FAQ
1. What is the required target material for proper calibration?
The probe is calibrated for use with AISI 4140 steel or an equivalent material with a relative permeability / μr ≈ 1. Using a different material will affect the output sensitivity and require recalibration.
2. Can the extension cable be spliced or repaired if damaged?
番号 Splicing or repairing the coaxial cable is not recommended. Any alteration can change the cable’s capacitance and electrical characteristics, which will severely impact system calibration and measurement accuracy. The entire cable must be replaced.
3. What is the purpose / the gap voltage?
The gap voltage (or average DC voltage) represents the average distance between the probe tip and the target. It is used to set the probe’s initial installed gap within its linear range to ensure accurate AC vibration measurement.
4. How does temperature affect the probe’s operation?
Temperature changes can cause thermal growth / the machinery and slight drift in the probe’s electronic characteristics. For critical applications, a dual probe setup (X-Y configuration) is used to compensate for this radial shaft movement.
5. What could cause a -24 VDC power supply alarm on the monitor?
This alarm typically indicates a short circuit in the probe system. Common causes include damaged cable insulation, a compromised connector submersed in fluid, or a internally damaged probe.
6. Why is the signal output measured as negative voltage?
The system is designed to provide a negative voltage output relative to the common ground. This is a standard design convention for eddy current proximity systems and is correctly interpreted by the associated monitoring hardware.
7. What is the maximum cable length for this system?
The standard system is optimized for the specified cable length (e.g., 5m). Significantly longer cables can introduce capacitance issues and signal degradation. For longer runs, it is crucial to consult the system specifications or use a preamplifier located near the probe.
8. What is the difference between a probe’s linear range and its total range?
The linear range (e.g., 80 mils) is the distance over which the output signal has a guaranteed linear relationship with the target distance. The total range is larger but non-linear; operation in the non-linear range leads to inaccurate measurements.
9. Can this probe be used to measure vibration on gear teeth?
While possible, it is not ideal. The changing geometry / gear teeth as they pass the probe creates a once-per-revolution “output runout” signal that can be mistaken for vibration. A dedicated gear tooth sensor is recommended for such applications.
10. What does the part number suffix ‘-02-00’ indicate?
This suffix typically denotes the specific revision or version / the connector and packaging kit. It is essential to use the full part number to ensure you receive the correct, compatible components.
