exact dew point monitoring is increasingly playing a more impor-tant role in many industrial applications, such as drying process-es, air pressure pipelines, etc. For these purposes the multifunc-tional 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 measure-ments in a measurement range of -60…60°c td (-76…140°f td), with a td measurement accuracy of ±2°c (±3.6°f).two freely configurable and scalable analogue outputs are available for the two measurement values (td, t).

an optional hygrostat output, which can be set by means of a potentiometer, provides an alarm signal in a simple way when a threshold of the permitted dew point is exceeded.an optional display for the measurement values and the associated min/max values allows a quick overview of the current situation.

autocalibration

dew points in the range of -60…-20°c (-76…-4°f) at room temperatures correspond to relative humidity values of 0.08…5.37% rh. The measurement of such low humidity values is not possible with conventional capacitive measurement methods. For the ee35 series, a special autocalibration process is used to compen-sate for the usual drift effects and thus to achieve high accuracy measurements also at -60°c td (-76°f td).

installation

in addition to the direct mounting of the dew point probe, a ball valve installation enables the mounting and removal of the probe without having to interrupt the running process.

alarm output

an optional alarm module with one relay output is available for control and alarm purposes. The setting of the td threshold can be easily done with the potentiometer on the printed circuit board.

integrated power supply

a power supply, integrated in the back module of the housing, can be ordered optionally (100…240v ac, 50/60hz; ordering code v01). The power supply v01 is available for both polycarbonate and metal housing and comes standard with two plugs for supply and outputs to allow an easy connection.
