What is the working of oil level indicator of transformer?
The oil level indicator in a transformer is used to show the oil level.
How do you convert the analog fuel level indicator into digital in cars?
A: By adding an ADC analog digital converter but then again false triggering and monotonic and other errors makes this approach not desirable. unless heavily filtered the numbers will just rolls by filtering you get back again to analog response.
Do ammeters have batteries?
They don't need to, but if it is digital, it may have them. (Ohmmeters must have a battery)
What is level transmitter?
It just transmits the level of the fluid into electric signal to level indicator and this level indicator will show current level of fluid.The whole setup is used for level measurement. A Level Transmitter is simply an instrument that provides continuous level measurement. Level transmitters can be used to determine the level of a given liquid or bulk-solid at any given time. This is different to a level switch which only alarms when the level of material (liquid or bulk-solid) reaches a predetermined level.
What are the disadvantages of a digital multimeter?
An analog meter will respond to linearly as current is present . digital meters cannot do that not until the conversion is complete. in essence an analog meter is human friendly as compared to a digital meter. both have their places in applications.
