Any industry today that relies on heavy machinery, servo mechanics and the like relies on measurement more so than any other aspect. In fact, when it comes to most industries in general, it’s almost always a priority to be able to measure different types of objects and specimens accurately. Even industries such as laundry and baking rely on measurement when it comes to getting the job done – otherwise, it simply doesn’t work. From factories to the creation of satellites, the ability to measure is something that can never be underestimated.
That said, what would be the very best type of measurement device available? It’s not an easy question to answer as there are plenty of industrial devices that work in several industries to accomplish the same goal. However, when it comes to industries that rely on precise numbers more so than any other – the answer becomes much clearer. In order to precisely translate force, vibration and weight into quantifiable numbers, the linear variable differential transformer is vital.
How does the linear sensor work?
The LVDT works by measuring the movement of objects through the use of an electrical current. With these specific voltages, it can be possible to figure out the force or vibration as well as pressure and load of the objects in question. One of the reasons why it’s more popular than most is the fact that it is both precise and durable. Normally you would only get one or the other, as precision requires industrial grade equipment but the constant repetition would wear it down no matter the situation. The linear sensor, on the other hand, is well known for having a low amount of hysteresis – which means that repetition isn’t an issue for the linear sensor.
Different linear sensors for different situations
Aside from being the most useful of the inductive transducers, there are plenty of different types available to fit any situation. For example, a captive armature linear sensor is used specifically for much longer ranges. On the other hand, you also have the submersible sensor which is a linear sensor that specialises in precise measurement in subsea conditions. The submersible linear sensor can even withstand pressures all the way to 5,000 psi.
What to watch for when choosing a linear sensor
While the LVDT is certainly one of the most popular types of inductive transducers around, it’s essential that you understand what kind of sensor you need for the job. For example, while you might be able to use the general linear sensor in subsea conditions, it won’t last very long. Instead, the submersible LVDT is the perfect instrument to be used. On the other hand, the unguided armature boasts no limit as far as resolution goes – giving you the freedom that you need to work with the measurements.
To conclude, there can be no doubting the ability of the linear sensor to translate movement, vibration, pressure and many other dimensions into the numbers that companies need to move forward.
