Humidity Transmitters

Eurocon Instruments offers Humidity Transmitters, HD2007. HD 2007T and HD 2008T are microprocessor configurable humidity and humidity-temperature 4 - 20 mA transmitters. The temperature range is configurable. They convert humidity and temperature values into two linear current signals (2 wires) in the field 4 - 20 mA. In the humidity-temperature combined version, the two circuits and the related outputs are completely independent one from the other. The linearization based on digital technique grants best accuracy and stability. Programming is carried out very easily by pressing a button. No operation by means of jumpers, potentiometers, etc. is requested. The humidity input can be recalibrated using two saturated solutions: the first one at 75%, the second one at 33%; the 0%R.H - 100%R.H. relative humidity range is fixed and 4 mA correspond to 0%R.H., while 20 mA to 100%R.H. In HD 2008 model, the operator can configure 4 to 20 mA temperature output in any range going from -50 C up to +200 C with 25 C minimum amplitude. A LED indicates the alarm states (temperature exceeding set-point, sensor failure or short-circuit) and helps the operator when programming. The relative humidity sensor may work in a -40 to +150C temperature range. Beyond this range till +180C it can work for brief periods.
