Seismic pressure gauge filling fluid
Thread Content
May I ask, does a seismic pressure gauge necessarily need to have a filling liquid inside? Are there shock-resistant pressure gauges that don’t require filling fluid?
Go and find out what the filling fluid does; I really have never seen anything without a filling fluid
There should be a filling liquid; I’ve never seen one without it.
I’ve never seen a shock-resistant pressure gauge without a filling fluid.
I’m just asking around – is it expensive to fill it with fluorinated oil, and does its lifespan not be long either?
What does the digital pressure gauge you mentioned look like? Is it explosion-proof? Explain it to us. Post another one; anything in the style of an advertisement is fine.
On-site meters have their advantages; never rely on digital meters.
Hello, you can take a look at our company’s website at www.wu*hanle.cn. It offers digital pressure gauges that are powered by batteries, specifically 1.5V or 3V batteries; they can be used for 2-3 years under normal conditions.
