Highlights
The Dräger PointGard 3100 is a complete 1-channel gas detection system for detecting toxic gases or oxygen in ambient air. The robust yet compact IP66 housing already contains all necessary alarm equipment.
All-in-one
The PointGard 3100 is the optimal solution for all those who need a gas detection system but who do not want to go through the hassle of assembling all the necessary components. It contains the detection function of a transmitter, the supervisory fun … More Information
ction of a controller and the necessary alarm equipment such as flashing lights and horn. The AC versions of the PointGard 3100 can be operated with the optional power cable at any standard power socket. If the measuring location is not suitable for mounting the PointGard, you can remove the integrated sensor and place it up to 30 m away using the appropriate remote accessories. Appropriate accessories are also available for use in ducts and ventilation shafts.Application
The PointGard 3100 is used where a gas concentration needs to be monitored locally. A typical application is the measurement of hazardous gases in unventilated or closed rooms. For this, the PointGard 3100 is installed outside the room at the entranc … More Information
e and the sensor in the room where the substance is monitored. This way you are informed about the gas concentration before entering the room. If the alarm limits are exceeded, the PointGard warns with the integrated alarm devices. It can also trigger automatic ventilation so that the concentration is lowered and the room can be entered again without danger. In case of oxygen monitoring, ventilation would continue until a sufficiently high concentration is present again.Sensor Technology
Inside the PointGard 3100, the proven electronics of the Dräger Polytron 8100 are used. Both hardware and software have been evaluated by TÜV (Nord) and have proven SIL2 capability. The electrochemical DrägerSensor is used for the measurement. It is … More Information
characterized by long service life and long-term stability. With the various sensors that can be used in the PointGard 3100, more than 100 toxic gases can be measured. The DrägerSensors allow continuous measurement even under the most difficult conditions. Most DrägerSensors support a wide temperature range from -40 °C to +65 °C.Integrated Alarms
The PointGard 3100 already includes visual and audible alarms. The bright and long-lasting flashing lights warn of danger from a distance in orange (pre-alarm) and red (main alarm). If a distinction is made between safe and unsafe conditions, there a … More Information
re combinations in green (safe) and red (unsafe) or green (safe) and blue (unsafe).The integrated horn has a sound pressure of 85-105 dB. The horn volume can be adjusted to suit either industrial or laboratory applications. The side mounted horn silence button can be set to reactivate the horn in 3 minutes, 6 minutes, or permanent off until the next gas alarm.Power Supply
The PointGard 3100 contains a 120 ... 230 VAC/ 24 VDC power supply. It can optionally be ordered with a power cable and country-specific plug. If a local 24 VDC supply is already available, a variant without power supply unit is also available.
User Interface
The measured value, gas name and measuring unit are permanently shown on the display. If required, the concentration history of the last 15 minutes can also be shown. The display has a backlight in red or green to ensure readability even in poor ligh … More Information
ting conditions. The colors can be set via a slide switch inside the device. Below the display are three status LEDs in green (operational), yellow (error) and red (alarm). All settings on the PointGard 3100 are made via a password-protected menu. The three-button control allows quick navigation through the menu items. Measuring range and alarm thresholds are already set to the usual values after plugging the sensor. They can be adjusted at any time.Interfaces
In addition to the integrated alarm means, the PointGard 3100 also has dry contact switching relays. This enables additional automated switching measures. Relays are available for A1, A2 and faults. In addition, an external digital input, such as a f … More Information
ault contact of neighboring machines, can be read in and switch off the green light (safe status) on the PointGard 3100. For integration into higher-level systems (visualization systems, data acquisition systems, PLCs, central gas warning systems), the analog 4-20 mA current interface according to NE 43 can be used. HART® communication allows you to synchronize settings with a connected Dräger REGARD 3000 or Dräger REGARD 7000. In addition, remote access is possible via HART® using Dräger PolySoft software or other HART® communication devices.
