Anti-Corrosion Hongqi Differential Pressure Gauge, Stainless Steel Material

Slight short-term overload (≤1.2×full scale): Short pressure impact usually won't cause permanent damage. Accuracy can remain stable after pressure release. Repeated minor overload will accelerate bellows fatigue, gradually leading to zero shift and larger measurement error.

Pressure exceeding allowable overload: The bellows will have permanent plastic deformation, resulting in zero drift. The measurement error will exceed the tolerance permanently and cannot be recovered.

Severe overpressure: Bellows may stretch or crack, the gauge fails completely and loses measurement function.
