Exact dewpoint monitoring is playing an increasingly more important role in many industrial applications, such as drying processes, air pressure piplines, etc. For these purposes, the multifunctional EE35 Series offers the ideal features. The EE35 Series is based on a functional, user-friendly housing concept and on the proven polymer humidity sensors of the HC Series. A specially developed autocalibration process enables measurements in a measurement range of -60...+60 degC Td, with a Td measurement accuracy of ±2 degC. Two freely configurable and scaleable analogue outputs are available for the output of the two measurement values (Td, T). An optional hygrostat output, which can be set by means of a potentiometer, can provide an alarm signal in a simple way when a threshold of the permitted dewpoint is exceeded. An optional display for on site display of the measurement values and the associated MIN/MAX values allows a quick overview of the current situation.
