Vibra Tuning Fork vs. Monobloc

User scalewoodman recently asked us:

In what ways is the Vibra sensor superior to the MonoBloc?

This is a great question!

The Vibra® tuning fork sensor utilized in the Intelligent-Lab HT, AJ and SJ models is a unique method of obtaining the weight result in balances.

MonoBloc (Mettler Toledo), UniBloc (Shimadzu) and other varieties of one piece force technology are excellent devices for attaining the weight result from a balance. The questioner asks in what ways is the Vibra sensor superior?

The Vibra sensor is an elegant and unique engineering technology and what it can do for you. Firstly, the technology is very different. Developed in Japan in the 1980’s as the world’s first tuning fork sensor, the system utilizes a double-ended tuning fork, which, when force is applied, vibrates. The frequency at which it vibrates changes when the weight applied changes. This change is measured (in force or mass) by digital output processing.

The frequency generated by this system is extremely stable, giving high repeatability,  durability and excellent temperature resistance.

Several advantages come from this technology.

  1. The fact that the system is not sensitive to temperature means that balances fitted with a Vibra tuning fork sensor do not require a long warm up period. You can place the balance on a suitable weighing surface, connect the power, calibrate and use almost immediately.
  2. The Vibra sensor is extremely robust and therefore not susceptible to damage from the usual problems of shipping or poor handling.
  3. The Vibra unit consumes very little power, making it environmentally friendly and cost effective.
  4. The Vibra sensor is compact and light.
  5. Replacement of the Vibra sensor is relatively simple and quick.

Vibra Technology is uniquely versatile and can be used in many different weighing applications, from analytical balances, such as the HT 224-R and right up to the higher capacities of bench scales. Its simplicity makes it one of the most cost effective methods available today, providing the highest precision weighing results.
