Dräger PointGard 3200

The Dräger PointGard 3200 is a complete 1-channel gas detection system for detecting combustible gases or vapors in ambient air. In the robust yet compact IP66 housing already contains all the necessary alarm equipment.

All-in-One

The PointGard ­3200 is the optimal solution for all those need a gas detection system but do not want to go through the hassle of assembling all the necessary components. It contains the detection function of a transmitter, the supervisory 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 the optional power cable at any standard power outlet. If the detection 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 with the corresponding remote accessories. Appropriate accessories are also available for use in pipes and ventilation shafts.

Application

The PointGard ­3200 is used where a gas concentration needs to be monitored locally. A typical application is the measurement of flammable gases and vapors 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 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.

Sensor Technology

Inside the PointGard ­3200, the proven electronics of the Dräger ­Polytron ­8200 are used. Both hardware and software have been evaluated by TÜV (Nord) and have proven SIL2 capability. The DrägerSensor DQ, which is characterized by 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.

Integrated Alarms

The PointGard ­3200 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 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. 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 ­3200 contains a 120 ... 230 VAC/ 24 VDC power supply. It can optionally be ordered with the power cable and country-specific plug. If a local 24 VDC supply is already available, a variant with a variable range DC-DC 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 lighting conditions. The colors 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.

Interfaces

In addition to the integrated alarm means, the PointGard ­3200 also has dry contact switching relays. These enable additional automated switching measures. Relays are available for A1, A2 and faults. In addition, a digital input (DI) such as a fault contact of neighboring machines, can be read in and switch off the green light (safe status) on the PointGard ­3200. 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 the Dräger PolySoft software or other HART® devices.
