The principal thing you really want to realize while choosing a tension measure is what the future holds (square inch, or “psi” is standard) you really want. Since the precision of most tension checks is best in the center third of a measure, you should constantly choose a check with a reach that is regarding double your typical working strain. For instance, assuming that you have an air blower with an ordinary working tension of 50 psi you need to choose a measure with a 100 psi range.

The guideline with pressure measures is that while the working tension of the framework is ordinary, the needle ought to point straight up or in the “twelve o’clock” position. This makes the measure simpler to peruse initially – on the off chance that the pointer is straight up, things are typical. Checks are generally exact in the center third of their reach, so you’ll likewise improve estimation at your most regular strain.

On the off chance that you can’t track down a check at precisely double your functioning strain, go to the following stage up. For instance, on the off chance that you need a 160 psi check and it isn’t available, a 200-psi measure can be subbed. Assuming the reach is too low and the measure is over-compressed it will break. You need a space in excess at the highest point of the scale so that assuming your strain goes better than average, it won’t harm the check.

Dial size alludes to the width of the roundabout essence เกจวัดแรงดัน of the check. The most straightforward method for picking a size is to quantify the distance across of your old check. Measures range in dial sizes from 1-inch for restricted spaces to 10-crawls for perusing from a good ways. While choosing a check pick one that fits inside the actual space accessible and a measure size that is not difficult to understand where you have it introduced.

In the event that dial size isn’t essential to you consider choosing a 2 ½” check. Assuming there is such an incredible concept as a “standard” check size, this is it. The 2 ½” measure is by a long shot the most widely recognized check size and you will observe many choices in that size range. You can likewise see the producers’ layered drawings assuming you want more data.

There are two fundamental association types for mounting: back and lower. The back mount is what the future holds. The association distends from the rear of the check. In a lower-mount (now and again called a stem mount), the association is on the lower part of the check. Which type you want will as a rule be really self-evident. Producers partition back mounts into “focus back” and “lower back,” (directly in the center of the back versus down toward six-o’clock), yet except if you’re attempting to squeeze the measure into a restricted space, or mount it in a board, the distinction typically doesn’t make any difference.

You likewise need to consider association size. For 2-1/2″ dial measures, a 1/4-inch NPT (National Pipe Thread) is by a long shot the most widely recognized size. Assuming that you’re supplanting a check, you need to know about the current association size. Other normal association sizes are 1/8-inch NPT (for 1.- 1/2″ and 2″ dials) and ½-inch NPT (for 4″ and more noteworthy dial sizes).
