  • Page 7: System Description

    System description System description Task and fields of use Task ® HYGROPHIL H 4230 is a measuring system for determining the amount of 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 psychrometric gas humidity measurement, measuring the difference in temperature between two measurement sensors. The difference in temperature results from the fact that one of the two temperature sensors is moistened.

  • Page 10: Measuring Chamber

    System description 1.3.1 Measuring chamber The venturi system and the water cylinder with the humidity sensors are accommodated 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 pressure.

  • Page 11: Ejector

    System description 1.3.2 Ejector The lower section of the measuring chamber contains the ejector, an air jet pump that pumps the measurement air through the measuring chamber by means of compressed air. Negative pressure of up to -200 hPa is allowed at the extraction point.

Pull it to and fro through the opening. Upper measuring chamber section Extract the dry temperature sensor (detach the white knurled nut and carefully extract the sensor).
  • Page 88 Maintenance Attention: Be careful with the measuring cell. The ceramic ring in the measuring cell is brittle and can therefore be broken easily. Lower measuring chamber section with ejector You should not dismantle the ejector because it is adjusted at the factory in order to maximize efficiency.
  • Page 89 Maintenance ● Clean both parts of the ejector. Use a piece of cloth or brushes and a detergent that is able to dissolve the respective film of dirt. Attention: Never use sharp-edged objects to clean the ejector. The ejector gets waste if its surface is scratched.
