よくある質問 (FAQ)
-
Can this sensor system be used in high-vibration environments like gas turbines?
Yes. It is specifically designed for shaft vibration and position monitoring in high-vibration rotating equipment. -
Is the 4–20 mA output signal linear across the full measurement range?
Yes. It provides a linear analog signal proportional to displacement from 0 to 3 mm. -
Can I order the probe and cable separately?
番号 The probe, cable, and converter are factory-calibrated as a set and must be used together. -
What is the default cable length and can it be customized?
Standard lengths are 5, 7, and 9 meters, with custom lengths available on request. -
Is this sensor suitable for ATEX or IECEx hazardous environments?
Yes, optional ATEX-certified variants are available upon request. -
What types / materials can the sensor detect?
It is optimized for conductive materials like steel shafts and rotors. -
Is field calibration necessary?
番号 Factory calibration ensures accuracy. Field recalibration is not typically needed unless components are replaced. -
Can it be used to measure both axial and radial displacement?
Yes. The sensor is versatile and can be installed for axial thrust or radial shaft displacement monitoring. -
Is there built-in overvoltage or EMI protection?
Yes. The CON021 converter includes protection circuitry suitable for industrial EMC environments. -
How is this sensor installed and mounted?
