Typical Applications & Selection Advice
This 178mm long-case probe is designed for specific applications. It is used where the sensor must pass through a thick housing, insulation layer, or adapter before reaching the target shaft. Common in large turbines, generators, and custom machinery. Select this model only if your technical drawings specify a long-case probe.
Expert FAQs
Q: When would I need a 178mm case instead of a standard 40mm or 60mm case?
A: You need the 178 mm case when the distance from the mounting surface to the target (shaft) is very large. This happens with deep bearing housings, when using special adapters, or when mounting through insulation jackets on machinery.
Q: Does the longer case affect the probe’s sensitivity or electrical performance?
A: No. The case length is a mechanical design feature. The internal sensing coil and electronics are identical to shorter probes. The electrical specifications like resistance and scale factor remain the same.
Q: Is the cable on this model also extra-long?
A: No. The cable length is a separate option. This model (-10) has a standard 1.0-meter integral cable. The “178” refers only to the metal case length. You can use extension cables to reach your monitor.
Q: How do I properly install such a long probe to avoid damage?
A> Support the probe body during installation. Do not let it hang unsupported by just the threads. Ensure the mounting hole is clean and deep enough. Use the recommended torque of 21.1 N·m. Avoid side-loading or bending the long case.
Q: What is your return policy and how can I get a quote for multiple units?
A> We accept returns for unopened, factory-sealed items. For technical compatibility issues, contact us first. For volume pricing on the 330703-000-178-10-02-00 or other models, please email our sales team directly for a custom quote and fastest shipping options.
