What's In A Gauge And Why It Would Need Repairs
Even though a gauge looks like such a simple thing, it actually has lots of internal parts. If you were to open a gauge, you would see things like a loosely wound spring, a magnet, a dial that leads to the spinning arrow marker over the face of the gauge, the face of the gauge with all of its numbers and lines clearly indicated, and a few other parts. That said, gauges often need repair, as their delicate nature is vital to their proper functioning. Here are just some of the things that a gauge repair services company would look for when it opens a gauge to see why it is not working:
Dial Does Not Turn
The dials on gauges are turned by steam, pressure, or a magnetic force. When you know that there should be enough steam or pressure and the gauge does not register any changes, the service company looks for leaks in the gauge and the pipe or feed line leading into the gauge. If the gauge operates by magnetic force and does not register, the repair work needed often means that the magnetic system inside is busted. It has to have some components replaced to work again.
The Gauge Rattles Loudly
Gauges should not rattle. They might hum, but they should not rattle like a pressure cooker about to blow. If you send these gauges in for service or have a technician come to you, the technician will open up the gauges.
The partially unfurled springs inside maintain balance inside the gauge, but if they are loose, they will rattle loudly. It is similar to putting two marbles inside a small tin; if there is a marble on each side, no noise is made. If you move the marbles, they will start to roll and violently rattle the tin. The large spring inside a gauge is the same; it has to be positioned and fastened just right, or it rolls about. The technician will refasten or replace the spring coil and make sure it is balanced and secure.
Crunched Parts
Accidents happen, and if a particular accident caused the gauge to suffer a crunching blow, the whole gauge would need to be replaced. There would just be too much damage to the internal parts from damage to the exterior that it would cost more to fix the gauge than to just replace it. If that is the case, your repair technician will let you know.
