Depending on the models, the products of the HD2001 series can be utilized for relative humidity, barometric pressure, measuring temperature and air speed by hot-wire probes (HD2001.2).
Every model is supplied with RS485 or RS232C serial output and can control any device with a network connection. Additionally, each model incorporates an open collector type low-activated alarm output which can be configured.
There are three analog outputs which can be configured for the HD2001.1 and HD2001.3 models. These are 4 to 20mA, 0 to 20mA current output, 0 to 10Vdc or 2 to 10Vdc voltage output. The decision of which output type to use is decided by the jumpers set on the board. The HD2011.2 model detects the wind speed measurement using a hot-wire probe set located at the top of the instrument. It also boasts a wide display with dual indication so that both process variables and temperature are displayed on two lines.
