Dräger Polytron 7000 Gas Detector

Overview

The Dräger Polytron 7000 is a gas detector that can satisfy all toxic gas and oxygen measurement applications on a single platform, meeting compliance requirements as well as the high specification demands of customized solutions. Dräger developed the simple, structured operation concept of the Polytron 7000 in close collaboration with customers, with a large graphic display that shows status information via pictograms and plain text to guide the user through calibration and configuration.

As a trusted supplier of Dräger safety equipment, Seven Star LLC proudly offers the Polytron 7000 to oil and gas, petrochemical, and industrial safety applications across the Sultanate of Oman, Muscat, and the wider GCC. Its intrinsically safe design and electrochemical DrägerSensor compatibility make it a dependable platform for continuous toxic gas and oxygen monitoring.

Measurement Principle

The Polytron 7000 uses proven electrochemical DrägerSensors, specifically developed for year-round, permanent use in stationary gas detection systems, known for their long life and excellent measuring quality. The Polytron 7000 can measure over 100 different gases, with the built-in sensor data memory containing all relevant calibration information, allowing the use of pre-calibrated sensors so the transmitter can function as a virtually maintenance-free device.

Three different software dongles adjust the transmitter to specific application requirements: the sensor test dongle performs patented sensor tests to verify reliability and functionality; the sensor diagnostic dongle evaluates sensor stress and remaining life to plan maintenance and replacement cycles; and the data dongle implements datalogger and eventlogger functions, storing gas values and events such as faults and alarms for later download and evaluation with Dräger Polysoft software.

Engineering Design of the Polytron 7000

The Polytron 7000 features a compact, impact-resistant, glass fibre reinforced polyester (GFRP) enclosure guarded against dust and splashing to IP66/67 and NEMA 4 ratings, measuring 16.6 x 13.5 x 12.9cm and weighing 1.98 lbs. The transmitter operates from a 16.5 to 30VDC 2-wire power supply across an operating temperature range of -40°C to +65°C, with an M20 cable gland entry.

The Polytron 4-20mA signal can communicate with a control system using HART, LON, PROFIBUS, or FOUNDATION Fieldbus, with the modular design allowing subsequent retrofit onto any of these interfaces. A remote sensor adaptor permits mounting the sensor away from the transmitter, while an optional relay module (two gas alarm relays, one fault relay) allows standalone gas detection without a controller, and a pump module option enables sampling from difficult-to-reach areas—both not suitable for hazardous areas.

Key Features

The Polytron 7000 combines intelligent sensor technology with extensive modular flexibility. Core capabilities include:

• Detects over 100 different toxic gases and oxygen on a single transmitter platform.
• Intrinsically safe design, verified to SIL 2 (IEC 61508-2).
• Built-in sensor data memory supports plug-and-play, pre-calibrated sensors.
• 4-20mA, HART, LON, PROFIBUS, and FOUNDATION Fieldbus communication options.
• Optional remote sensor mounting away from the transmitter.
• Optional relay module and pump module for standalone or remote sampling applications.
• Large 34x62mm graphic display with icon and plain-text guidance.
• ATEX, IECEx, UL, and CSA hazardous area approvals.

Industrial Applications

The Polytron 7000 is well suited to oil and gas, petrochemical, chemical, and food and beverage facilities across Oman requiring reliable, continuous monitoring of toxic gases such as H2S, CO, NH3, Cl2, and oxygen. Its remote sensor and pump module options make it particularly valuable for monitoring difficult-to-access areas or ducted process streams while keeping the transmitter accessible in a safe, convenient location.

As a trusted supplier of Dräger safety equipment, Seven Star LLC supports refineries, chemical plants, and industrial facilities throughout the Sohar and Salalah economic zones and the broader GCC region with the Polytron 7000’s proven toxic gas and oxygen detection platform.

Why Choose Seven Star LLC for the Polytron 7000 Platform

The Polytron 7000’s modular sensor and communication-dongle architecture is powerful, but it also means the wrong sensor choice at order time (wrong target gas, wrong measuring range for the specific process concentration expected) leaves a facility with a transmitter that needs a field sensor swap before it can be commissioned. Seven Star LLC’s engineers review the target gas list and expected concentration ranges with the customer before ordering, confirming sensor type, communication protocol (HART, LON, PROFIBUS, or FOUNDATION Fieldbus), and remote-mount distance requirements against the actual installation layout. We also help plan pre-calibrated spare sensor stock so a depleted sensor can be swapped without waiting on a fresh calibration cycle, and coordinate delivery across Oman’s refining and petrochemical sector around planned shutdown windows.
