Particulates
Filter plant trend monitoring
Highly sensitive triboelectric sensors provide the raw signals and alarms to develop a historical and easily retrievable data record of calibrated dust concentration from multiple filter plant.
Trend monitoring
The FPT F6-TM-Trend Monitor forms part of the FPT Network Datahub range of particulate monitors. It is a rugged, industrialised solution for monitoring filter media performance, whether it be for regulatory, plant performance or maintenance purposes.
It is used in conjunction with the well-renowned FPT303 Particulate Monitoring Probes to produce a fully featured and yet cost-effective solution to monitoring particulate emissions from multiple sources in modern-day industrial processes.
Overview
The units are housed in IP65/NEMA4 steel enclosures and can be located at most convenient points throughout an industrial facility. The F6-TM is configurable, with each unit able to monitor up to 6 probes, delivering both analogue representation of the particulate emissions and also fault and alarm relay status signals. The units offer operators clear, local indication of particulate concentration and include an ‘auto-sense’ feature to ignore offline units.
Included in the basic package is the ability to calibrate the readings against reference method gravimetric calibrations for genuine quantitative particulate measurement. Optionally data can also be stored to an onboard solid state data storage system. Communication between the display unit and the monitoring probes is via the industry standard RS485 MODBUS
communications protocol which ensures reliable data collection with low-cost installation.
The FPT303 sensing heads utilise Triboelectric technology, comprising a duct/stack-mounted IP67 electronics housing with integral sensing element protruding into the duct. As particles travel through the process they develop a charge, which is transferred as the particle passes or impacts the sensing element. The resulting current is amplified, filtered, rectified and further filtered giving a linear representation of the concentration in the gas stream.
