EE220

v1.0

EE220 Series

Humidity / Temperature Transmitter

with interchangeable probes

Unique for the EE220 series are the interchangeable sensing

probes.

The calibration data is stored in the probes, therefore a probe

replacement does not affect the accuracy of EE220.

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 EE220 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 / 10V or current 4 - 20mA (2 wire) EE220-outputs

are available, of which the temperature output can be scaled

according to the application (see ordering guide).

EE220 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.

Duct mounting can be done easily with the optional

duct mounting kit.

Field calibration of humidity and temperature

In the pharmaceutical and biotechnology industry a Loop-

Calibration of the RH- and T-outputs, recommended by the

FDA (Food and Drug Administration), can easily be performed

utilizing separate RH- and T-probes (Type: EE220-xxx2x).

The RH- and T-outputs can be adjusted with push buttons on

the printed circuit board.

Reference probes

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.
