Dial type vs. Pen type tire gauge

[russpogi]

pen-type for me. but buy a branded one. ung made in US or japan. ung mga dial type is just a coil spring inside. sa kin is stainless steel ung casing and plastic-type ung slider. very consistent ung reading. handy pa..

Same here. I love the fact that it's handy.

pen-type din yung nabili ko, P400.00 made in japan solid brass construction.

It doesn't make any difference whether they are pen, dial or digital, just make it sure they are properly calibrated to the correct readings.

I don't know which is more accurate. But I've been using the dial type. I bought 1 in 1989 and I'm still using it.

pen type ang gamit ko, freebie lang. though hindi ko alam kung gano ka accurate, mejo ini-estimate ko na lang. kasi pag nagpahangin ako sa caltex, +2 psi yung sa dial type na ginagamit nila. yung sa shell (digital) -1 psi.

so how would we verify if they are properly calibrated?

sa akin dial type din, mas madali kasing basahin. But now i just go to shell gasoline station meron silang air pump with gauge , set lang to your desire tire pressure then automatic nang nag-stop

Buhayin ko po thread na ito.

Pano po malalaman kung un bibilin mong guage eh pede i-calibrate? Or lahat naman naa-adjust?

Saan po pede magpa calibrate?

Iba2x kasi nakukuha sa tires ko sa mga shops d2. Un isa, Goodyear Servitek pa man din, pero sobrang baba sa dial type nila na malabo namang mangyari kasi d naman mukang flat, ok naman marks nya sa kalye kung basa, at ayus naman FC ko.

Salamat po.

i don't think that the off the shelf tire gauges can be calibrated.

though I do check from time to time my tire gauge's reading against the digital reading found in some gasoline stations. it's still pretty accurate.

The biggest difference, I feel, between 'stick'(plunger) and clock/dial tire gauges, is technique.

Make sure both the gauge end and the tire valve are clean and free of crud, and seat the gauge firmly to the tire valve.

Repeat if necessary, especially if you hear air hissing by. Milton(USA) still makes among the best quality sticks, and they're always no more than 1psi off from my dial kits.

I find the stick/ plunger to have one(slight) advantage: Being only 4-5inches long, it can provide a more direct read of air pressure, compared to those dial gauges which have 12-16 inches of hose with the tire chuck at the other end. You 'donate' a bit more air from your tire with one of those, vs with a stick gauge.

While plungers are built mostly on the same principle(plastic or metal scale inside an internal diaphragm inside a metal body), dials can employ a variety of configurations, based partly on cost.

There's the coil-spring dial gauge mentioned previously, and something called a Bourdon tube design(named after its inventor).

Recall the party whistle you blew on at birthday parties, where a long paper or plastic banner unrolled from the whistle when blown into. That is exactly how the Bourdon principle works!

In a Bourdon pressure (tire or other purpose) gauge, air, or steam, pressurizes - and attempts to straighten - a curved brass metal tube inside, which is by calibrated gears linked to the gauge pointer. The pointer then rotates up to the indicated pressure, in whatever scale(kp, PSI, kg) is required.

More expensive gauges, like the Longacre brand I use back in the U.S., also employ a dampening system of which I don't fully understand, but is cool to see the pointer sweep slowly up to the indicated pressure, then slowly return to zero after dumping the reading(pressing the air bleed button). If you have PHP3,000 laying around, you can look up Longacre Racing or Intercomp, and buy one of their tire gauges. You'll never second guess tire pressures again.
