Air Velocity Transducers

Continuous airflow visibility is essential for stable production, efficient energy use, and consistent environmental conditions. TSI air velocity transducers convert airflow into dependable signals that your control system can act on. From low-velocity make-up air to high-flow exhaust, these sensors deliver the data required to maintain targets and respond quickly to changes.

What sets TSI transducers apart:

• High sensitivity and stability: Thermal dispersion technology excels at low velocities while covering a broad range, enabling one platform across diverse applications.
• Temperature compensation: Electronics adjust for temperature changes to maintain signal consistency across seasonal and process variations.
• Fast dynamic response: Captures real-time airflow fluctuations for tighter control of dampers, fans, and VFDs.
• Control-ready outputs: Select from common analog outputs such as 0–10 V or 4–20 mA and available digital options for BAS/DCS integration.
• Configurable probes: In-duct and remote probe styles support optimal placement in round or rectangular ducts and near hoods or filter banks.
• Industrial durability: Robust housings, mounting hardware, and protective features support long service in plant environments.

Use cases across manufacturing:

• Supply and return air monitoring: Maintain ventilation baselines and verify airflow delivery to critical zones.
• Process exhaust control: Provide feedback to VFDs and dampers for welding, coating, or chemical exhaust systems.
• Filter and media performance trending: Track velocity changes to help schedule maintenance and manage pressure drop.
• Laminar flow and clean areas: Monitor low velocities over equipment and workstations to support quality protocols.
• Energy optimization: Feed data into demand-based ventilation strategies to help reduce energy consumption while meeting performance targets.

Installation and integration best practices:

• Place probes in locations with developed flow profiles and adequate straight runs to improve measurement repeatability.
• Use averaging locations or multiple sensors as needed for large ducts or complex geometry.
• Select outputs and scaling to match BAS/DCS input ranges and resolution for stable control.
• Plan cable routing, shielding, and grounding to minimize noise in high-interference areas.

Quality and calibration:
TSI offers calibration services and documentation to support internal quality systems. Routine calibration helps maintain measurement confidence over the sensor’s service life.

Results you can apply:

• Tighter control of airflow setpoints supports consistent production and product quality.
• Trends and alarms help teams investigate deviations sooner and reduce unplanned downtime.
• Accurate airflow data supports verification activities related to ventilation guidance and audits.
