EE22 Series
EE22 Series
Humidity / Temperature Transmitter
with interchangeable probes
Unique for the EE22 series are the interchangeable sensing
probes with connector.
The calibration data is stored in the probes, which are therefore
interchangeable and probe replacement does not affect the
performance of EE22.
The outstanding accuracy over the entire temperature range is
based on very precise calibration methods and on the latest
microprocessor technology. Well-proven E+E humidity sensor
elements ensure excellent long-term stability.
For high temperature applications (up to +80°C /
+176°F) or in case
of limited space availability, the sensing probes can be connected
to EE22 housing with cables (2m, 5m or 10m /
6.6ft, 16.4ft or 32.8ft)
without any repercussions for the overall accuracy of the
instrument.
Voltage 0 - 1 / 5 / 10V or current 4 - 20mA (2 wire)
outputs are available, of which the temperature output can be
scaled according to the application (see ordering guide).
EE22 is suitable for direct wall mounting and for installation on
rails according to DIN EN 50022.
The optional display indicates the actual RH and T values.

As useful accessories reference probes (incl. test report) representing
fixed humidity and temperature values are available.
They shall be installed instead of the measuring probes to check
function and accuracy of the evaluation unit.
One probe simulates high humidity and low temperature, the other
low humidity and high temperature, to check the upper and lower end
of both analogue outputs.
