep accessories.
- Accurate 5-Position Detection: Measures gravity-based axis changes to output precise voltage levels corresponding to Supine, Prone, Left, Right, and Upright positions.
- Replaceable 3V Coin Cell Battery: Uses a standard replaceable 3V lithium battery, eliminating total-unit replacement costs and providing extended operational life.
- Nihon Kohden Compatible Interface: Plug-and-play output formatting for direct channel input on Nihon Kohden PSG amplifiers and standard DIN PSG headboxes.
- Clear Body Orientation Labeling: Features a permanent graphic icon showing “Right (R)” and “Left (L)” torso orientation to ensure fast, error-free technician setup.
Patient Comfort & Secure Clinical Attachment
Designed to remain locked in position throughout overnight testing without slipping or causing discomfort.
- Integrated Velcro Belt Slot: Slips smoothly onto chest or RIP effort belts, holding the sensor firmly flat against the sternum.
- Smooth Ergonomic Plastic Module: Soft-contoured gray enclosure prevents pressure spots on the chest wall when sleeping prone or turning.
- High-Flex Shielded Lead Cable: Lightweight, strain-relieved lead wire prevents signal dropouts and motion artifacts caused by patient turning.
Broad Applications in Sleep Diagnostics
Ideal for hospital sleep labs, private diagnostic sleep centers, home sleep testing (HSAT) providers, and medical supply distributors.
- In-Lab Overnight Polysomnography (PSG) Body Position Recording
- Positional Obstructive Sleep Apnea (POSA) Diagnostic Scoring
- REM Sleep vs. Posture-Dependent Apnea Index (AHI) Correlation
- Direct OEM Replacement for Nihon Kohden & SleepSense 1563 Position Sensors

Frequently Asked Questions (FAQ)
How does this body position sensor output position data to the PSG amplifier?
The internal gravity-sensing tilt mechanism changes its electrical output signal depending on sensor orientation. It generates distinct, predefined DC voltage levels corresponding to Supine, Prone, Left, Right, and Upright positions, which are translated into position channels on your PSG software.
Is this position sensor compatible with Nihon Kohden sleep diagnostic systems?
Yes. The sensor is engineered to match the signal output levels and connector pinout required by Nihon Kohden PSG amplifiers as well as standard 1.5mm Safety DIN headbox inputs.
How do I replace the battery in this position sensor?
The back panel of the sensor module opens easily to allow battery replacement. Simply slide out the depleted 3V lithium coin cell (CR2032/CR2025) and insert a new battery to restore full functionality.
Where should the body position sensor be placed during a PSG test?
The sensor should be secured to the center of the patient’s chest (over the sternum) using the integrated belt loop attached to the thoracic effort belt. Make sure the front indicator diagram correctly faces forward and aligns with the patient’s Right (R) and Left (L) sides.
