The EMS4 utilizes AC Coupled Triboelectric technology. As particles travel through the process they develop a charge. This charge is transferred as the particle passes or impacts the sensing element. The resulting current is amplified, filtered, rectified and further filtered looking only at the AC component, giving a linear representation of the concentration or mass flow rate of the particles in the gas stream, depending on the chosen scale for calibration. The reason for measuring the AC component is that compared to the component the electronics are more sensitive as the AC signal is substantially less affected by influences such as amplifier noise and process parameters, which includes the build-up of process dust on the sensing rod. The EMS4 sensing head totally filters out any 50Hz or 60Hz frequencies related to main supply. The amplified signal is then sent via a 4 core screened data cable to the controller for further processing, display and output of signal to various devices such as data logger or PLC. This technology is widely recognised as an acceptable means of continuously monitoring particulate emissions.

 

The Goyen EMS6 applies state of the art AC Tribo Electric sensing technology to emission and particulate flow monitoring. Its unique network compatibility allows installation of up to 2 devices without the need for a propriety processing box between the actual sensor and the PC or PLC. This facilitates the monitoring of multiple baghouses more conveniently and at significant cost saving.

 

COA 2000 Stand Alone System The COA2000 is a fully-integrated oxygen analysis system. The COA2000 combines the measurement probe with the electronics, display and controls into a single unit. Features:  - Probe mounted display interface for local control  - Full control, calibration and diagnostics    information  - Simple, push-button user interface with LED    display  - Automatic fault detection plus modbus    communications *Also available in Remote Display Model  (COA 2010 and COA 2020)

 

CPA 1000 Dust and Opacity Monitor The Goyen CPA 1000 Continuous Opacity Monitoring System (COMS) measures opacity by shining a light beam through flue gases. An internal microprocessor calculates dust density and other parameters. The instrument comprises the following parts: The Transmissometer which contains all of the electronic and electro-optic components; the Local Control Unit where the terminations and operator controls are located; and the air purge system. An optional data display Control Room Unit is available. The air purge system can take several forms depending upon individual site requirements. Single and dual electronic blowers are available, as are compressed-air driven devices. Continuous purge air supply is essential to prevent dust and corrosive gases from affecting the optical system. Automatic fail-safe shutters can also be fitted for temporary protection in the event of a purge air failure. The entire system is designed for continuous operation on all weather conditions, with minimal maintenance.

 

The Goyen PGA3000 is a lightweight portable gas analyser designed specifically for industrial applications. Each monitor can have a variety of different gases with up to a total of nine gases.
