Dräger PointGard 3200, Detection of flammable gases and vapours

The Dräger PointGard 3200 is a complete 1-channel gas detection system for measuring combustible gases or vapours in ambient air. In its robust yet compact housing with IP66
protection class, you have all the necessary alarm equipment needed.

The PointGard 3200 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 function of a controller and the necessary alarm equipment, such as flashing lights and horn. The AC versions of the PointGard 3200 can be operated with an optional mains plug at any standard power outlet. If the measuring location is not suitable for mounting the PointGard, you can also order the device without a 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.

Use the PointGard 3200 where gas concentrations need to be monitored locally. A typical application is the measurement of flammable gases and vapours in unventilated or closed rooms. For this, the PointGard 3200 is installed outside the room at the entrance and the sensor in the room to be monitored. This way, you are informed about the gas concentration before entering the room. If the set 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.

Inside the PointGard 3200, you will find the proven electronics of our Dräger Polytron 8200. Our DrägerSensor DQ, which is characterised by a long service life and long-term stability, is used for measurement. With this sensor, the PointGard 3200 is able to measure practically all flammable gases and vapours in a range of 0 - 100 % LEL (lower explosion limit). The catalytic bead DrägerSensor DQ enables continuous measurement under atmospheric conditions in a temperature range from -40 °C to +65 °C.

The PointGard 3200 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 to be made between safe and unsafe conditions, there are combinations in green (safe) and red (unsafe) or green (safe) and blue (unsafe). The integrated horn has a sound pressure of 85-100 dB. It has been selected for industrial use in noisy environments. You can reduce the volume for less noisy environments, for example in the laboratory.

The PointGard 3200 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.

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 lighting conditions. The colours are adjustable via a slide switch inside the device. Below the display there are three status LEDs in green (ready), yellow (error) and red (alarm). All settings on the PointGard 3200 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 Ex Works. They can also be adjusted at any time.

In addition to the integrated alarm means, the PointGard 3200 also has potential-free changeover relays. These enable additional automated switching measures. Relays are available for A1, A2 and faults. Moreover, an external switching contact, for example a fault contact of neighbouring machines, can be read in and thus the green light (safe status) on the PointGard 3200 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 the Dräger PolySoft software or other HART® HHT.
