Product Advantages in Application
When used in machinery protection systems, this sensor provides continuous, real-time measurement of shaft movement. The data collected allows predictive maintenance teams to identify imbalance, misalignment, or bearing issues before they escalate. The sensor’s ability to operate in contaminated environments ensures reliable performance even when exposed to oil film or metallic particles, which are common in turbine and compressor housings.
FAQ
Q1: What type of output does the PR6423/003-131+CON041 provide?
A1: The sensor provides a voltage output signal proportional to the measured displacement, typically in the range of millivolts per micron.
Q2: Is the sensor compatible with other Epro CON modules?
A2: Yes, it is compatible with various Epro CON series converters, including CON041, CON042, and CON021, depending on system requirements.
Q3: How is the calibration of this sensor performed?
A3: Calibration is typically carried out using a micrometer setup under controlled conditions to ensure accurate linear response within the specified measuring range.
Q4: What is the typical frequency response of the sensor?
A4: The sensor supports a frequency range from DC up to 10 kHz, suitable for dynamic vibration and displacement measurements.
Q5: How should the sensor be mounted for optimal accuracy?
A5: It should be installed perpendicular to the target surface with the correct initial gap (nominal 2 mm) for linear output response.
Q6: Can this sensor be used in oil-lubricated machinery?
A6: Yes, it is specifically designed to perform accurately in oil-rich and contaminated environments.
Q7: What cable length options are available?
A7: Standard cable length is 5 meters, but customized lengths up to 10 meters are available upon request.
Q8: Does temperature variation affect measurement accuracy?
A8: The sensor compensates for temperature drift through internal design, maintaining stable readings across its operating temperature range.
Q9: Is the PR6423/003-131+CON041 suitable for monitoring axial displacement?
A9: Yes, it can measure both radial and axial displacement depending on installation orientation.
