Sensor window contamination

It is important to keep the sensor window clean and checks should be carried out at

regular intervals–determined locally according to the type and degree of contamination

encountered– to ensure optimal performance of the ﬂ ame detector.

It is recommended that the ﬂ ame detector be disabled when the window is being

cleaned.

Applications for Marine UV Flame Detectors

Flame detectors are used when detection is required to be unaffected by convection cur-

rents, draughts or wind; tolerant of fumes, vapours, responsive to a ﬂ ame up to 25m away

and fast reacting.

Typical applications examples are:

• engine room

• factory

• garage

• hospital

• printing

• warehouse

Applications and locations to avoid:

• outdoors

• open windows and doorways

• electric sparks, arcs and welding

• UV lamps

• radiation sources

• prolonged ambient temperatures above 60°C

• exposure to water and ice

• gathering of dust or oil ﬁ lms on sensor window

• ﬂ ood or spot lighting falling directly on UV optics

• obstructions to ﬁ eld of view
