Air Velocity Transducers

In life sciences, airflow is not just a commissioning parameter — it is an ongoing control variable. TSI air velocity transducers deliver steady, actionable data that helps facilities monitor laminar flow, maintain directional airflow, and support cleanroom performance targets between certification cycles.

Designed for Integration

• Standard analog outputs (such as 0–10 V or 4–20 mA) connect to building automation systems, data loggers, or process controllers.
• Probe options fit ducts, plenums, and work zones to capture representative velocity data without obstructing flow.
• Temperature compensation helps stabilize readings across ordinary room fluctuations, supporting trend continuity.

Where They Add Value

• Cleanrooms: Track supply diffuser velocity to trend filter loading and inform maintenance planning.
• Laminar flow benches: Maintain setpoints for product protection by feeding feedback loops with real-time data.
• Biosafety cabinets: Monitor inflow/downflow zones to support cabinet performance tracking between certifications.
• Isolators and enclosures: Trend airflow to support containment strategies and SOP verification.
• HVAC control: Provide duct velocity inputs for volumetric flow calculations and energy optimization.

Quality and Documentation

• Factory calibration and service options help align sensors to your quality program. Certificates with traceable references support audit-ready documentation.
• Long-term trending generates evidence for periodic reviews and continuous improvement initiatives.

Selection Considerations

• Velocity range and sensitivity for the application (low-velocity laminar versus higher duct flows).
• Probe geometry and mounting hardware for ducts, diffusers, or localized zones.
• Output type and scaling compatible with your BMS or PLC.
• Environmental conditions including temperature, humidity, and cleanliness.

Operational Tips

• Place sensors where flow is fully developed to improve measurement repeatability.
• Use consistent orientation and shield sensors from direct disturbances (e.g., near doors or occupants).
• Pair with differential pressure sensors and particle monitoring to build a fuller environmental picture.

By combining stable sensing technology with easy integration, TSI air velocity transducers help life science facilities automate, document, and optimize airflow performance. The result is better visibility into cleanroom and process conditions, timely maintenance decisions, and data that supports compliance objectives over the equipment lifecycle.
