Delta Ohm HD103T.0 Air sSpeed and Temperature Transmitter

The HD103T.0 measures air speed by using an omnidirectional hotwire probe. It has three confi gurable analogue outputs: 4…20mA and 0…20mA current outputs and 0…10Vdc voltage output (0…1Vdc or 0…5Vdc outputs can be supplied on request). The output can be chosen by using the jumpers inside the instrument. 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 top of the probe; during installation, unscrew this cylinder and screw the protective cover in its place. 

Installation notes:

Select the type of air speed and temperature output by using the jumpers placed on the board. The probe must be used with clean air only and humidity below 80%. The transmitters are factory calibrated and no further adjustments are required. Each instrument is calibrated it own probe. Dont mix up probes and instruments: the calibration will have to be repeated.
