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 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.

Mould & Core
Sensors are available with either a patented fully insulated probe or a unique, AC based (Electrodynamic) 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.
