Do you know that oil filled pressure gauges can be used as non oil filled pressure gauges in most cases!
Oil filled pressure gauges can be used as non oil filled pressure gauges in most cases, but the following points should be noted:
Applicable scenarios: The oil filled pressure gauge is suitable for environments with severe vibrations, and can withstand the pulsation, impact, and sudden unloading of the medium. The instrument indication is stable and clear. The non oil filled pressure gauge is suitable for static or low-pressure measurement (such as laboratory, HVAC), but has poor temperature adaptability.
Maintenance and lifespan: The oil filling pressure gauge needs to be regularly checked for oil condition (recommended to be replaced every 2 years), as poor sealing may cause oil leakage. The non oil filled pressure gauge only requires cleaning the dial, but the gear wear rate is higher.
Economy: Under the same range, the price of the fuel gauge is 50% -100% higher, but long-term use can reduce the frequency of replacement, and the overall cost may be lower.
In summary, if your usage scenario does not require the special function of an oil filled pressure gauge and you can accept the possible increase in maintenance costs, then an oil filled pressure gauge can be used as a non oil filled pressure gauge. But when choosing, please be sure to consider actual usage needs and cost-effectiveness.
