Benefits

Exceptional signal stability

​Based on patented innovations, the Dräger PIR 7200 combines
maximum light-efficient optics with a signal-stabilizing 4 beam
technology. The double-compensating construction is characterized by the
greatest possible robustness towards interferences (e.g. dust and dirt
deposits). Due to its non-imaging nature, the measuring signal of the
Dräger PIR 7200 remains unaffected by a partially covered beam. It can
thus be ensured that the instrument fully complies with the requirement
“no false alarms”.

Maximum reliability – SIL 2 certified!

The Dräger PIR 7000 was developed and produced in accordance with SIL standards EN 61508 and EN 50402. For the first time ever, the software of a gas detection device was also assessed – excellent parameters and a SIL 2 certificate from the German TÜV certify the high product quality and reliability of the Dräger PIR 7000: Only two percent
of a SIL 2 budget are utilized by the Dräger PIR 7000. Therefore, there is still much flexibility in the selection of control system and actuators. The Dräger PIR 7000 therefore not only meets the SIL 2
requirements but far surpasses them.

Multiple configuration capabilities

​The standard parameterization of the Dräger PIR 7200 is based
on many years of experience. Nonetheless, the device provides the option
of setting many parameters specifically for customers and applications.
A smaller or bigger measuring range as well as configurable special
signals (for fault, beam block warning and maintenance) provide a wide
area of utilization.

​Fast response mode

The sooner a measurable gas concentration is indicated, the faster counter measures can be initiated. The configurable response mode of the Dräger PIR 7200 can be set to “fast” for this purpose. In this mode, each measurable gas concentration
is indicated within one second. In conjunction with low alarm thresholds, the gas transmitter can contribute to significantly reducing reaction times in the case of an emergency.

Olağanüstü sinyal kararlılığı

​Patentli yenilikler dayanarak , PIR 7200 Dräger sinyal stabilize 4 ışın teknolojisi ile maksimum ışık verimli optik birleştirir. Çift telafi inşaat etkileşimler (örneğin toz ve kirler ) doğru mümkün olan en sağlamlığı ile karakterizedir. Sayesinde olmayan görüntüleme doğaya , Dräger PIR 7200 ölçüm sinyali kısmen kapalı ışın tarafından etkilenmez. Bu nedenle cihaz tamamen ” hiçbir yanlış alarm ” şartı ile uyumludur sağlanabilir .

Maksimum güvenilirlik – SIL 2 sertifikalı !

Dräger PIR 7000 geliştirilen ve SIL standartları EN 61508 ve şimdiye kadar ilk defa EN 50402. uygun olarak üretilen bir gaz algılama cihazı yazılımı da değerlendirildi edildi – mükemmel parametreler ve Alman TÜV bir SIL 2 sertifikası yüksek tasdik ürün kalitesi ve Dräger PIR 7000 güvenirliği : Dräger PIR 7000 tarafından kullanılan bir SIL 2 bütçesinin sadece yüzde iki nedenle , halen kontrol sistemi ve aktüatörler seçiminde çok esneklik var. Dräger PIR 7000 , bu nedenle SIL 2 gereksinimlerini karşılar sadece ama çok onları aşar.

Çoklu yapılandırma yetenekleri

Dräger PIR 7200 standart parametreleştirme tecrübesi uzun yıllara dayanmaktadır. Bununla birlikte, cihaz müşterileri ve uygulamaları için özel birçok parametre ayarlama seçeneği sunar . Bir küçük veya daha büyük ölçüm aralığı yanı sıra ( arıza , kiriş blok uyarı ve bakım ) yapılandırılabilir özel sinyaller kullanımı geniş bir alan sağlamak .
