PRIMARY SAMPLERS
eDART’s wet process control primary sampler provides flexible installation options for both pressurized and unpressurized lines. Samples can be sent directly to an On-Stream Analyzer or to a poppet sampler for secondary sampling, ensuring accurate lab analysis with fixed-volume samples. Trusted by process control professionals, eDART’s sampler systems deliver reliable and precise results, enhancing confidence in operational accuracy.
PRESSURISED HORIZONTAL SAMPLER
The pressurized horizontal primary sampler efficiently collects flow from the central region of the main line for sampling purposes.
PRESSURISED VERTICAL SAMPLER
The pressurized vertical primary sampler collects samples from the centre of a pressurised line. In the first option, a "continuous sampling nozzle" is used to extract a sample stream. After secondary sampling, the remaining flow is returned to the sump. The second option enhances stream sampling by recirculating the flow within the primary sampler, enabling the secondary sampler to operate more efficiently.
GRAVITY VERTICAL DOWN SAMPLER
The gravity vertical down primary sampler ensures thorough mixing of flow, guaranteeing representative sampling in vertically down pipelines.
GRAVITY HORIZONTAL SAMPLER
The gravity horizontal primary sampler is designed for application in non-pressurized lines. It achieves this by intersecting the flow across the height of the stream. To enhance the sampler's size efficiency, the cutter can be bypassed using ports that pass directly through. These ports are designed to minimize turbulence around the cutter, optimizing sampler performance.
LITERATURE
SECONDARY SAMPLERS
eDART's wet secondary process control samplers are innovative adaptations of the well-established poppet sampler design. In a poppet sampler, a piston with durable seals is employed to enter the pressurized mainline. The piston pauses in its extended position to facilitate chamber filling before retracting to release the sample into a collection device at atmospheric pressure. These samplers excel in providing representative sampling over time, making them well-suited for process control applications.
POPPET SAMPLER
The original poppet sampler was introduced over three decades ago and has remained a consistent presence in minerals processing applications ever since. Recently, its design has been updated to enhance safety measures. This compact and cost-effective sampler is designed to extract a predetermined volume of slurry sample from the process line. Notably, the sample is delivered at atmospheric pressure, streamlining sample handling for added convenience.
THIEF SAMPLER
The thief poppet sampler is a specialized version of the poppet sampler that can be easily removed from the process line without requiring the shutdown of the line itself. This unique feature enables maintenance of the sampler outside of scheduled shutdown periods, contributing to operational efficiency. These samplers are widely utilized by eDART as primary process control tools, serving purposes such as control and calibration of densitometers, among other applications.
COARSE POPPET SAMPLER
The coarse poppet sampler is a specialized solution tailored for sampling coarse slurries, particularly in cyclone feed lines where particles of up to 15 mm in diameter are prevalent. Distinguished by a tungsten carbide piston plate and a wear-resistant polyurethane sampling chamber, this sampler prioritizes durability. Its primary applications include densitometer calibration and control purposes. Notably, the sampler is fully withdrawn from the process stream in the retracted position, a feature that contributes to prolonging its operational lifespan.
CORROSIVE LIQUID SAMPLER
The corrosive liquid sampler is a purpose-built solution designed to effectively sample corrosive liquids. This sampler is engineered to withstand the challenges posed by aggressive chemical environments, ensuring reliable performance even in the presence of corrosive substances. With a focus on durability and accurate representation, the corrosive liquid sampler provides a valuable tool for industries where handling corrosive liquids is a critical aspect of quality control and process monitoring.
VISCOUS LIQUID SAMPLER
The viscous liquid sampler is specifically crafted to tackle the unique demands of sampling high-viscosity liquids. Engineered to navigate the challenges posed by thick and sticky substances, this sampler ensures reliable and accurate sample collection even in the presence of viscous materials. Designed with a focus on precision and efficiency, the viscous liquid sampler is an indispensable tool for industries where dealing with thick liquids is essential for maintaining product quality and process control.
DRY POPPET SAMPLER
The dry poppet sampler is purposefully designed to effectively sample dry bulk materials. Engineered with precision, this sampler excels in capturing representative samples of solid materials such as powders and granules. Its specialized mechanism ensures reliable and accurate sample collection, making it a valuable asset for industries where obtaining consistent and representative samples of dry materials is crucial for quality assurance and process optimization.
