About DELTA

DELTA SAS is a French manufacturer of sensors and measurement systems for the steel industry. The portfolio includes hot metal detectors (HMD) with fiber optics such as the Stato probes Z56, Z66, Z50 and Iris Z6500, infrared loop scanners (Rota probe TS), optical light barriers (CMD, e.g. VFT1) with die-cast aluminum housings, high-temperature inductive proximity switches of the IH series, laser measurement sensors (Trilas TL, Dilas FT) as well as compact measurement systems such as the DigiScan XD500 for width measurement in the cold rolling mill. The products are designed for use under extreme conditions: high temperatures, steam, dust and confined installation situations; mechanical components are made, among other things, of stainless steel. The offering is complemented by repair service, spare parts and a test bench (Test Bench). The company states that it can look back on almost 70 years of experience in the steelworks environment. Headquarters and production are located in Entzheim near Strasbourg (France); via DELTA USA there is a sales location in Pittsburgh, PA. Target industries are continuous casting plants, hot rolling mills (Long & Flat) as well as cold rolling mills and process lines.
