HD403T Active
Hotwire Air Speed Transmitters |
|
|
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.
|
 |
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. |
