Bergmann Engineers is specialised in distance measurements at high temperatures. Our sensors work at temperatures up to 1,000 C. Our systems offer a long-term stability of 0.01 %. The measurement electronic is separated from the sensor. The distance from between sensor and object may be up to 20 m. These systems are used e.g. for level control of liquid metals, or survey of the cast front in mill trains. These systems also provide appropriate solutions for control of weld seams or annealing furnaces for reliable functioning even under adverse environmental conditions. At room temperature, the systems reach an accuracy in the sub-micro meter range. In order to provide a maximum performance we customize our systems to cover the requirements of our clients. The sensors are custom-built in our own machine shop.
