E+E Compact Dew Point Temperature Transmitter

The exact monitoring of dew point temperature in compressed air systems, dryers for plastic and other industrial processes is becoming increasingly more important.EE371 series with a measuring range -80...60°C Td (-112...140°F Td) and EE372 series with a measuring range -40...60°C Td (-40...140°F Td) are the ideal solution for such applications.

The core of the transmitter is the monolithic measurement cell type HMC01, developed by E+E Elektronik in thin-film technology.An autocalibration procedure which is integrated in the device and years of experience in low humidity adjustment make an accuracy of <2°C Td (±3.6°F Td) possible.Dew point temperatures in the range of -60...-20°C (-76...-4°F) at room temperature correspond to relativehumidity values of 0.08...5.37% RH. The measurement of these low humidity values is not possible with conventional capacitive measurement methods. For the EE371/EE372 series a special autocalibrationprocedure is utilized to achieve high accuracy measurements at lowest dew points too.
