While using a pressure gauge, people sometimes notice that the gauge's pointer suddenly becomes shorter, upon closer inspection, they realize that half of the pointer is missing. A broken pointer is a severe fault, rendering the pressure gauge unable to perform its basic function of displaying pressure readings.
There are two reasons for the broken pointer of the pressure gauge:
Generally, a pointer is broken due to its soft material and poor rigidity, which can bend or even break upon certain impacts.
Due to improper operation by on-site staff, such as rapid depressurization, the pointer repeatedly hits the stop钉 at a high speed, leading to its eventual breakage after multiple occurrences.
The pressure gauge pointer was broken, primarily due to the manufacturer's responsibility. The pointer's rigidity was insufficient, or there were inadequate warnings (such as reminding users to install a pressure damper or overpressure protector in specific environments or when measuring special pressures).
The pressure gauge pointer was broken. The user should first contact the manufacturer to determine the cause of the pointer breakage (this is to ensure the safety of other instruments purchased in the same batch). If the issue is due to the manufacturer, it is necessary to promptly inspect the pointers of other pressure gauges. If it is due to improper use, the user should correct it immediately.
When purchasing pointer materials for pressure gauges, the pressure gauge manufacturer must ensure they meet the requirements specified in the design drawings, with the correct grade and mechanical properties, especially rigidity. For special-purpose pressure gauges, such as those for the domestic market that do not meet design requirements, materials should be imported from abroad, or negotiations can be conducted with the customer to select alternative materials or terminate production. Users of pressure gauges should operate them strictly according to the instructions in the pressure gauge manual. In case of necessity, pressure dampers or overpressure protectors can be installed to protect the gauge pointers from damage.
