Drager Brand Explosion-proof Fixed Gas Detector Model Polytron 5700 IR

Description

The Dräger Polytron® ۵۷۰۰ IR is a cost effective explosion proof transmitter for the detection of flammable gases in the lower explosion limit (LEL).

It uses a high performance infrared Dräger PIR 7000 sensor, which will quickly detect most common hydrocarbon gases.

A 3 wire 4 to 20 mA analog output with relays makes it compatible with most control systems.

Benefits

Efficient, stable and robust – the Dräger PIR 7000

With its stainless steel 316L enclosure and drift free optics, the Dräger PIR 7000 is built for the harshest

industrial environments such as offshore installations.

The unique 4 beam signal stabilizing system makes the sensor resistant to dust or dirt deposits on the optical surfaces.

Environmental and aging effects are compensated ensuring long term, drift free operation.

The integrated gas library with up to 100 gases provides a high degree of application flexibility.

Each of the gases listed there can be picked from the menu and automatically cross-calibrated with a standard calibration gas such as methane or propane.

No need to consult the factory when applications change.

Same design, same operating principle

Polytron 5700 belongs to the Dräger Polytron 5000 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 backlit display shows status information clearly with quick access to functions using a non-intrusive magnetic wand.

The gas concentration and measurement unit are displayed during normal operation.

Colored LEDs (green, yellow and red) provide additional alarm and status information.

Three relays for controlling external equipment

Upon request, the Dräger Polytron 5700 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 5700 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 PIR sensor to be installed up to 30 meters (100 feet) away from the Polytron transmitter.

A special calibration flow cell accessory permits one person to perform a full calibration of a remote mounted sensor from the transmitter.
