HD103T.0  Air speed transmitter with hotwire sensor. Probe with 5m cable. Speed 0…5m/s.
Output selectable by a jumper: 0…20mA, 4…20mA, 0…5V, 0…10V.
Power supply 24 Vac (230 Vac on request). Working temperature 0…80°C.

The devices HD103T.0 measures air speed
by using an all-directional hot-wire probe.
It is provided with three configurable analogue
outputs: 4…20mA, 0…20mA current output
and 0…10Vdc volt-age output.

The choice of output type is made by means
of the jumpers set on the card.
The sensor set on the top of the probe is very
delicate and must be protected with the
special frame provided with the instrument.

During transportation, the sensor is closed into a cylinder screwed on the end part of the probe:
during installation, unscrew this cylinder and screw the protection frame in its place.
The relation between output range (current and voltage) and input range is fixed: the output
minimum and maximum values are associated with the minimum and maximum
values of the input variables.
