Normally you want a pressure guage at its maximum pressure to be around 70-80% of its range.
With such a large discrepancy, you need to figure out what the maximum pressure the line will see regardless of its design pressure.
Get it wrong and you break the guage if it goes off scale ( if you get a single large pressure once) or means you're operating at 10-15% of range ( if you go for 200 bar range).
Over pressure protectors can be fitted but are not very reliable and can prevent you seeing a large pressure as the guage will freeze at what ever you set the over pressure protector to. They sometimes don't all the pressure to fall and get stuck closed.
Or get a digital readout from a transmitter.
