What Seltek does

Seltek is a privately held Turkish industrial-automation manufacturer, headquartered in Çekmeköy, Istanbul, that designs and builds Quality Measurement and Control Systems (QCS) for continuous web product industries. Its core platform accommodates up to six scanning frames and twenty-four sensors, and combines non-contact measurement technologies — isotope sources (Kr-85, Pm-147, Sr-90, Am-241), X-ray (including a regulation-free 4.99 kV Soft X-Ray sensor), Near Infrared (NIR), microwave, laser, capacitive, and eddy current — to measure thickness, basis weight, moisture, ash content, color, and porosity in metals, paper, plastics, nonwoven, calendering, textiles, coating, converting, and imitation-leather production lines. The system integrates Beckhoff PLCs and industrial PCs with a Windows-based HMI written in C# on an MS SQL database, plus Machine Direction and Cross Direction control actuators for closed-loop profile control.

Seltek generates revenue primarily through one-time equipment sales of custom-configured QCS installations and associated installation and commissioning services, sold via direct enterprise field sales to flat-products manufacturers globally and increasingly through channel relationships with major automation integrators — most notably ABB, where it achieved accredited X-ray thickness gauge supplier status in 2024 and received a Cairo, Egypt aluminium mill order through ABB MENA. Its commercial motion is supplemented by industry trade show presence (Aluminium Düsseldorf), newsletter demand generation, and a partners-and-suppliers ecosystem spanning Beckhoff, Microsoft, Schneider Electric, Comaintel, Phoenix Contact, Advantech, Dell, Festo, SMC, and Sew Eurodrive. Seltek reports no public revenue, no outside funding rounds, no disclosed patents, no management-team roster, and no certifications, leaving ownership structure and financial scale as data gaps.

Core offering

Seltek designs, manufactures, installs, and commissions process measurement and control systems (QCS) for continuous web product industries. The company offers custom-configured systems using isotope sources and X-ray sensors for non-contact measurement of thickness, basis weight, moisture, ash content, color, and porosity across aluminium, steel, paper, plastics, nonwoven, textile, coating, converting, calendering, and imitation leather manufacturing.

Product overview

Seltek offers a unified Quality Measurement and Control Systems (QCS) platform designed for continuous web product industries. The core system accommodates up to 6 scanning frames and 24 sensors, supporting multiple scanner types (O-Frame, C-Frame, Single-Sided, Single Point) and diverse sensor technologies including basis weight sensors (radioactive sources, X-ray, NIR), moisture sensors (NIR, microwave, RF), ash sensors (X-ray), caliper/thickness sensors (contact and non-contact), color sensors, and porosity sensors. Industry-specific solutions span aluminium, steel, coating lines, paper, plastics, nonwoven, calendering, textiles, converting, and imitation leather sectors. Cross Direction (CD) and Machine Direction controls are available for process automation, including gap control, extruder speed control, line speed control, and Automatic Profile Control (APC).
