Model | Description |
---|---|
HD 2001 | Barometric pressure, temperature and humidity indicator |
HD 2001.1 | Active indicator and transmitter |
HD 2001.2 | Barometric pressure and hot-wire air speed indicator |
HD 2001.3 | Active indicator and transmitter |
In addition all the models are fitted with an open collector type low-activated configurable alarm output.
The HD2001.1 and HD2001.3 model have three configurable analog outputs:
4...20 mA or 0...20 mA
current output, or 0...10 Vdc or 2...10 Vdc voltage output.
The choice of output type is made by means of jumpers set on the board.
Wind speed measurement is
detected by the HD2001.2 model with a hot wire probe set on the upper part of the instrument.
The large display with dual indication on all models allows one of the process variables on the first line
and the temperature on the second line to be displayed.
