Overview
The KANOMAX Model 6332D Thermal Anemometer Transmitter is a precision-engineered environmental monitoring instrument designed for continuous, real-time wind velocity measurement and analog signal transmission in HVAC commissioning, cleanroom validation, duct airflow verification, and industrial ventilation system monitoring. Based on constant-temperature anemometry (CTA), the device measures airflow by detecting convective heat loss from a heated sensing element—typically a platinum resistance wire or thin-film sensor—whose thermal dissipation correlates directly with local air velocity. Unlike mechanical cup or vane anemometers, the 6332D delivers rapid response (<100 ms), minimal flow disturbance, and high repeatability across turbulent and low-velocity airstreams. Its integrated digital display eliminates the need for external readout units, enabling immediate field verification while maintaining full analog output capability for integration into building management systems (BMS), PLCs, or SCADA architectures.
Key Features
- Integrated LCD display showing real-time wind speed (m/s or ft/min) without requiring external meters
- Switch-selectable analog outputs: 4–20 mA, 0–1 V DC, or 0–5 V DC—configured via internal DIP switches for flexible system integration
- Thermally compensated sensor electronics ensuring stable performance across the full operating temperature range (5–40 °C)
- Compact, robust housing (128 × 78 × 30 mm; 320 g) with IP54-rated front panel for dust and splash resistance in demanding laboratory and industrial environments
- Modular probe compatibility—supports interchangeable thermal anemometer probes (e.g., KA01, KA02, KA03 series) optimized for duct, grille, or free-air applications
- No moving parts—ensuring long-term reliability, minimal maintenance, and immunity to mechanical wear or bearing failure
Sample Compatibility & Compliance
The 6332D is compatible with KANOMAX’s full line of calibrated thermal probes, each characterized per ISO 16813:2020 (HVAC air velocity measurement) and traceable to JCSS (Japan Calibration Service System) standards. Probe selection determines effective measurement range and spatial resolution—for instance, the KA03 probe enables high-resolution profiling in laminar flow hoods (down to 0.1 m/s), while the KA01 offers extended range for high-velocity duct testing. The transmitter complies with IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emissions), supporting deployment in electrically noisy industrial settings. While not intrinsically safe, it meets general-purpose safety requirements under IEC 61010-1 for measurement/control equipment used in non-hazardous locations.
Software & Data Management
The 6332D operates as a stand-alone analog transmitter and does not require proprietary software for basic operation. However, when paired with KANOMAX’s optional data logging accessories (e.g., KL-3000 series recorders) or third-party DAQ systems, its analog outputs support time-synchronized acquisition with timestamped traceability. For regulated environments—including pharmaceutical cleanrooms or ISO 14644-certified facilities—the 4–20 mA output may be interfaced with validated control systems compliant with FDA 21 CFR Part 11 (when combined with appropriate audit-trail-capable software and electronic signature protocols). Calibration certificates include uncertainty budgets aligned with ISO/IEC 17025 requirements.
Applications
- HVAC system balancing and air change rate verification per ASHRAE Standard 111
- Cleanroom airflow uniformity mapping and ISO 14644-3 classification testing
- Exhaust hood face velocity validation (e.g., ANSI/AIHA Z9.5, EN 14175)
- Industrial furnace and dryer airflow monitoring
- Wind tunnel calibration reference and boundary layer profiling
- Environmental chamber airflow characterization during thermal stress testing
FAQ
What probe types are compatible with the Model 6332D?
The 6332D accepts all KANOMAX thermal anemometer probes with standard BNC or LEMO connectors, including KA01 (high-velocity duct probe), KA02 (grille probe), and KA03 (low-velocity laminar flow probe). Probe-specific calibration data must be applied manually per manufacturer guidelines.
Can the 6332D be used outdoors?
It is rated for indoor use only (IP54 front panel; no protection against rain or sustained humidity). Ambient temperature must remain within 5–40 °C, and condensation must be avoided.
Is the 4–20 mA output isolated?
Yes—the analog outputs are galvanically isolated from the power supply and sensor circuitry to prevent ground loops and ensure signal integrity in multi-device installations.
How often should the unit be recalibrated?
Annual calibration is recommended for GxP or ISO-compliant applications. Field verification using a NIST-traceable reference anemometer is advised before critical measurements.
Does the display update in real time?
Yes—the LCD refreshes at 2 Hz, providing stable, flicker-free readings suitable for dynamic airflow assessment and operator feedback during system adjustments.
