Frequently Asked Questions (FAQ)

Here are answers to common questions about this specific 330703-000-178-10-02-00 model.

• Q: Can I use this 1.0-meter probe with a standard 5-meter Proximitor?
  A: No. This 1.0-meter probe requires a 1.0-meter Proximitor® Sensor for correct system calibration and linearity.
• Q: What is the difference between the '02' and '11' cable options?
  A: The '02' option includes a miniature coaxial ClickLoc™ connector with a standard cable, while '11' uses a FluidLoc cable designed for high-moisture environments.
• Q: What does the longer 178 mm case length accommodate?
  A: The 178.0 mm overall case length suits installations where the probe must pass through a thicker barrier or where extended reach is necessary before the tip.
• Q: Is the connector field-installable?
  A: The miniature coaxial ClickLoc™ connector provides a rugged, secure connection. It is designed for reliable field use, but we recommend factory-terminated assemblies for best performance.
• Q: How does the PPS tip benefit my application?
  A: The PPS tip material provides excellent dimensional stability and chemical resistance, ensuring consistent performance even when exposed to lubricants and process fluids.
