Highlights
The Dräger Polytron® 8700 IR is an advanced explosion proof transmitter for the detection of hydrocarbon gases in the lower explosion limit (LEL) and ppm. It uses a high performance infrared Dräger PIR 7000 sensor, which will quickly detect most common hydrocarbon gases. Besides a 3 wire 4 to 20 mA analog output with relays, it also offers HART®, Modbus, and Fieldbus making it compatible with most control systems.
Efficient, stable and robust – the Dräger PIR 7000
The Dräger PIR 7000 is efficient, stable and robust. With its stainless steel SS 316L enclosure and drift-free optics, the Dräger PIR 7000 is built to withstand the harshest industrial environments, offshore installations for example. The unique doub … More Information
le compensated 4 beam measuring system makes the sensor resistant to dust or dirt deposits on the optical surfaces, environmental or ageing effects and long term drift.Choose a target gas with the smart gas library
Polytron 8700 offers a gas library with up to 100 gases providing a high degree of application flexibility. Each of the listed gases can be picked from a menu and automatically cross-calibrated with a standard calibration gas such as methane or prop … More Information
ane. The measuring range can be freely adjusted between 0 – 350 ppm and 0 – 100 % LEL enabling a wide variety of applications. No need to consult the factory when applications change.Easy device management via digital communication
The Dräger Polytron 8700 is equipped with digital interfaces allowing for quick and easy remote interrogation of the transmitter’s state. Integration with existing asset management systems such as PactWare is possible via DTM. In addition to the comm … More Information
on HART® communication system, the fieldbus interfaces PROFIBUS PA, FOUNDATION Fieldbus H1, and Modbus RTU are also available.Same design, same operating principle
The Dräger Polytron 8700 is a member of the Polytron 8000 series. All transmitters in this series have the same design and user interface. This allows for uniform operation with reduced training and maintenance requirements. The large graphic backlit … More Information
display shows status information clearly and in an easy to use format. The measured gas concentration, selected gas type, and measuring unit are displayed during normal operation. Colored LEDs (green, yellow and red) provide additional alarm and status information. The Polytron 8700 is operated by means of a magnetic wand over contact surfaces.Three relays for controlling external equipment
Upon request, the Dräger Polytron 8700 can also be supplied with three integrated relays. This enables you to use it as an independent gas detection system with two arbitrarily adjustable concentration alarms and one fault alarm. Audible alarms, sign … More Information
al lights or similar devices can thus be controlled locally without an additional cable between the transmitter and central controller.Data logger
The Polytron 8700 has a 35000 entry data logger, which records measuring and event data from the past years. A graph function displays the history of the past 15 minutes on a time/concentration graph.
Safe, robust housing for every application
Polytron 8700 features a Class I, Div. 1 rated explosion proof enclosure made from aluminium or stainless steel, making it suitable for a wide range of environmental conditions. The included splash guard features a chimney effect that actively draws … More Information
