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.

3.3 Electrical Connection

The relations of electrical potential between a bus system and an EE072 humidity/temperature sensor

are characterized by the following properties:

■ The bus connection is not electrically isolated from the supply connection

■ The individual EE072 node is not electrically isolated from the supply voltage

■ Each EE072 humidity/temperature sensor can be supplied separately

Tab. 2 Connection to the EE072 CANopen version, in accordance with CiA-303-1

In order to ensure a stable CANopen communication, the supply voltage must exceed the lower supply

voltage limit of 10 V DC within two seconds after power-on.

The EE072 triggers an alarm message if the supply voltage is outside the supply limits. The lowest

detectable voltage is 9 V and the highest 35 V.

3.4 Specification of the CAN Lines

The cables used for connecting the CAN bus nodes must comply with ISO 11898. Therefore, the lines

must have the following characteristics:

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.

4.2 Duct Mount

The probe also can be installed into a duct using the plastic flange HA010202 or the stainless steel

flange HA010201 (not included in the scope of supply, see data sheet “Accessories”).

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.

1. EE-PCS, Product Configuration Software and the Modbus configuration adapter HA011018.

The EE-PCS can be downloaded free of charge from www.epluse.com/configurator

2. Modbus protocol in the register 60001 (0x00) and 60002 (0x01).

See Application Note Modbus AN0103 (available on www.epluse.com/EE072)

The serial number as ASCII-code is located at read register address 30001-30008 (16 bits per address).

The firmware version is located at register address 30009 (bit 15...8 = major release; bit 7...0 = minor

release). The sensor name is located at register address 30010.

Please note: When reading the serial number or the sensor name, it is always necessary to read all 8

registers, even if the desired information requires less.

Please note: For obtaining the correct floating point values, both registers have to be read within

the same reading cycle. The measured value can change between two Modbus requests, therefore

exponent and mantissa may get inconsistent.
