Failsafe detection of hydrocarbons
Featuring the latest infrared technologythe Draeger Polytron Pulsar Open Path Gas Detector is able to detect hydrocarbon leaks within a line of sight of up to 200m.
Designed to provide failsafe detection of a wide range of hydrocarbonsthis robust unit has built-in directional guidance and can be both aligned and commissioned without the need for special training.
Explosion proof and suitable for the detection of the alkane seriesfrom methane to hexaneas well as propylenemethanolethanol and ethylenethe Polytron Pulsar is easy to use and can be commissioned by just one person.
The integral calibration requires no manual adjustment or standard test gas and the alignment and signal strength parameters can be logged and used to determine optimum operating conditions.
Carrying a Safety Integrity Level rating of 2 (SIL 2) and offering a response time of less than two secondsthe Polytron Pulsar is designed to ensure that all faults are detectedthereby providing failsafe protection.
A continuous signal between the receiver and transmitter allows the system to adapt to difficult environmental conditionsand high power xenon lampscombined with a sophisticated algorithm which varies their intensity and frequencymakes the unit immune to solar radiationstack flaresarc-welding and resonance effects from rotating machinery.
Impervious to the effects of fogmist and snow across the beamit also features heated optics to eliminate snow and icing and prevent condensation.
The internal data logger maintains a detailed record of the previous seven days of operationand consolidates records for the previous 32 weeks.
Digital communications between the field and the safe area can also be providedwithout the need for extra cable coresby the addition of HART.
Meeting ATEXIECEx ULCSA and GOST approvalsthe Polytron Pulsar can be supplied with a variety of operating distances from 4 to 60m30 to 120m or 100 to 200m and is designed for use in temperatures ranging from -40 to 60°C.
