  • Page 7: System Description

    System description System description Task and fields of use HYGROPHIL ® H 4230 is a measuring system for determining the amount of Task water vapour in air and other gases. In many processes, monitoring and controlling gas humidity is a must if you want to achieve a consistently high product quality, use energy efficiently and adhere to the regulations regarding emission limits.

  • Page 8: Measurement Principle

    System description Measurement principle HYGROPHIL H 4230 works in accordance with the principle of psychromet- ® ric gas humidity measurement, measuring the difference in temperature be- tween two measurement sensors. The difference in temperature results from the fact that one of the two temperature sensors is moistened. Heat is re- moved from it by means of evaporation.

  • Page 10: Measuring Chamber

    System description 1.3.1 Measuring chamber Measuring chamber Water sensor Tube pump Ejector Pressure control module The venturi system and the water cylinder with the humidity sensors are ac- commodated in the measuring chamber. To begin with, the air to be measured flows through a venturi nozzle, in which the gas flow rate is determined by measuring the difference in pres- sure.

  • Page 11: Ejector

    System description With the specification HYGROPHIL H 4230-12 can the measuring gas be ® conveyed into the measuring chamber by using the present over-pressure. For this purpose a heatable pressure-reduction controller is to install before the gas sampling hose (see section 1.3.3). 1.3.2 Ejector The lower section of the measuring chamber contains the ejector, an air jet...

  • Page 47: Pressure-Reduction Controller

    Installation If you have installed HYGOPHIL properly, you can start up the equipment as described in section 4.1. Please note the following points with regard to set- ting the operating pressure:  Set the pressure at the compressed air conditioner’s reducing valve to a minimum of 2 bar to begin with and start measuring.

  • Page 48: Settings

    Installation 3.6.2 Settings Configuration For operating with over-pressure you must deactivate ejector operating.  Start programming mode (see section 5.1.2).  Open the menu EQUIP. CONF. (see section 5.2.4).  Open the submenu FLOW-CONTR (see section 5.2.4.5) and switch off the compressed air control.
  • Page 49 Installation During the start sequence of the device you must readjust this value until the final operating parameters are achieved.  Plug the bypass-jumper that deactivates the SILAS function.  Turn the switch S2 into position 9. This will deactivate monitoring of the pressure inside the enclosure and you can observe the display of HYGROPHIL H when the enclosure door is opened.

  • Page 50: Filling The Water Storage Tank

    Installation Filling the water storage tank In order to operate HYGROPHIL H 4230, you must pour demineralised wa- ® ter (extracted using the ion exchange procedure) or boiler feed water into the storage tank.

    PROFIBUS PROFIBUS HYGROPHIL H 4230 contains a certified PROFIBUS DP interface. All field bus-specific equipment data is listed in the GSD file „BARx077D.gsd“. The file is supplied with the product on a storage medium. The module specified there for I/O allows the user to request data by handshake. Framework structure The framework structure must comply with the following guidelines: Byte 0...

    PROFIBUS Bytes 4/5, offset high/low Input: The offset of a variable is to be taken from the channel description for the equipment (see section 8.3). Example: a read operation to data address 0x0020 with an offset of 0x0000 would deliver the dew point, whereas an offset of 0x0004 would address the measured value for the relative humidity (see channel description).
