FAQ
FAQ
Q1. What is the PR6424/118-021 used for?
It is a non-contact eddy current displacement sensor designed for measuring shaft vibration, displacement, eccentricity, and position in rotating machinery such as turbines, compressors, and pumps.
Q2. What measurement range does the sensor provide?
It offers a static displacement range of ±2.0 mm and can measure dynamic shaft movement up to approximately 1,000 µm.
Q3. What are the physical dimensions of the PR6424/118-021?
Sensor head diameter 16 mm × body length approximately 40 mm × cable diameter about 2.8 mm × standard cable length 1 m.
Q4. What mounting thread does the sensor use?
The probe is installed using an M18 × 1.5 threaded body for secure mounting in machine housings.
Q5. What temperature range can the sensor operate in?
The sensor operates reliably in environments from −35 °C to +180 °C, making it suitable for harsh industrial applications.
Q6. What type of target surface is recommended?
It is optimized for ferromagnetic steel targets such as 42CrMo4 shafts to ensure stable and accurate measurements.
Q7. Does the sensor work directly with control systems?
No. It normally connects to a compatible signal converter or transmitter module to generate usable monitoring outputs.
