An ER 060 series light emitter and receiver unit creates a light path across the internal diameter of a stack or duct for an Opsis emissions monitoring system.
Light is generated by a xenon lamp in the emitter and projected to the receiver.
From the receiver, it is passed to the analyzer through a fibre optic cable. Both the emitter and the receiver are mounted on external pipe flanges. The emitter uses an Opsis PS 150 power supply unit, which requires an electrical connection to mains. The interiors of the emitter and the receiver are protected by windows, which have connections for cleaning by compressed air. ER 060 for applications including one analyzer and ER 062 for applications including two analyzers.
