Instrument buzzer purchase considerations
Time:2018/1/30 21:00:43  Browse:

As the name suggests, meter buzzer refers to buzzer products commonly used in instrumentation. Like ordinary products, its purchase also follows a certain principle, that is to consider according to its own product parameters. The specific content we will detail below for everyone.

Parameter one: size

As we all know, the size of the buzzer will affect the size of the volume, so we must carefully consider this factor. As far as the frequency is concerned, the electromagnetic minimum is from 7mm to 25mm, and the piezoelectric type is from 12mm to 50mm or more.

Parameter two: operating voltage

Specifically, the working voltage of the electromagnetic meter buzzer can be from 1.5 to 24V, and the piezoelectric type can be from 3V to 220V. However, the piezoelectric is generally recommended to have a voltage of 9V or more. Big sound.

Parameter three: consumed current

The buzzer consumes different current depending on the voltage. From tens to hundreds of milliamperes, the piezoelectric type is more power efficient, and can operate normally with a few milliamperes, and when the buzzer starts up, it takes about three times as much current to consume.
