- Model 4200 - Non-Compliance Dust Emissions Monitor

From

0

Simple, lightweight dust and opacity monitor designed to measure emission levels in combustion processes where regulatory compliance is not required (for sale in Asia only). The 4200 dust and opacity monitor is AMETEK Land’s compact, cost-effective solution for the continuous monitoring of dust, smoke and particulates in a wide range of industrial applications. NOTE: The 4200 is currently available only in Asia.

A lightweight design makes installation and positioning simple, even in challenging applications. The low-maintenance design has no moving parts – ensuring it operates reliably and continuously for immediate cost and performance benefits.

Using a single red LED to effectively monitor hot, dirty or toxic process conditions, 4200 requires only the installation of a transceiver and retro-reflector, fitted either side of the stack. The system alternates between measurement and flood sources to eliminate drift and ensure accuracy.

Ideally suited to multi-process plants with common exhaust stacks, the 4200 is designed for measurements in power generation, minerals, and industrial boilers.

Versatile Application Use
The 4200’s flexible and reliable measurement makes it ideal for use in a range of applications, including particulate removal systems, combustion efficiency monitoring and precipitator power optimisation.

Simple Keypad Control
Easy keypad operation allows straightforward access to the 4200’s functions. Setup, calibration, diagnostic and alarm settings can all be adjusted, providing optimum instrument performance for your process. Measurements can be displayed and output in % opacity or mg/m3.

Customise to Your Process Needs
Extensive accessories enable users to customise the 4200 to their precise process conditions. Options include air blower/mover systems and waterproof covers.

The Model 4200 is a compact smoke, dust and particulate monitor for measuring dust emission concentrations on industrial processes and non-compliance applications. This dust monitor is ideally suited to multiprocess plants with common exhaust stacks.

Simple installation, low maintenance and ease of operation ensure immediate results - vital where performance, cost and compliance benefits are of high priority.

The Model 4200 dust monitor forms part of the highly successful 4000 series range of dust, opacity, smoke and particulate monitoring systems.

Leading Technology:

The patented dual LED technology of the Model 4200 has proven itself worldwide as stable, reliable and trouble free. The  lightweight and compact design makes it ideal for a wide range of applications. Simple installation, low maintenance and ease of  operation ensure immediate results - vital where performance, cost and compliance benefits are of high priority.

Flexibility:

Particulate measurements are displayed in % opacity or mg/m3. Easy access is provided to all instrument functions, through a removable cover on the Transceiver. All Setup, Calibration, Diagnostics and Alarms settings can be adjusted - to ensure  optimum instrument performance.

The cross-stack, double-pass measuring system comprises a transceiver and retro-reflector unit. The transceiver has a high intensity source LED, which sends a beam of light through a diffuser and onto a beam splitter. Half of the light is transmitted via a lens to the retroreflector unit. The light returned is focused on to a measurement detector.

The remaining light reflected by the beam splitter is focused onto a reference detector. The opacity value is calculated from the ratio of the two detected signals.

The instrument alternates between the measurement and flood LEDs every second to eliminate drift and maintain accuracy.
