Particulate Emission Monitoring
Solutions
for Foundry Processes
Knockout Sand Plant
On Knockout Sand Plant Filters where cooling water is often used, the
particulate carry over from the filter can be very moist (+25% relative
humidity). In these instances, PCME utilise their Patented Fully
Insulated Sensor to prevent short circuits that would occur with
standard metal probes. [top]
Bag Filters
Fume
To overcome the problems associated with monitoring the low levels of
dust normally associated with the high efficiency bag filters used in
foundry applications (typically single figure mg/m³), PCME’s systems
utilize a unique ElectroDynamic™ Probe Electrification
monitoring methodology incorporating a patented non-contact charge
transfer technique. This measurement technology is featured in a wide
range of dust monitoring systems accredited to international standards
(TUV and MCERTS) and designed to fully meet the exacting self-testing
and logging requirements (zero and span checks) required by
international regulations. [top]
Mould
& Core
Sensors are available with either a patented fully insulated probe or a
unique, AC based (ElectroDynamic™ Probe Electrification) rod.
This metal sensor is best used in the dry applications found in
foundries as it provides accurate, stable readings unlike the fully
insulated sensor, which can be affected by static charge build up when
used in dry conditions. Based on PCME’s wide experience of over 20,000,
applications insulated sensors are only recommended for damp/sticky
applications. [top]
Finishing
(Grinding And Shot Blast)
To provide the utmost confidence in the instrument’s performance,
PCME’s advanced monitoring systems incorporate not only zero and span
checks but also a unique patented secondary contamination ring, which
monitors any leakage currents or signals across the insulator thereby
proving the measurement integrity of the sensor. In many instances,
this eliminates the time consuming action required of industry to
physically inspect sensors to ensure functionality by fully automating
and logging probe contamination checks – a unique feature to PCME
instruments. [top]
