DELTA Sensors and Systems

What DELTA Sensors and Systems does

DELTA Sensors and Systems is a French privately-held manufacturer of opto-electronic sensors and measurement systems engineered for extreme steel mill environments. Founded in 1954 and headquartered in Entzheim near Strasbourg, the company has built a comprehensive product portfolio spanning Hot Metal Detectors (HMDs), infrared loop scanners, optical barriers, high-temperature proximity switches, laser measuring sensors (time-of-flight and triangulation), and stereoscopic measurement gauges, with operating capability up to 1,300°C. Core technologies include infrared scanning (Rota-Sonde), laser time-of-flight (Dilas FT), laser triangulation (Trilas TL), stereoscopic vision (DigiScan), and image processing (CropVision), all packaged in IP66-rated aluminum housings with military-specification components. Products integrate with customer automation systems via Profibus DP, Ethernet TCP/IP, and serial protocols, and some units are documented to have operated for 30+ years without failure. DELTA has been ISO 9001:2015 certified since 1995.

The company's revenue model is primarily capital equipment hardware sales supplemented by repair services and spare parts, priced EXW with no discount policy, 12-month warranties, and a 5%/month late-payment penalty. Distribution combines direct enterprise sales via the corporate website with regional subsidiaries in Germany (since 1972), the USA (1993), China (2004), and India (2007), complemented by a worldwide network of agents. The primary customer vertical is steel manufacturing, with use cases spanning continuous casting (bloom/billet and slab), hot rolling (long and flat), and cold rolling/processing lines. The company has expanded its technical scope through three bolt-on acquisitions: Polycaptil (2008, electronics/mechatronics), FCE (2011, electronics manufacturing), and OPALES (2013, industrial optical inspection and Cognex integration), giving the group in-house capabilities from sensors through machine vision integration.
