In most industries, achieving precise measurements isn’t just recommended – it’s a requirement. It’s not something that you can achieve by utilising just any instrument as there are many different aspects of measurement. For example, baking would require devices capable not only of precise measurements but the durability to handle constant repetition. When it comes to applications such as hydraulics or even satellites, it becomes doubly crucial for the instruments being used to be able to give the most accurate measurements possible.
It’s where the linear variable differential transformer comes in. Its primary function is to translate movement and mechanical vibrations into a specific voltage or electric current, which includes the reverse flow as well.
The different kinds of LVDT
There are different types of LVDT sensors that are being used today, which include:
- Captive armature. A sort of LVDT sensor that is mainly used for longer ranges.
- Force-extended armature. A unique type of sensor that doesn’t require a connection between the armature of the specimen being measured. Primarily, the force-extended armature is used for slower moving objects and overall applications.
- Unguided armatures. A type of sensor that doesn’t have a limit with regards to resolution qualities. While it requires the transducer to have separate support, the limitless resolution can provide satisfactory results.
Aside from the types of LVDT, there are also different types of sensors. One example is the RVDT or the rotary variable differential transformer. It’s considered more effective when it comes to industrial machinery that requires constant and arduous work.
Why go for LVDTs?
While there are other instruments out there capable of precise measurement, there’s no denying the fact that the LVDT is more than enough when it comes to measuring pressure, force as well as load. Its advantages become especially apparent when used in industries that make use of servomechanisms. From jet turbines to hydraulics to aircraft, the linear variable differential transformer is an invaluable device that is both durable and efficient. When it comes to the inductive transducer, the LVDT is known to be the most useful type of sensor around.
Are there any disadvantages?
Just like any device, the LVDT has some possible disadvantages, and it would always be best to be aware of these before committing to using these devices. While it’s capable of being used in many different situations, it’s important to be mindful of the fact that it can be damaged by factors such as temperature or even vibrations. It’s essential that you’re aware of the type of LVDT that you’re using, as the different kinds of sensors excel in certain situations.
To conclude, when it comes to inductive transducers, you can’t go wrong with the LVDT. Not only is it capable of precise measurement, but it’s also very hardy and durable, making it perfect for repetition. Because most industries operating heavy machinery require repetition, devices like the linear variable differential transformer are given a chance to shine. If you’re looking for a means to measure equipment and machinery through inductive transducers, look no further than the LVDT.
