Air Speed Transmitters HD 103T.0
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 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.
