V. Difference from Ordinary Vibration Probes

Usage: 330980 is for phase picking/rotation speed specific; 330104 is for shaft vibration/displacement specific

Temperature resistance: 330980 has a temperature resistance of up to 175℃, suitable for high-temperature areas; ordinary probes have a maximum of 125℃

Signal characteristics: 330980 focuses on pulse integrity; ordinary probes focus on linear measurement range accuracy

Working conditions: 330980 must be used in the high-temperature section of gas turbines, and cannot be replaced by ordinary probes
