Kanomax 6332D Hot-Wire Anemometer Transmitter

Overview

The Kanomax 6332D Hot-Wire Anemometer Transmitter is an industrial-grade environmental monitoring instrument engineered for precise, real-time wind velocity measurement and analog signal conversion in HVAC commissioning, cleanroom validation, duct traverse studies, and laboratory airflow characterization. Based on constant-temperature anemometry (CTA), the system employs a thermally sensitive platinum wire sensor housed within interchangeable probe assemblies; airflow cools the heated element proportionally to velocity, enabling high-resolution dynamic response across turbulent and laminar flow regimes. Unlike cup or vane anemometers, the hot-wire principle delivers sub-second response time (<100 ms), low starting threshold (0.1 m/s), and insensitivity to flow direction—critical for applications involving low-velocity recirculation zones or complex duct geometries. The 6332D functions as both a standalone readout device and a field-deployable transmitter, converting measured velocity into standardized analog outputs suitable for integration with building management systems (BMS), data loggers, PLCs, and SCADA architectures.

Key Features

• Integrated backlit LCD display for direct local readout of instantaneous wind speed (units: m/s or fpm), with automatic range scaling based on connected probe specifications
• Switch-selectable analog output configuration: user-configurable via internal DIP switches to deliver 0–5 V DC, 0–1 V DC, or 4–20 mA signals—each linearly proportional to full-scale wind speed (0–50 m/s)
• Modular probe architecture supporting 10 Kanomax-certified hot-wire probes (e.g., straight, bent, telescopic, and ultra-thin variants), all sharing mechanical and electrical compatibility with the 6332D housing
• Robust aluminum alloy enclosure rated IP54 for dust and splash resistance, optimized for installation in mechanical rooms, air handling units, and ceiling plenums
• Low-power design operating from a stable 12 V DC ±2 V supply, minimizing thermal drift and enabling long-term unattended operation when paired with regulated power sources
• Multi-unit cascading capability via synchronized analog output routing, allowing scalable deployment of up to 16 channels without external multiplexing hardware

Sample Compatibility & Compliance

The 6332D is compatible exclusively with Kanomax’s proprietary 6332-series hot-wire probes, each calibrated traceably to JIS Z 8000 and NIST-traceable reference standards. Probe selection determines effective measurement range, spatial resolution, and thermal inertia—e.g., the 6332-0110 (straight probe) offers optimal accuracy in open-space ambient monitoring, while the 6332-0120 (bent-tip probe) enables access to confined ductwork or filter bank arrays. The instrument meets IEC 61000-4 electromagnetic immunity requirements for industrial environments and complies with ISO 14644-3 Annex B for cleanroom airflow uniformity testing. Its analog output stability and linearity support validation under ISO/IEC 17025-accredited laboratories performing HVAC performance verification per ASHRAE Standard 111 and EU GMP Annex 1 guidelines.

Software & Data Management

While the 6332D operates autonomously without host software, its analog outputs are fully compatible with third-party data acquisition platforms including National Instruments LabVIEW, Keysight PathWave, and Siemens Desigo CC. When integrated into continuous monitoring systems, the 4–20 mA output supports loop-powered remote sensing over distances up to 300 m using standard 22 AWG twisted-pair cable. For auditability, users may configure external dataloggers to record timestamped voltage/current values alongside environmental metadata (e.g., temperature, humidity), satisfying FDA 21 CFR Part 11 requirements for electronic records when paired with appropriate system validation protocols. Firmware updates are not supported—the unit relies on factory calibration stability verified during biannual recalibration intervals recommended by Kanomax Technical Support.

Applications

• HVAC system balancing and TAB (Testing, Adjusting, and Balancing) in commercial and pharmaceutical facilities
• Cleanroom ISO Class certification per ISO 14644-1, including unidirectional airflow velocity mapping at supply diffusers and return grilles
• Filter integrity testing and face velocity verification across HEPA/ULPA banks in biosafety cabinets and isolators
• Industrial ventilation assessment in welding booths, paint spray enclosures, and fume hood exhaust systems
• Research-grade boundary layer analysis in wind tunnel test sections and aerodynamic development labs
• Environmental chamber airflow uniformity qualification for stability testing per ICH Q1A(R2) and USP

FAQ

Is the 6332D suitable for outdoor use?
No—the specified operating temperature range (5–40 °C) and IP54 rating restrict deployment to indoor, climate-controlled environments. Outdoor applications require weatherproof enclosures and temperature-compensated probes not supported by this model.
Can the 6332D store measurement data internally?
No—it lacks onboard memory or USB/SD interfaces. Data persistence requires connection to an external logger or SCADA historian.
What recalibration interval does Kanomax recommend?
Annual calibration is advised for routine QA/QC use; semi-annual calibration is required for GLP/GMP-regulated environments per Kanomax Service Bulletin AN-6332-REV2.
Does the 6332D support digital communication protocols such as Modbus or BACnet?
No—it provides analog-only outputs. Digital protocol support requires integration via third-party analog-to-Modbus gateways or dedicated Kanomax data acquisition modules (e.g., 6501 Series).
