HD29 series Air speed, temperature and relative humidity transmitters
Air and Wind Speed
Accurate and versatile air velocity transmitters for precise environmental control. Measure air speed, temperature, and humidity with analog or RS485 Modbus output options.
The HD29 series ensures precise and reliable measurement of air velocity, temperature, and relative humidity for HVAC, clean rooms, industrial plants, laboratories, and environmental monitoring.
Equipped with advanced sensors and stainless-steel probes, these transmitters guarantee long-term stability and durability even in harsh conditions.
Key Features
Key Features:
- Measures air velocity from 05 to 20 m/s, temperature -10…+60°C, and RH 0-100%.
- High-precision electronics and factory calibration ensure accuracy right out of the box.
- AISI 304 stainless steel probe with wire mesh filter for protection and long life.
- Fixed or cable probe versions (2, 5 or 10m) for flexible installation.
- Configurable outputs: 4… 20mA, 0…10 V or RS485 (Modbus-RTU/ASCII).
- Fast or slow response mode for stable readings in turbulent airflows.
Applications
Ideal for HVAC systems, BEMS, pharmaceutical clean rooms, museums, industrial facilities and agricultural environments where accurate airflow monitoring is essential.
