Multifunctional Industrial Transmitter for Humidity / Temperature / Dew Point / Absolute Humidity... The precise and reliable measurement of humidity in industrial processes is gaining more and more importance. The multifunctional transmitters series EE31 offer the ideal solution. The result of many years of experience in humidity measurement technology for industrial applications, the EE31 series builds on the E+E highquality HC series capacitive humidity sensor elements. The optimal hardware structure for varying applications is achieved by combining various standard mechanical and electronic modules. User friendly MS Windows software tools simplify the configuration of the transmitter, the data recording, visualization and processing. The measured values are available on two freely configurable and scalable analogue outputs and on the serial RS232 interface. With an optional RS485 module up to 32 transmitters can be connected to a network and one single PC interface allowing easy remote monitoring. Two freely configurable optional alarm outputs can be set by software. The measured data and the corresponding MIN/MAX values can be viewed on the optional LC display. Other features especially tailored for harsh industrial applications are the new housing concept consisting of three modules, the easy on-site adjustment and calibration, and the pluggable sensor option. These features allow for very fast and easy servicing of the transmitter. By selecting a suitable housing version the EE31 series can be used for the entire range of humidity measurement applications: - Model A for wall mounting - Model B for duct mounting - Model D with remote sensing probe for measurements in the extended temperature range -40...180°C - Model E with remote sensing probe for pressure tight applications between 0.01...20 bar (0.15...300psi). Network with up to 32 transmitters Up to 32 transmitters can be connected in a RS-485 bus system to a single PC interface. The measured and calculated data is stored in a PC database which is available for further processing. The data base can also be stored in ASCII format or in a database with ODBC interface. Product Configuration Software (EE-PCS) The Configuration Software is used for: - flexible, easy and fast setup of the analogue and alarm outputs. - adjustment of the humidity and temperature outputs. - exchange of the sensing probe or of the sensors. v1.7 / Modification rights reserved

Easy calibration and adjustment of the transmitter The modular housing of the EE31 enables a fast and easy on-site adjustment and calibration. Using the optional extension cable one can adjust or calibrate the entire measurement loop without interrupting the measurement. No need for time-consuming dismounting and wiring of the instrument. This feature makes the EE31 series suitable for use in regulatory environments (e.g. FDA, GAMP). The adjustment of humidity and temperature (2 points or 1 point) is performed either with a simple routine using two push buttons on the printed circuit board or...
