The adjustable impact intensity technology that is introduced in the latest generation of automatic bell ringing mechanisms of our company, achieves optimal sound performance in every bell regardless of each bell’s mold shape or size. Though the capabilities of our mechanisms, we give solution to many of the problems that could not be effectively solved by the earlier bell ringing solutions on the market.

Below you can find out more about the benefits of adjusting the power of bell ringing.




Each bell, when it comes out of the foundry it is coupled with a clapper, each clapper is weighed and made particularly for the size and weight of the bell.

In order to achieve the optimal sound quality in every bell, we had to create a mechanism that could accurately adjust the intensity of the bell ringing. The reason is that when you ring a bell with a power greater than the ideal for this particular bell, the sound of the bell starts to distort.

To sum up, the ideal ring intensity is unique to each bell. By adjusting the power of the bell ringing mechanisms, we achieve the best acoustic performance possible without sacrificing volume or clarity of the bell’s tone. Additionally, another benefit of fine tuning the power of the bell ringing is avoiding straining the bell’s wall, thus protecting the bell from possible cracks.



The size of a bell dramatically affects the volume of sound it produces. A large enough bell can produce multiple decibels in intensity compared to a smaller one. As a result, the sound of a large bell can “cover” the sound of a smaller bell when rang together.

For the above reason, in the event that two or more bells that greatly differ in size, ring simultaneously, the difference in volume must be taken into account, and then be appropriately adjusted by the Bell Systems mechanisms in order to have the most acoustically pleasing result.



In many countries, the legislation regarding sound transmission and maximum noise levels in large urban centres and densely populated areas can be very restricting to temples, churches and town halls that are equipped with bells. A lot of times as a result bell ringing is prohibited.

In other cases, such as in churches near hospitals and nursing homes, a quieter bell ringing is desirable. Up until now, quitter bell ringing was not always easy to achieve even when ringing the bells manually.

In all the above cases, regardless of the size of the bells, ‘’Bell Systems’’ mechanisms can adjust precisely the impact intensity of bell ringing of each bell to the desired decibel levels (even when the required level is extremely low!).
