Sensor passes evaluation

Draeger Safety has passed a formal evaluation of its Polytron 7000 Oxygen and Toxic Gas Detector by the British Nuclear Industry Smart Instruments Working Group.

The evaluation included quality control and assurance, proven inuse data of the instrument and production methods for both the hardware and software elements of the transmitter.

The Draeger Polytron 7000, with selfdiagnostic functions, has been classified as suitable for use as a SIL 1 (Safety Integrity Level) instrument under IEC61508, electric electrical and programmable electronic equipment used in safety systems.

The range of electrochemical sensors incorporate “plug-andplay” technology. The sensor is plugged in and the detector is ready to use with no further intervention from the operator. The sensors offer a long life, with calibration intervals of up to one year to help further enhance the cost reducing benefits.
