The exact monitoring of dew point temperature in compressed air systems, dryers for plastic and other industrial processes is becoming increasingly more important. EE 371 series with a measuring range -80 60C Td (-112 140F Td) and EE 372 series with a measuring range -40 60C Td (-40 140F) are the ideal solution for such applications.
The core of the transmitter is the monolithic measurement cell type HMC01, developed by E+E Electronic 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 <2C Td (+-3.6F Td) possible.
The compact construction in a robust aluminium housing and the numerous options allow easy mounting and many application possibles.
Dew point temperature in the range of -60 -20C (-76 -4F) at room temperature correspond to relative humidity 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 autocalibration procedure is utilized to achieve high accuracy measurements at lowest dew points too.
Model T: The transmitter has two freely selectable and scaleable outputs for dew point, frost point or ppm volume concentration.
Model S: The switch with two relay outputs is designed for control and alarm purposes. The status for early warning and main alarm is indicated by LED's. Adjustment of the Td/Tf point and hysteresis can be achineved with the optional configuration software.
