3 Product Description
3.1 General
The EE072 is a robust probe for relative humidity and temperature measurement. Its IP65 rating and
the E+E proprietary protective sensor coating make it ideal for highest requirements. This is also
underlined by the wide humidity and temperature working ranges of 0...100 %RH and -40...80 °C.
The EE072 is typically implemented in demanding process and climate control applications like in
agriculture, life stock, food, pharma or clean rooms. A wide choice of filter caps allow for versatile
options in challenging industrial applications. Installation is simplified by various mounting options which
are supported by E+E accessories.
The EE072 is available with two different interface versions, either with CANopen/CAN or with Modbus
RTU over RS485. The M12x1 connector links the probe to the digital infrastructure.

4 Installation
4.1 Wall and Ceiling Mount
Best measurement performance is achieved when the entire probe is located inside the environment to
be monitored.
In such a case, the EE072 may be for instance fixed onto a wall with the mounting clip HA010211 (not
included in the scope of supply, see data sheet “Accessories”), or freely hang from the ceiling on the
connection cable.

4.3 Recommendations for accurate Humidity and Temperature
Measurement
■ In case the EE072 probe is not entirely located in the environment to be monitored, large
temperature differences along the probe will lead to temperature gradients. These will have an
influence on the accuracy. Therefore, it is of paramount importance to minimize the temperature
gradients. The biggest part of the probe shall be located in the target environment and the rest shall
be thermally well insulated.
■ For outdoor applications the EE072 shall be equipped with a radiation shield (HA010502) which
provides protection from rain, snow and ice. This also causes a natural ventilation which largely
prevents overheating of the probe in the sun and thus a distortion of the measured values.
■ For highest accuracy of the measured humidity and the calculated parameters (e.g. wet bulb
temperature, dew point and others), the user can set the barometric pressure at the operating point,
using the EE-PCS Product Configuration Software (see „7.5 Configuration Interface“), via Modbus
protocol (see „5.1 Modbus Setup“) or via CANopen protocol. The factory setting is 1013.25 mbar.
■ Best accuracy is achieved with a velocity of min. 0.2 m/s of the air surrounding the probe. Depending
on the installation position, flow direction and flow velocity, the accuracy may decline. The following
table gives a concise overview. Please note that the vertical positioning with the sensing element
upside is the most sensitive one concerning accuracy. Because of possible self heating due to the
sensor electronics, it is crucial to have the indicated air flow velocity.

In a dusty or polluted environment it might be necessary to replace the filter cap once in a while. In most
of the cases, a clogged filter shows visible contamination or dirt. Longer response time of the humidity
measurement also indicates a clogged filter cap. In such cases, replace the filter by a new, original one,
see „7.7 Spare Parts“.
Procedure
■ Turn the filter cap counter-clockwise for removing it.
■ Install the new filter cap finger tight by turning it clockwise.
While replacing the filter cap take very good care to not touch or rub the sensing element.

7.3 Protection during Site Cleaning Operations
During site cleaning or sterilization process, if the EE072 remains on the measuring site the sensing
head can be protected with the optional protection cap for 12 mm (0.47") probe (HA010783, see
datasheet “Accessories”).
In case the probe is removed from the site, it is recommended to apply the protection cap for the M12
cable socket (HA010781) and the one for the EE072 M12 plug of (HA010782).
