DescriptionThe HD 2011T... and HD 2012T... are microprocessor-controlled active humidity and humidity-temperature transmitters. The temperature range is configurable.These transmitters convert the humidity and temperature values into two linear current or voltage signals. Linearisation, with a digital technique, allows excellent precision and stability to be obtained. Each output of the transmitter may be selected between 0...20mA, 4...20mA or 0...10V and is set by means of a jumper.The absence of trimmers, potentiometers, etc. makes instrument calibration very simple: all that is required is to press a key while a led indicates any abnormal situations. The humidity input can be recalibrated using two saturated solution: the first with 75%R.H., the second with 33%R.H. The relative humidity range 0%R.H...100%R.H. is fixed: depending on the solution used, the value 0%R.H. corresponds to 0mA, 4mA or 0V, while 100%R.H. corresponds to 20mA, 1V or 10V. In the HD 2012 model, the user can set the temperature output in any range in the field -50...+200°C as long as the minimum amplitude is at least 25°C; a led indicates any alarm situations (temperature outside the set range, temperature sensor broken or short circuiting) and assists the user in the programming phase.Important note: the relative humidity sensor can work in the temperature range -40...+150°C. Beyond this range the transmitter can work till +180°C for brief periods or in a special execution
