- Sensor: IR Sensor
- Installation: Non-explosion proof
- Interface: Dräger VarioGard Bus
- IP class: IP65
- Special: -
The Dräger VarioGard 3300 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.
The VarioGard 3300 IR is equipped with an infrared optical DrägerSensor. This sensor measures the concentration of flammable gases 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.
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.
The VarioGard 3300 IR is adaptable to your needs. This means that you have different gas libraries available depending upon the desired use. It detects LPG for garages and CH4 for methane monitoring that does not require explosion protection. 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.
