Abstract
An on-line sensor mount assembly for monitoring one or more physical properties of a particulate material that is free flowing in the ductwork of a processing installation. The sensor mount assembly includes a vertical housing with an upwardly open inlet opening and a uniform vertical sensing passage/chamber. An outlet opening is located at the lower end of the housing. A flow metering apparatus is installed at the lower end of the housing and includes a flow metering element positioned in blocking relationship between the sensing chamber and the outlet opening. Continuous operation of the flow metering element transports material from the sensing chamber through the outlet opening at a regulated rate. This assures that the sensing chamber is full and that there is a uniform flow of material past one or more sensor elements installed on the housing and positioned to monitor the particulate material passing through the sensing chamber. The housing is adapted for installation in new or pre-existing ductwork of a processing system.
