Product advantages
Product highlights
Various models
The transmitter is available in three models: a standard configuration keyboard and an LC display; No keyboard and monitor type, connected to fixed installation display equipment; Equipped with a connector to connect to the handheld terminal. This makes it easy to maintain and calibrate even in hard-to-reach locations.
Full explosion-proof protection
The transmitter Polytron Ex is labeled II 2 G and complies with Directive 94/9/EG (ATEX 95) and is therefore available for Zone 1 and Zone 2. Polytron IR Ex is certified for worldwide use and meets IEC standards.
Intrinsically safe type
Dräger does not design a fireproof enclosure. This makes it lightweight, easy to maintain and install. Transmitter components such as sensors, LC displays, and - even remote controls - user keypads are intrinsically safe; No additional safety protection is required.
Technical parameters
The impact-resistant transmitter housing is made of conductive, fiberglass-reinforced polyester. The transmitter Polytron IR Ex is used in conjunction with a matched 4 to 20 mA central controller for optimal functional safety and system practicability.
