  1. 1. Dräger Pulsar 7700/7900 Detection of flammable gases and vapour The Dräger Pulsar 7700/7900 is a stationary open-path gas detector for detecting potentially explosive hydrocarbons in gases and vapours. Its robust design and the extremely short response time of its sensor make the Dräger Pulsar 7700/7900 a reliable solution for challenges in the oil and gas and chemicals industries.

  2. 2. Benefits 02 | Dräger Pulsar 7700/7900 Reliable and fast measurement The Pulsar 7700/7900 detects a wide range of gaseous hydrocarbons, including methane, propane and also ethylene. An accumulation of these gases in critical concentrations can be measured at a distance of up to 200 metres within two seconds. This is achieved by the flashing frequency, which increases in strong mode. Status LEDs in the transmitter and receiver indicate even over a larger distance that the device is ready to operate. The Pulsar 7700/7900 also runs continual self-tests for additional safety and reliability. If the signal strength is insufficient, the transmitter sends out a freely configurable pre-warning signal. The system continues to detect gases whilst sending additional warning signal indicating that maintenance is required, for example because a lens has become dirty. This makes it possible to plan maintenance in advance and avoid unexpected downtimes. The Pulsar 7700/7900 is suitable for safety-related technical applications up to SIL 2. Reliable even in adverse weather conditions Reliability is not just ensured in ideal weather conditions. The Pulsar 7700/7900 uses strong mode to compensate for increased absorption of the signal intensity by fog, mist, heavy rain or snow. Lens heating also prevents the accumulation of snow and condensation on the lens. Easy alignment, configuration and commissioning It takes just one person to align the transmitter and receiver and then commission the system – the process is simple and does not require additional telescopic or alignment mirrors. Once the transmitter and receiver are roughly lined up by sight, a handheld terminal is used to achieve precise alignment. The terminal displays the alignment either in a coordinate system with crosshairs or as numerical coordinates. The integrated calibration function of the Pulsar 7700/7900 does not require manual adjustment or standard test gas. After the alignment procedure is finished a self-zeroing sequence is started to complete the commissioning of the system. The alignment and signal strength parameters are saved and then used later to detect any misalignments or accumulation on the lenses. On-site diagnostics The handheld terminal can be used for preventative maintenance and any fault diagnostics on site. In addition to support alignment and zeroing, the handheld terminal also has configuration and diagnostic functions. More comprehensive diagnostics are possible with the Dräger PolySoft PC software. Documented safety – integrated data logger and log report An integrated data logger saves the most recent errors, warnings and events. These include events such as beam blocks, gas alarms, warning signals and alignment and supply voltage problems. Alongside the data logger, there is also a summary log report that provides the values measured within an hour. The report contains important information, such as the measured gas value, signal strength and temperature. This data is available for the last ten weeks of operation. Information is also provided as a weekly summary from the last ten years of operation.
  3. 3. System Components Dräger Pulsar 7700/7900 | 03 D-6806-2016 Dräger REGARD® 7000 The Dräger REGARD® 7000 is a modular and therefore highly expandable analysis system for monitoring various gases and vapours. Suitable for gas warning systems with various levels of complexity and numbers of transmitters, the Dräger REGARD® 7000 also features exceptional reliability and efficiency. An additional benefit is the backward compatibility with the REGARD®. D-27777-2009 Dräger REGARD® 3900 The Dräger REGARD® 3900 is a standalone, self contained control system for the detection of Toxic, Oxygen and Ex hazards. The control system is fully configurable between 1 and 16 channels, depending upon the type and quantity of input/output boards installed. Accessories Weather guard Weather guard protects the system from adverse weather conditions, such as snow and rain. It is made of stainless steel 316 (including for each Pulsar 7700/7900 transmitter and receiver).
  4. 4. Accessories 04 | Dräger Pulsar 7700/7900 PIA – Pulsar interface adapter The Dräger Pulsar interface adapter (PIA) is robust, weatherproof and certified for hazard zones. The PIA provides two interfaces for communication with the Pulsar 7700/7900 through its intrinsically safe connection. Combined with a HART® handheld terminal or PC with PolySoft, it acts as a protocol converter via the IR interface to align and calibrate Pulsar transmitters and receivers. It also has configuration/ diagnostic options. ST-977-2001 Handheld terminal The handheld terminal from Dräger is a robust, weatherproof device approved for use in potentially explosive atmospheres. The terminal is used to align and zero the Dräger Pulsar transmitter and receiver. It also offers basic configuration and diagnostic functions. ST-3531-2003 AI 500 and adapter cable The digital AI 500 interface is used to provide extensive diagnostic data when connected with the Dräger Polytron PC software and a PC in the non-potentially explosive zone. Up to four Pulsar systems can be connected via this interface.
