What Precision Samplers does

Precision Samplers, Inc. (PSI) is a privately held West Virginia-based manufacturer founded in 1979 that designs, manufactures, installs, and services heavy-duty custom mechanical sampling systems for bulk materials, with a primary focus on coal and petroleum coke. Its product portfolio spans three categories: (1) Auger Sampling Systems offered in Automated, Stationary, Modular Stationary, and Portable/Truck-Mounted configurations for sampling material from trucks, railcars, barges, and stockpiles — including a fully automated variant capable of weighing and sampling up to 600 trucks per day without operators; (2) Belt Sampling Systems comprising the Rotary Sweep Sampler and Conventional Cross Stream Sampler, integrated with 2-stage or 3-stage sample processing (crushers, secondary samplers, collectors, and reject handling); and (3) laboratory products such as the MSS-G3 Mechanical Sub Sampler. In 2019, PSI partnered with Sampling Associates International (SAI) to launch the patented Mechanical Part-stream Sampler (MPS), a stainless-steel conveyor-mounted device that performs Condition C Part-stream Cut sampling per ASTM D6609 and is customizable for any bulk material. All systems are designed to comply with ASTM D-7430 and ASTM D6609 standards.

PSI generates revenue across five streams: one-time equipment sales of custom-engineered mechanical sampling systems; turnkey installation services covering design, foundation, freight, mechanical and electrical installation, and commissioning; recurring Operation and Maintenance services (a model PSI pioneered in the late 1970s that has achieved documented availability exceeding 99%); system inspections and on-site repair services for both PSI and competitor equipment; and spare parts, including serial-number-specific inventory. The company operates a direct-to-enterprise go-to-market, selling to coal mines, preparation plants, export terminals, and bulk material handlers via in-house sales, relationships with major construction contractors, and a network of overseas agents spanning the United States, Canada, China, Taiwan, and South America. Over its 40+ year history, PSI has installed more than 300 systems across these geographies and maintains in-house project managers and field installation crews that enable single-source turnkey project delivery.

Core offering

Precision Samplers, Inc. (PSI) designs, manufactures, and installs custom heavy-duty automated mechanical sampling systems for bulk materials such as coal and petroleum coke. Product categories include auger sampling systems (automated, stationary, modular, truck-mounted, and trailer-mounted), belt sampling systems (Rotary Sweep and Conventional Cross Stream), 2-stage and 3-stage sample processing systems, the patented Mechanical Part-stream Sampler (MPS), and laboratory sample splitters. The company also provides turnkey installation, inspection, operation and maintenance, on-site repair, and spare parts services to its industrial customers.

Product overview

Precision Samplers, Inc. (PSI) is a manufacturer of heavy-duty custom mechanical sampling systems operating on a platform-plus-modules architecture. The core product portfolio includes three main system categories: (1) Auger Sampling Systems offered in four configurations (Automated, Stationary, Modular Stationary, and Portable/Truck Mounted) for sampling stationary bulk materials from trucks, railcars, barges, and stockpiles; (2) Belt Sampling Systems comprising Rotary Sweep Samplers and Conventional Cross Stream Samplers, each available with 2-Stage or 3-Stage sample processing capabilities for collecting representative samples from moving conveyors; and (3) Laboratory products including the MSS-G3 Mechanical Sub Sampler for coal sample splitting. PSI also recently launched the Mechanical Part-stream Sampler (MPS), developed in partnership with Sampling Associates International (SAI), for Part-stream Cut sampling from moving conveyors. Supporting these products are turnkey installation services and a suite of operational support modules including inspection, operation and maintenance, on-site repair, and spare parts services.

Direct peers

• Retsch (Verder Group): Manufacturer of laboratory mills, crushers, and sample-preparation equipment used downstream of bulk sampling. Directly comparable to PSI's MSS-G3 lab splitter and similar lab-side sample reduction workflows for coal and minerals.
• Gericke: Swiss specialist in bulk material handling and pneumatic/mechanical conveying equipment, including sampling systems. Comparable to PSI in custom-engineered heavy-duty equipment for bulk solids processors.
• Haver & Boecker: German family-owned manufacturer of screening, particle analysis, and sampling equipment for mining, minerals, and bulk materials. Directly comparable to PSI in providing custom-engineered mechanical sampling systems to coal and aggregate producers.
• Schenck Process: Industrial weighing, feeding, and sampling equipment manufacturer serving mining, cement, and bulk-material industries. Overlaps with PSI on conveyor-based sampling and feeder-integrated solutions for bulk solids handling.
• Gilson Company: US supplier of testing screens, sample splitters, and aggregate/coal sampling equipment. Closely comparable to PSI's lab and field sampling product line for the same construction materials and coal testing customers.
• Sampling Associates International (SAI): PSI's development partner for the patented MPS; a specialist in bulk-material sampling systems for coal and similar commodities. SAI competes directly with PSI in mechanical sampling design and serves many of the same coal export terminals and prep plants.

Broad incumbents

• Metso: Major global mining and aggregates equipment supplier offering crushing, screening, and sampling-related equipment. Operates broadly across mining flowsheets where PSI's sampling systems are deployed, but does not focus narrowly on mechanical sampling.
• Coperion: Global provider of compounding, extrusion, and bulk-material handling systems including sampling and feeding for industrial minerals and chemicals. Overlaps with PSI on engineered bulk solids handling equipment but serves a much wider process-industry footprint.
• FLSmidth: Global supplier of mineral processing, material handling, and sampling equipment to the mining and cement industries. A much larger incumbent whose sampling product line overlaps with PSI's coal/minerals focus but serves a much broader equipment portfolio.
• Thermo Fisher Scientific: Global life sciences and laboratory instrument conglomerate that supplies coal and mineral lab sample-preparation equipment. Comparable on the laboratory side of PSI's business (e.g., MSS-G3), though vastly broader in product scope and customer base.
