Professional FAQ
- Q: Does the cable length impact my system linearity?
A: Yes, total system length must account for both probe and cable to ensure the Proximitor sensor operates within its calibrated linear range. - Q: Why is the FEP jacket crucial for high-temperature applications?
A: FEP provides superior thermal stability and chemical resistance, preventing the cable from becoming brittle in harsh industrial atmospheres. - Q: What wiring type should I use for the field connection?
A: We recommend using three-conductor shielded triad cable to minimize EMI, especially if your monitor distance approaches the 305-meter limit. - Q: How do I identify potential cable damage during routine maintenance?
A: Check the gold-plated connectors for oxidation and perform a continuity test to verify resistance against the standard 0.220 Ω/m. - Q: Is the stainless steel armor necessary for my installation?
A: Armor is highly recommended for environments with high mechanical vibration or risks of physical impact to ensure long-term cable protection.
