常见问题

What are the key material considerations for probe tube bodies?

Material selection depends on application requirements: stainless steel for corrosion resistance, aluminum for lightweight applications, and titanium for high strength-to-weight ratio. All materials must maintain dimensional stability across the operating temperature range.

How does tube body straightness affect measurement accuracy?

Straightness deviations cause sensor misalignment, leading to measurement errors proportional to the deviation. For high-precision applications, straightness tolerance should be ≤ 0.05 mm/m to ensure measurement accuracy within specified limits.

What maintenance is required for probe tube bodies?

Regular inspection for surface damage, cleaning to prevent contamination buildup, and verification of dimensional stability. Periodic calibration checks ensure continued measurement accuracy.
