HUMIDITY TEMPERATURE PRESSURE AIRSPEED TRANSMITTERS 

HD2001 Temperature, relative humidity and barometric pressure indicator for use on the field.
Open collector alarm output and connection to PC through RS232C and RS485 serial port.
Software DeltaMet-8.
HD2001.1 Active indicator/transmitter for temperature, relative humidity and barometric pressure with selectable 0…20mA, 4…20mA, 0…10Vdc and 2…10Vdc outputs. Open collector alarm output and connection to PC through RS232C and RS485 serial port. Software DeltaMet-8.
HD2001.2 Temperature, relative humidity, barometric pressure and hot-wire air speed indicator for use on the field. Open collector alarm output and connection to PC through RS232C and RS485 serial port. Software DeltaMet-8.
HD 2001.3 Active indicator/transmitter for temperature, relative humidity with selectable
0…20mA, 4…20mA, 0…10Vdc and 2…10Vdc outputs. Open collector alarm output and
connection to PC through RS232C and RS485 serial port. Software DeltaMet-8.

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.
