دتکتور گاز ضد انفجار برند Drager مدل Polytron 8200 CAT
(Drager Brand Explosion-proof Model Ploytron 8200 CAT)
Description
The Drager Polytron® ۸۲۰۰ CAT is an advanced explosion proof transmitter for the detection of flammable gases in the lower explosion limit (LEL). It uses a catalytic bead DragerSensor® Ex … DD, which will detect most flammable gases and vapors.
Besides a 3 wire 4 to 20 mA analog output with relays, it also offers Modbus and Fieldbus protocols making it compatible with most control systems.
Benefits
Fast and stable – the DragerSensor® Ex … DD
The latest generation type DD gas sensor is based on the proven catalytic bead principle. Innovative dual active
elements result in very good long-term zero stability. Dräger has raised the bar yet again for poison resistance.
The resulting long service life provides you with low ownership costs. Measuring performance has also been
improved. The innovative gas inlet allows the sensor to respond to gas within a matter of seconds.
Easy device management via digital communication
The Drager Polytron 8200 is equiped 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 common HART® communication system, the fieldbus interfaces PROFIBUS® PA, FOUNDATION fieldbus™ H1, and Modbus RTU are also available.
Same design, same operating principle
The Drager Polytron 8200 CAT belongs to 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 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 8200 is operated by means of a magnetic wand over contact surfaces.
Three relays for controlling external equipment
Upon request, the Dräger Polytron 8200 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.
Audio alarms, signal lights, or similar devices can thus be controlled locally without an additional cable between the transmitter and central controller.
Safe, robust housing for every application
Polytron 8200 features a Class I, Div. 1 rated explosion proof enclosure made from aluminum or stainless steel, making it suitable for a wide range of environmental conditions.
A protection type “e” version includes a convenient docking station which allows installation in hazardous atmospheres without running conduit (where approved).
Make the impossible possible with the remote sensor
An available remote sensor condulet housing allows the sensor to be installed up to 30 meters (100 feet) away from the Polytron transmitter.
The sensor splash guard with integrated tubing nipple permits one person to perform a full calibration of a remote mounted sensor from the transmitter.
Data logger
The Polytron 8200 has a data logger, which records measuring and event data from prior years.
