Product Information

Benefits

  • Digital function
    • The Dräger VarioGard 33x0 IR is connected with the controller via a digital VarioGard bus. This is how it is supplied with electricity and how it transmits its measuring results. You can easily control the entire VarioGard system via the VarioGard bus.
  • Easy operation
    • Operation is extremely easy. You can make all configurations comfortably from the controller using VarioGard software. You can configure and monitor four current limit values and four averages over time for each transmitter.
    • The alarms are optically and acoustically displayed on the transmitter and trans­mitted to the controller. A three-colour LED indicates the operating status of the transmitter. The calibration is controlled using a magnetic wand via contact points.
  • High reliability
    • The Dräger VarioGard 33x0 IR is equipped with an infrared optical DrägerSensor. This sensor measures the concentration of flamable gases and carbon dioxide in the ambient air. The measured values are transmitted digitally to the controller and displayed there. An alarm is triggered if the gas concentration exceeds one or more of the configured limit values.
  • Individually configurable
    • The VarioGard 33x0 IR is adaptable to your needs. This means that you have different gas libraries available depending upon the desired use:
    • For example, the 3300 IR Ex detects LPG for garages and CH4 for methane monitoring that does not require explosion protection.
    • The 3320 IR CO2 is used for the detection of carbon dioxide in the ambient air in breweries and wine cellars, for instance.
    • In addition, you can place the cable inlets on all four sides of the transmitter. The transmitter can be mounted vertically as well as horizontally.
