Dräger Pulsar 7000 Series
The Pulsar 7000 Series detects a wide range of gaseous hydrocarbons. These include methane, propane and ethylene. An accumulation of these gases in critical concentration can be measured at a distance of up to 200 metres within two seconds. To do this, the system enters a specific mode with increased frequency. Status LEDs in the transmitter and receiver indicate the operational readiness of the respective device even over a greater distance. The continuous self-monitoring of the Pulsar 7000 series offers additional security. If the signal strength is insufficient, due to dirty optics or other non-operationally critical impairments, a configurable alarm signal will be issued to indicate the need for maintenance. However, the system remains ready for use and can continue to detect gases. In addition to increased operational readiness, there is the benefit of being able to plan maintenance and avoid unexpected downtime. The Pulsar 7000 Series is suitable for safety-related applications up to SIL 2.
With the Pulsar 7000, reliability is not at risk even when the weather is not ideal. For fog, mist, heavy rain or snow, the Pulsar 7000 Series has a mode with increased frame flash rate and light intensity. Thus, increased IR absorption caused by environmental factors is consented for. In addition, the heated optics prevent condensation or ice forming on the lens.
The alignment of the transmitter and receiver and the subsequent commissioning of the system can be easily done by a single person, without the need for an additional telescope or alignment mirror. After an initial rough alignment by eye, the exact alignment of transmitter and receiver is carried out using a handheld terminal. The alignment is displayed either in a coordinate system with target optics or in the form of numeric coordinates. The built-in calibration feature in the Pulsar 7000 Series does not require manual adjustment or test gas. After alignment, an automatic zero point adjustment starts, which completes the commissioning of the system. All parameters are stored and later used to detect misalignments or deposits on the lenses.
The handheld terminal can be used for predictive maintenance and on-the-spot troubleshooting. In addition to alignment and zeroing support, the handheld terminal also provides configuration and diagnostic features. Comprehensive diagnostics are possible with the PC software program Dräger PolySoft.
An integrated data logger stores the most recent errors, warnings and events. These include, for example, events such as blockages of the signal path, gas alarms, warning signals, or problems with the alignment or with the supply voltage. The data logger is supplemented by an hourly log of the values measured in this time. This includes essential data such as gas reading, signal strength and temperature, which are available for the last ten weeks of operation. Even after that, information is available as a weekly summary of the last ten years of operation.
The Pulsar 7000 Series offers suitable models for the most diverse applications. The offshore models are equipped with stainless steel junction boxes and cable glands. This makes them particularly robust and able to withstand the harsh environmental conditions. You can use the cross-duct model to detect gas buildup in supply or exhaust ducts. The system is specially designed for shaft installations.
