Particulate emission monitor

The Goyen EMP7 self-contained particulate emission monitor is accurate for most particle and particle characteristics and covers a wide range of dust concentrations, insertion temperatures, duct sizes and stack materials.

It continuously monitors particulate flow, primarily emissions from process plants. Each particle travelling through the process develops an electrical charge. As the particle passes or impacts with the sensing element, a current is induced which is processed in the monitor using a method called Impulse Signature Extraction (ISE). ISE technology extracts the basic characteristics (the 'signature') of the impulse signals induced by individual particles in the gas stream. Since these characteristics are related to such things as the particle velocity, the monitor is able to compute velocity as a parameter, and therefore to calculate the emission level as either mass flow rate or mass density, depending on the model selected.

It features wide, adjustment-free range of concentration and mass flow, and simple 4-20 mA, 2-wire output connection. Calibration is constant, it tolerates high leakage of signal due to insulator bridging and it offers seamless interface into industrial controls systems such as PLC.
