Product Description

Dewpoint Transmitter

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.

Autocalibration

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.

Outputs

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.
