Magnetostrictive Sensors
Linear position sensors with a profile design are contact-free and absolute measurement systems for the precise detection of one or more positions. They deliver convincing performance in harsh environments, for example in presses, injection molding machines or gantry robots, because they are made of an hermetically sealed IP67 aluminum housing. The magnets of the position encoder act on the measurement element through the wall of the profile.

Force Sensors
The Force Sensors segment includes a broad line of load cells and force measurement transducers that are offered as precision sensors for industrial and commercial use. Typical applications for force sensors are in medical devices (such as hospital beds and medication dosing), agricultural equipment (for precision force measurement), and construction machinery (for tipping and overload protection). These sensors use our foil technology products, which serve as sensing elements and components within each unit. Further integration of our load cells technology is also offered as part of our weighing module products, which provide customers with a complete sensor assembly that may be used within a wide variety of digital transducers.

Current Measurement in a Compact Design
ICD-Series
Isabellenhütte Heusler GmbH & Co. KG
The ICD series is a compact system for current measurement. The ICD-A is suitable for an application in the automotive industry due to its connector, while the ICD-C is more suitable for the design industry. The shunt-based measurement provides for a high level of accuracy and temperature compensation is also incorporated through the internal signal processing. External temperature influences are thus reduced to a minimum.

Precision Current Sources
HighFinesse Precision Current Sources have been developed for experiments and quantum technologies in the areas of cold-atom and solid state physics. The linearly regulated BCS (Bipolar Current Source) and UCS (Unipolar Current Source) series deliver highly stable, low noise source currents for high precision magnetic field control. The current output is floating or is on a used defined potential. Ultrafast response to control signals and trigger functions, clear grounding, connection and signal isolation schemes make the integration of the current sources into complex experimental systems easy.
