Temp Gauge for Hydraulic Fluid

[RickB]

My contention is that there is no increased flow, nothing is moving faster, due exactly to the restriction points. Without increased pressure, there is nothing to push more fuid through those points.

What you have now is the ability to run more implements simultaneously.

There’s so many things wrong here I don’t know where to start.
He put on a larger pump; how is there not more flow?
How do you know that restrictions are limiting flow?
Let’s pretend there ARE restrictions. How would they NOT create more heat?
If there happens to be restrictions to the additional flow, measured pressure between the pump and restriction WILL be higher.
When valves in an open center system are plumbed in series without a flow divider, simultaneous operation is not a given, only a possibility dependent on variables not known here.

Infrared hand held thermometer for 30 to 40 dollars are lowes. Can check any point you want to with one tool.

And there is a useful tool available for other things.

They are getting more popular these days HF has them on for 20 bucks from time to time. I have 2 and both work just fine. I was going to suggest the same as I use mine on everything. Really amazed at how cool things really run when you expect them to be sizzling hot.

As I recall at about 70C if you put your finger/hand on an object you have to immediately take it off. No burn involved, just uncomfortable enough to make you want to do it. That's 158F if I did my arithmetic correctly. For a benchmark, US domestic hot water heaters (of which I know) in the N position produce 140F water.

Fluid can get well over 230F before you have to start worrying about temp.

Thanks Rick for clearing that up. I thought for a second that I was loosing it.

Thanks everyone for your help. I will get a infrared thermometer to check things out. I still would like to get the gauge working if I can so I can monitor temps on a ongoing basis. My hope is to keep the temp below 180F if possible.

Should be a good location for your gauge once you get the probe in the fluid flow.
