Emission warning device for indicating pipeline rupture, has sensor for detecting abrasive material transported along pipeline within housing sealed around outside of pipeline section likely to rupture

摘要

The emission warning device has a housing (5) provided by 2 cooperating housing shells, which is sealed around a pipeline section likely to rupture, e.g. a 90 degree pipeline section (2), with a sensor within the housing for detecting the abrasive material transported along the pipeline (1). The sensor can be provided by a light barrier sensor (8,9), conductivity sensor, or a temperature sensor.
