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.
