Delta Ohm HD2001 [HD2001.1] Relative Humidity, Temperature, Barometric Pressure Indicator Transmitter, RS232C, RS485 and Open Collector Output

The devices of the HD2001 series…, according to the models, measure temperature,relative humidity, barometric pressure and air speed by hot-wire probes. All the models areprovided with RS232C or RS485 serial output and the management of more than one deviceconnected to a network. In addition, all the models are fitted with an open collector typelow-activated configurable alarm output.The HD2001.1 and HD2001.3 model have three configurable analog outputs: 4…20mA or0…20mA current output, or 0…10Vdc or 2…10Vdc voltage output. The choice of output typeis made by means of the jumpers set on the board.Wind speed measurement is detected by the HD2001.2 model with a hot-wire probe set onthe upper part of the instrument.The large display with dual indication on all models allows one of the process variables on thefirst line and the temperature on the second line, to be displayed.

Model HD2001.2
The HD2001.2 model is fitted with an omnidirectional hot-wire probe: the sensor set on thetop of the probe is very delicate and must be protected with the special frame provided withthe instrument. During transportation, the sensor is closed into a cylinder screwed on the endpart of the probe: during installation, unscrew this cylinder and screw the protection frame inits place.In order to measure the wind speed accurately, the instrument must be set at a certaindistance from the wall using the HD2001.2.30 pole.
