Medical and biomedical

Our MEMS-based pressure transducers deliver reliable accuracy and stability in flow measurement applications. Coupled with our disposable dome, which is easily integrated with your existing line sets, our sensors are designed to meet demanding medical and industrial requirements. We have various housing configurations to accommodate machine mounting needs.

Applications: The SP850 series have been integrated by our customers in medical machines for:

• Haemodialysis and Continuous Renal Replacement Therapy (CRRT)
• Cell separation and processing
• Organ transport
• Eye surgery
• Kidney stone surgery

Benefits: Direct flow measurement - High accuracy and stability - Flexible and easy integration - Durability and reliability
