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.
