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 HLX31 offer the ideal solution. The result of many years of experience in humidity measurement technology for industrial applications, the HLX31 series builds on the high-quality 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 scaleable analogue outputs and on the serial RS232 interface. With an optional RS485 module or Ethernet 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 HLX31 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 by using the data logging and analysis software. The data base can also be stored in ASCII format or in a database with ODBC interface. Ethernet interface HLX31 transmitters can be connected through a standard Ethernet-port for easy remote monitoring (ordering code E). The software-tools are in the standard scope of supply.

Software Tools Configuration Software (included in the scope of supply): 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. Datalogging and Analysis Software (optional): This user friendly software tool is a great help for easy data analysis in graphical or spreadsheet format on a PC as well as for data and alarms management by e-mail or SMS. Easy calibration and adjustment of the transmitter The modular housing of the HLX31 enables a...
