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)
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.The compact construction in a robust aluminium housing
and the numerous options allow easy mounting and many application possibilities.
Autocalibration
Dew point temperatures in the range of -60...-20°C (-76...-4°F) 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 auto calibration
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 set point and hysteresis can
be achieved with the optional configuration software.
Configuration Software
The optional configuration software allows flexible and easy adjustment of the analogue resp. relay outputs
to the respective requirements.
The adjustment / calibration of the transmitters can easily be performed.
