How Much Nitrogen Gas and Pressure Are Needed for a 250°C Temperature Gauge?

AI Thread Summary
The discussion centers on determining the amount of nitrogen gas and the required pressure for a temperature gauge with a 250°C range and a 2-meter capillary tube. Participants highlight that the gas volume needed is contingent on the specific gauge or sensor used. Clarification on the make and model of the tube and gauge is requested to provide accurate calculations. There is confusion regarding the relevance of a link to flow measurement when the focus is on temperature measurement. Accurate specifications are essential for calculating gas volume and pressure requirements effectively.

Hi,

I Have one Temperature gauge with 2Meter Cpillary. Range is 0-250Deg Centigarde. it was field with Nitrogen gas immersion length (sensing element) was 100mm in the process.
How much gas should field to get the 250Deg Centigarde temperature. and how much pressure is required to field the 'X' amount of gas.

How to calculate these kidly let me know.

Hi,
I have question on gas field temperature gauges. Question: I have a tube OD 10 mm X 1.0 mm WT(wall Thickness) X 100 mm. Temperature range '0 to 50 Deg Centigrade. I want to fill the Nitrogen gas in the tube.

Total Tube Length: 200 mm & Imersion length: 100mm. (i.e; Imersion length is nothing but sensing element, which is used in process).

1. how much gas should fill it?
2. How much pressure is required to fill 'X' amount of gas?

Kindly help me out on this.

The gas volume needed will depend on the gauge or sensor fitted to the tube.

What is the make and model of the tube you are using ? Please attach a link to manufacturers site.

Why do you give a link to Flow Measurement if you want to measure Temperature?
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
