EE240 Series

Wireless Sensor for

Humidity / Temperature / CO

State of the art sensor technology, highest reliability of data transmission and the ease of system installation are the outstanding features of the wireless sensor series EE240.

Wireless Transmitter EE245

The elegant housing combines the measurement of temperature, humidity and CO cation. As a standard, batteries provide for the power supply. For more power demanding applications the device can be powered through an external adapter.

Wireless Transmitter EE244

The industrial housing can be equipped with up to three sensing probes to contact the interchangeable probes. An optional display is available to provide local indication. As a standard, batteries provide for the power supply. For more power demanding applications the device can be powered through an external adapter.

Interchangeable Sensing probes

A modular structure and easy extendable assortment of sensing probes allow the usage in many applications. For many years, the proven sensor technology of E+E for the measurement values of humidity, temperature, and CO longtime stability. The standard interface and the stored calibration data of the sensing probe allow for any choice or combination of the available sensing probes offered. An adaptation or expansion of the number of sensing probes afterwards or an exchange for service purposes can be achieved in seconds – a must-have for uninterrupted data acquisition. For high temperature applications or installations in small spaces, the sensing probe can be connected with a sensor cable of up to 10 m

. An optional display is available to provide local indi-

guarantee precise measurements and the highest

(33 ft) in length.

Base Station EE242

The EE242 base station is the central component of a wireless network with up to 500 transmitters or up to 2000 measured parameters. With the base station and the integrated web server one can easily perform the setup of the entire wireless network. EE242 allows for easy remote access and diagnosis of the network. The measured data is available at the EE242 base station via Ethernet / Modbus TCP and RS485 / Modbus RTU. Four measured parameters can be selected to the analogue outputs (0 - 5 / 10 V or 4 - 20 mA). Measured data and status information are available also on the optional display.

Router Series EE244-R

The radio range is greatly depending on local circumstances. With the router series EE244-R obstacles can be bypassed or the transmission distance expanded.

Highest Transmission Reliability

The data transmission is based on the IEEE 802.15.4 protocol with a transmission frequency of 2.4 GHz, which can be used all over the world without any additional cost. A special identification address, checksums, handshakes, and bidirectional communication provide the highest transmission reliability. Typical radio ranges are 60 m

(197 ft) for indoor applications and 1000 m (3300 ft) in the open field. Greater radio ranges are easy

obtainable with routers. The self-configuring, scalable, and self-healing mesh network, even when a connection fails, is another component contributing to the improvement of the transmission reliability and security. The highest possible data security level is accomplished with a preset encryption key according to AES-128.

Parallel Operation

Parallel operation of several EE240 wireless networks (i.e. several base stations) is also possible. For this each transmitter and router may be within the transmission range of the routers and basis station of one network only.

Digital Bus Connection

For bus integration, Modbus is supported. Communication is implemented via Ethernet or RS485 interface.
