E+E EE220 Specifications
EE220
The innovative, modular EE220 humidity (RH) and temperature
(T) transmitter consists of a basic unit and various pluggable,
interchangeable probes.
The basic unit can accommodate one combined EE07 RH and T
probe or two separate EE07 probes, one for RH and one for T.
The EE07 probes are available in plastic or in stainless steel
enclosure and can be plugged onto the basic unit either directly
or with M12 extension cables up to 10 m (32.8 ft) long. An
optional kit facilitates the mounting of the probes in a duct.
The EE220 basic unit is available with polycarbonate or with
metal enclosure, suitable for wall mount or for installation on rails
(DIN EN 50022). For pharma and food industry the basic unit
features a rear cable inlet.
The measured values are available on two analogue voltage or
current (2 wire 4 – 20 mA) outputs, as well as on the optional
display.
One or two point adjustment for RH and T of the transmitter can
be easily performed with push buttons on the electronics board of
the EE220 basic unit. Alternatively, the EE07 probes can be
adjusted individually with the EE-PCA Product Configuration
Adapter (see EE07 data sheet).

For surface moisture monitoring or for the early detection of condensation danger, EE220 can accommodate
the EE03 RH & T module (see data sheet EE03).
Typical Applications Features
Pharma, biotech
Incubators and clean rooms
Cool chambers
Storage rooms
Outstanding accuracy and long term stability
Wide temperature working range
Interchangeable probes
Easy loop calibration
Field Loop Calibration
A loop calibration or adjustment in the field, as required by the FDA
(Food and Drugs Administration) regulated industries is easily
possible for the EE220 with two separate probes. Using extension
cables, the EE07 probes can be dropped into calibrators without
dismounting the EE220 basic unit.
The illustration shows the EE07 RH probe placed into the Humor 20
high end portable humidity calibrator and the EE07 T probe in a dry
block calibrator.

Reference Probes
A functional and accuracy check of the EE220 basic unit can be performed using
reference probes instead of the regular EE07 probes. These are certified by
individual test report and available for two pairs of fix RH and T values:
• RH = 10 % and T = 45 °C (113 °F)
• RH = 90 % and T =5 °C (41 °F)
Sensor Protection by E+E Proprietary Coating
The E+E proprietary sensor coating is a hygroscopic layer applied to the active surface of the RH sensing
element. The coating extends substantially the life-time and the measurement performance of the E+E sensor
in corrosive environment. Additionally, it improves the sensor’s long term stability in dusty, dirty or oily
applications by preventing stray impedances caused by deposits on the active sensor surface.
