Position Sensors, Angle, Linear Position Measuring Q & A
Q: What's the typical lifespan of industrial position sensors?
A: Quality sensors last 5-10 million cycles. High-end models can exceed 50 million cycles with proper maintenance.
Q: How do I calibrate angle measurement devices?
A: Most modern devices feature automatic calibration. For manual calibration, use certified reference standards.
Q: What's the difference between absolute and incremental encoders?
A: Absolute encoders maintain position after power loss, while incremental encoders require homing.
Q: Can I use the same sensor for linear and angular measurement?
A: Some multi-axis sensors can measure both, but specialized devices typically offer better accuracy.
Q: How important is IP rating for factory floor applications?
A> Critical. IP65 is minimum for most industrial environments, with IP67/IP68 needed for washdown areas.
Q: What's the lead time for custom sensor solutions?
A> Typically 4-8 weeks for modified standard products, 12-16 weeks for fully custom designs.
Q: Are Chinese-made sensors comparable to European or American brands?
A> Many Chinese manufacturers now produce components meeting or exceeding international standards, often at 30-50% lower cost.
