HD403TS and HD4V3TS Active Hotwire Air speed transmitters
The HD403TS series of hotwire air speed transmitters are used for measuring and controlling air
speed
in ventilation ducts, clean rooms, extractor fans, as well as monitoring air quality (IAQ), etc.

| Model | Description |
|---|---|
| HD403TS | Active Hotwire Air speed transmitters |
These transmitters are equipped with a hotwire sensor, in the directional or omnidirectional version.
The HD403TS series of transmitters have a 4 - 20mA output, while the HD4V3TS series have a
0
- 10Vdc output.
Two measuring ranges are available: 0.05 - 40m/s for S1 and S3 models with directional probe and
0.05 - 5.00m/s for S2 and S4 models with omnidirectional probe.
The transmitters are factory calibrated and no further adjustments are required.
