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.
