FAQ
Frequently Asked Questions (FAQ)
Q1: What is the primary function of the PR9268/200-000 sensor?
A1: It is designed to measure absolute vibration velocity in vertical direction for condition monitoring of rotating machinery.
Q2: Can this sensor be used in hazardous environments?
A2: Yes, this model is certified for use in hazardous areas when installed with proper safety barriers and compliant to EN IEC 60079-14.
Q3: What are the allowable mounting angles without lifting or sinking current?
A3: Vertical models like the 20x series allow ±30° deviation without current compensation; up to ±60° with sinking current applied.
Q4: What electrical load is recommended for optimal operation?
A4: A load of 100 kΩ is recommended to achieve specified sensitivity and frequency response.
Q5: How should the sensor be mounted for accurate measurements?
A5: It should be mounted on a clean, flat, vibration-free surface using the provided mounting holes and torque settings.
Q6: What type of output signal does the sensor generate?
A6: The sensor generates a dynamic analog voltage signal proportional to vibration velocity in mV/(mm/s).
Q7: What cable configurations are supported?
A7: The sensor is available with armored or non-armored cables ranging from 3 to 10 meters, with Harting plug or open cable end.
Q8: Is periodic maintenance required for this sensor?
A8: No periodic maintenance is needed under normal conditions. Diagnostic checks can be performed via resistance and insulation tests.
