Spanish term

por obturación directo/indirecto

Spanish to English Tech/Engineering Engineering (general) Metrology
I'd be grateful if anyone could tell me the translation for 'por obturación directo/indirecto' when talking about pneumatic comparators please. Here's the context:
Proposed translations (English)
2 direct/indirect sealing/plugging

Discussion

Sandra Meneaud (asker) Mar 21:
In the end I'm going to go with:
Flow (or) velocity type pneumatic comparator
Back pressure type pneumatic comparator
Differential pneumatic comparato

after reading these lecture notes which refer to adjusting the flow of air through a tapered glass tube.

Thanks once again for all your suggestions.
Robert, how do I award you points?
Sandra Meneaud (asker) Mar 21:
Yes, thanks for your input Robert. I have seen those types mentioned on the Solex websites, and also considered them. I think though that the three points in the slide refer to the way air pressure is regulated, and I'm not sure those types reflect that idea. I've copied and pasted those three types on the Solex website in a note to self, and will go back to it.

Liz Askew asks But why is the adjective masculine? I believe the adjective may be connected to the word "comparador" rather than "obturación", i.e., comparador directo (por obturación), comparador indirecto (por obturación)

Have you looked at pneumatic comparators (or Solex air gauges) as described in English texts?

"Pneumatic Comparator Types
These comparators are normally available in three types which are discussed below.

Flow/Velocity type Pneumatic Comparator.
Back Pressure type Pneumatic Comparator.
Differential type Pneumatic Comparator."
https://www.elprocus.com/pneumatic-comparator/

"Types of pneumatic comparator
Basically, the pneumatic comparators are classified into three types.

Flow (or) velocity type pneumatic comparator
Back pressure type pneumatic comparator
Differential pneumatic comparator"
https://www.engineeringtribe.com/pneumatic-comparator/

Question remains as to which ones are which.
If I had to hazard a guess I'd say:
por estrangulación = flow type
por obturación directo = back pressure type
por obturación indirecto = differential type
philgoddard Mar 20:
I found 'restriction' in a couple of documents on Solex comparators, but I don't know whether that's 'estrangulación', or 'obturación', or neither.
neilmac Mar 20:
My take I like "indirect/direct /shutoff, but don't really know enough about the field to post an answer.
Sandra Meneaud (asker) Mar 20:
Although I think after looking at the comments below, perhaps 'shut-off valve' might be better here instead of 'throttle'
Sandra Meneaud (asker) Mar 20:
Yes, I did consider 'obturation' and 'sealing', but can't find anything related to pneumatic comparators when I do a search with these terms.

Thanks for the link Phil, I consulted this website too.

I translated it (tentatively) as 'throttle' - I suppose like the throttle in a car engine. I think it's right according to the websites I've seen.
philgoddard Mar 20:
A pneumatic comparator compares components to a standard one, to ensure they're the right size.

Have you considered 'obturation'? It means obstruction, but I'm not sure if that's the right word either.

How have you translated 'estrangulación'?

HS701 pneumatic comparator from Huaxin is designed to generate vacuum and pressures for testing, adjusting and calibrating mechanical and digital pressure measuring instruments by means of comparative measurements. It combines the functions of three pressure pumps and minimizes the number of equipment carried for on-site calibration.

Features

1. With uniquely designed air capacitor and shut-off valve, the pneumatic pressure comparator acts more stably in calibration of micro pressure gauges.
2. Fine adjustment valve that reaches an accuracy of 0.01mbar (1Pa) allows it to calibrate -0.25~0.25bar pressure gauges.
3. Two pressure outputs of the pneumatic comparator come with standard M20x1.5 connectors that ensure quick connection and disconnection of gauge under test without need of wrench.
4. Designed in compact and beautiful housing, the pneumatic comparison test pump is easy to operate, portable and stable in pressure rising.
5. Fabricated from superior alloy in special process, it provides remarkable robustness.
6. The pneumatic comparator applies circulating air circuit design and comes equipped with a built-in impurities precipitation system that leads to easy maintenance.

1. Hand pump

Uplift the hand pump and press it down repeatedly to generate vacuum and pressure.
2. Lead screw

Increase pressure by turning the lead screw clockwise, decrease pressure by turning the lead screw anti-clockwise.
3. Reverse valve (positive/vacuum)

Press the button to switch between positive pressure and vacuum. (Push for positive pressure calibration and pull for vacuum).
4. Relieve valve

Have to turn clockwise to close the valve before pressure generation, and slowly turn it anti-clockwise to release system pressure.
5. F-adjust valve

The valve is equipped for precise adjustment of pressures. Turn clockwise to increase pressure and anti-clockwise to decrease.
6. Plug

Screw it up when not in use. It prevents dust and other matters entering the port.

7. Pressure Port (Output)

There are two pressure output ports: one is designed for reference measuring instruments and another for gauge under test.
8. Air capacitor

The container of air
9. Shut-off valve

Open the valve when calibrating small range gauge (-0.25~0.25bar)

What's Included in the Package
Note from asker:
Many thanks again Liz. I think I may have to go with 'sealing', unless any expert on pneumatic comparators comes up with a better term.
Hi Liz, I'm going to have to park this one for the moment and come back to it. I'm undecided between your suggestions and the ones Robert made above. Huge thanks again.
