Highlights
The Dräger PointGard 3100 is a complete 1-channel gas detection system for measuring toxic gases or oxygen in ambient air. In its robust yet compact housing with IP66 protection class, you have all the necessary alarm equipment needed.
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 measuring function of a transmitter, the assessment func … More information
tion 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 an optional power plug 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 corresponding remote accessories. In addition, appropriate accessories are also available for use in pipes and ventilation shafts.
The Application
Use the PointGard 3700 where gas concentrations need 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 entrance and … More information
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 you with its 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.The Measurement Technology
Inside the PointGard 3100, you will find the proven electronics of our Dräger Polytron 8100. Our electrochemical DrägerSensors are used for the measurement. They are characterised by a long service life and long-term stability. With the various senso … More information
rs 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.The Integrated Alarm Equipment
The PointGard 3100 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 are combi … More information
nations in green (safe) and red (unsafe) or green (safe) and blue (unsafe). The integrated horn has a sound pressure of 85-100 dB. It was selected for industrial use in noisy environments. You can reduce the volume for less noisy environments, for example in the laboratory.The Power Supply
The PointGard 3100 contains a 120 ... 230 VAC/ 24 VDC power supply. You can also order it with a power cable and country-specific plug as an option. If a local 24 VDC supply is already available, a variant without power supply unit is also available. … More information
The Operability
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 colours 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.The Interfaces
In addition to the integrated alarm means, the PointGard 3100 also has potential-free changeover relays. This enables additional automated switching measures. Relays are available for A1, A2 and faults. Moreover, an external switching contact, for ex … More information
ample a fault contact of neighbouring machines, can be read in and thus the green light (safe status) on the PointGard 3100 can be switched off. For integration into higher-level systems (visualisation 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 synchronise settings with a connected Dräger REGARD 3000 or Dräger REGARD 7000. Furthermore, remote access is possible via HART® using Dräger PolySoft software or other HART® HHT.
