IMS Measuring System

The IMS position sensor is ideally suitable for installation in hydraulic cylinders thanks to its compact and study design. The technology is based on a linear variable differential transformer (LVDT). This electromechanical sensor consists of a moving core and a stationary coil system. This analogue sensor measuring absolutely has a range of important advantages:

• Non-contact measurement / Long service life
  All parts moving relative to one another are non-contact. Good encapsulation of the coil system (IP68) and the absence of friction ensure a long service life, even under tough environmental conditions.
• Absolute position signal
  The analogue sensor supplies a position signal immediately after switching on the power supply. A reference movement is not required.
• Good zero point stability
  The symmetrical structure of the coil system ensures good zero point stability and a repeat accuray.
• Integrated electronics
  The evaluation electronics of the LVDT are an integral component of the sensor, with the result that a standard signal available at the interface to the control.
• High pressure resistance
  The pressure resistance of the IMS system is limited almost exclusively by the cylinder design.
• Good dynamics
  The low moving mass of the core ensures goods dynamics of the LVDT, which is only limited by the processing speed of the electronics.
• Large temperature range
  The standard sensor works in a wide temperature range from -20°C to +85°C. The temperature compensation of the electronics guarantees an almost constant measuring value in the entire temperature range.
• Very good vibration resistance
  Vibrations have practically no effect on the sensor signal
• Large mechanical tolerances
  Errors in the diameter and angular position of the core and coil system are uncritical, which is crucial for the high functional reliability of the systems.
• For use with all pressures fluids
  The IMS system is suitable for both water-based or synthetic pressure fluids.
