Precise, Linear, Compact: LVDT Sensors from Schramme Set Industry Standards

Magnetbau Schramme is an international company that has been developing and producing solenoids, proportional valves and LVDT sensors since 1975. As a traditional and innovative family company, it has production sites in Germany and China. Most of the products are developed according to specific customer requirements. schramme attaches great importance to lean production and management processes and has therefore implemented the LEAN management philosophy in every department of the company. All products meet the highest quality standards and the company is certified according to ISO 9001 and IATF 16949.

In addition, the company's products cover a wide range of fields, including solenoids, valves, sensors, etc., and are used in a number of industries, such as automotive, machine building, food industry, medical technology, etc.

External Position Sensors LVDT

Schramme is a specialist in external position sensors (LVDT) or path receivers. The path sensors LVDTs developed by Magnetbau Schramme are distinguished by their extreme accuracy, highest linearity and smallest dimensions. These path sensors are used in hydraulic systems when it is necessary to control valves via a closed control loop.Schramme's proportional magnets and position sensors (LVDTs) form an assembly in which the gain and zero position have been calibrated and set at the factory.
