Kanomax 6332/6332D Hot-Wire Anemometer Transmitter

Overview

The Kanomax 6332/6332D Hot-Wire Anemometer Transmitter is a precision-engineered environmental monitoring instrument designed for continuous, real-time air velocity measurement in HVAC commissioning, cleanroom validation, laboratory ventilation assessment, and industrial airflow characterization. Operating on constant-temperature anemometry (CTA) principles, the system maintains a heated sensing element at a fixed temperature differential relative to ambient air; convective heat loss—directly proportional to local air velocity—is converted into an electrical signal with high linearity and dynamic response. Unlike cup or vane anemometers, the hot-wire sensor enables low-velocity detection (<0.1 m/s), rapid transient response (<100 ms), and minimal flow disturbance—critical for laminar flow verification and duct traverse applications. The transmitter functions as a centralized signal conditioning and interface unit, accepting input from any of ten standardized Kanomax hot-wire probes (e.g., 6311, 6312, 6313, 6321 series), thereby enabling application-specific configuration without hardware replacement.

Key Features

• Modular architecture supporting 10 interchangeable Kanomax hot-wire probes—each optimized for distinct velocity ranges, temperature limits, and physical constraints (e.g., mini-probes for confined ducts, high-temp probes up to 150 °C, or hygienic stainless-steel variants for pharmaceutical environments)
• Integrated backlit LCD display on model 6332D for on-device real-time readout of wind speed, units, probe ID, and status indicators—eliminating dependency on external data loggers during field calibration or spot checks
• Dual analog output options: factory-configurable 0–5 V DC or 4–20 mA current loop, compliant with standard building management systems (BMS), PLCs, and SCADA architectures
• Multi-unit cascading capability: up to 16 transmitters can be daisy-chained via RS-485 communication (optional module), enabling synchronized multi-point velocity mapping across large HVAC networks or cleanroom ceiling grids
• Ruggedized aluminum alloy housing (IP54-rated enclosure) with compact footprint (128 × 78 × 30 mm) and low mass (320 g), facilitating permanent wall-mount installation or portable deployment with minimal structural impact
• Stable DC 12 V ±2 V power requirement—compatible with uninterruptible power supplies (UPS) and industrial DC distribution panels

Sample Compatibility & Compliance

The 6332/6332D transmitter is compatible exclusively with Kanomax-certified hot-wire probes, ensuring traceable calibration and metrological integrity. Each probe undergoes individual NIST-traceable calibration at three points across its operational range, with certificate documentation provided per unit. The system supports compliance-critical workflows in regulated environments: probe interchangeability is validated per ISO 14644-3 Annex B for cleanroom airflow uniformity testing; analog outputs meet IEC 61000-6-2/6-4 immunity and emission standards; and firmware design facilitates audit-ready operation under GLP and GMP frameworks when paired with Kanomax’s optional data logging software (Kanomax AirFlow Suite). While not intrinsically rated for hazardous locations, stainless-steel probe variants (e.g., 6313-S) are suitable for ISO Class 5–8 cleanrooms per ISO 14644-1 and EU GMP Annex 1 requirements.

Software & Data Management

The transmitter operates standalone but integrates seamlessly with Kanomax AirFlow Suite (Windows-based), enabling time-synchronized multi-channel acquisition, automated duct traverse reporting (per ASHRAE 111 and ISO 16813), and export to CSV, PDF, or XML formats. The software supports configurable alarm thresholds, trend visualization over 24+ hours, and digital signature-enabled report generation compliant with FDA 21 CFR Part 11 requirements when deployed with user authentication and audit trail modules. Raw analog outputs are compatible with third-party DAQ systems (e.g., National Instruments, Keysight) via standard voltage/current input channels—no proprietary drivers required.

Applications

• HVAC system balancing and TAB (Testing, Adjusting, Balancing) per ASHRAE Guideline 1 and NEBB Procedural Standards
• Cleanroom airflow visualization and ISO 14644-3 certification—including vertical/horizontal unidirectional flow mapping and turbulence index evaluation
• Pharmaceutical facility environmental monitoring (EM) programs, particularly for Grade A/B zone supply air velocity qualification
• Industrial fume hood face velocity verification per ANSI/ASHRAE 110 and EN 14175
• Research-grade boundary layer studies in wind tunnels or climate chambers where spatial resolution and temporal fidelity are essential
• Energy efficiency audits involving duct leakage quantification and fan performance curve analysis

FAQ

Does the 6332D require recalibration after probe interchange?
No—each probe contains embedded calibration coefficients readable by the transmitter via its digital interface; automatic parameter loading ensures measurement continuity without manual reconfiguration.
Can the analog output be scaled to custom velocity ranges?
Yes—output scaling is programmable via front-panel menu (6332D) or AirFlow Suite software, allowing linear mapping of full-scale output to any sub-range within the probe’s certified span.
Is the unit suitable for outdoor or high-humidity environments?
The transmitter body meets IP54 ingress protection; however, probe selection must match environmental conditions—e.g., use hydrophobic-coated probes (6321-H) for high-humidity or condensing applications.
What is the maximum cable length between probe and transmitter?
Standard shielded twisted-pair cables support up to 30 m; extended runs up to 100 m are achievable using low-capacitance, double-shielded cabling and noise-suppression ferrites.
Are calibration certificates supplied with each probe?
Yes—each probe ships with a NIST-traceable calibration certificate listing serial number, date, reference standard, uncertainty budget, and measured deviation across three velocity points.
