Air Flow Transducer Model 6333
Compact stationary anemometer for remote monitoring of air velocity, temperature and humidity. Model 6333 supports 15 interchangeable probe types, switchable analogue output and RS-485 communication for equipment, facility and IoT monitoring installations.
Model and Probe Overview
| Component | Measurement capability | Range / configuration | Selection guidance |
|---|---|---|---|
| 6333-00 main unit | Stationary transmitter with analogue and digital outputs | 12–24 V DC; switchable 4–20 mA or 0–5 V; RS-485 | Select the probe, cable length, power option and mounting accessories for the installation. |
| Velocity probes | Directional or omnidirectional air-velocity measurement | 0.01–25.0, 30.0 or 50.0 m/s depending on probe | Choose by velocity range, directivity, response time, temperature resistance and probe geometry. |
| Velocity + temperature probes | Simultaneous velocity and temperature measurement | Up to 100°C or 120°C depending on probe | Suitable where process-air temperature must be recorded with velocity. |
| Velocity + temperature + humidity probe | Three-parameter remote monitoring | 0.01–25.0 m/s; 0–60°C; 5–95% RH | Use Model 0975-31 for combined environmental monitoring. |
Key Features
Fifteen compatible probes
Supports directional and omnidirectional probes for velocity-only, velocity-and-temperature, or velocity-temperature-humidity measurement.
Wide velocity coverage
Probe-dependent velocity ranges extend from 0.01 m/s to 25, 30 or 50 m/s for low-flow monitoring through higher-velocity process applications.
High-temperature capability
Selected probes support operating and compensation temperatures up to 100°C or 120°C for demanding equipment and process-air measurements.
Analogue and digital outputs
A DIP switch selects 4–20 mA current output or 0–5 V voltage output, while RS-485 supports digital communication.
Compact stationary design
The approximately 100 × 60 × 25 mm, 200 g main unit can be integrated into equipment or installed using the optional DIN-rail fixing base.
Remote multiparameter monitoring
Suitable probe configurations allow simultaneous output of air velocity, temperature and humidity for facilities, factories, data centres and IoT systems.
