GP-X inductive analogue sensors (controller)
|
The inductive displacement transducers of the GPX series use eddy current techniques and are particularly noted for their highly accurate measurement at a resolution of 0.02% F.S. with minimal linearity error, a high sampling frequency of 40kHz and low temperature dependence.
GPX sensors are ideally suitable for the highly accurate motion and distance control of metal objects in harsh industrial environments. Characteristics: - High sampling frequency of 40kHz
- Resolution of 0.02% F.S.
- Minimal linearity error max. ±0.3% F.S.
- Minimal temperature dependence max. ±0.07% F.S./°C
- Bright, two-colour LCD display
- Preselectable materials (aluminium, steel, iron)
- Four measurement modes (preselectable)
- Cross talk prevention function
- Offset compensation and scaling functions
- Synchronisation input and alarm output
- Adjustable limit values with transistor outputs
Accessories: - Communication unit (optional)
- RS232 interface and BCD output (optional)
- Measuring and test software (optional)
