Avery Weigh-Tronix BSQ Bench Scale Base Frequently Asked Questions

The Avery Weigh-Tronix BSQ is a highly accurate digital bench base with over 1 billion internal counts and a readability of over 3.5 million divisions (unapproved).

In practice, this means that the Avery Weigh-Tronix BSQ scale platform can detect even the tiniest of weight changes with astounding precision.

Featuring the very latest state of the art suspended Quartzell technology, the BSQ guarantees repeatable balance accuracy at all times. Small and large items can be weighed on a single base, allowing one scale to do a job that might previously have required several. With a fast return to zero between readings, the Avery Weigh-Tronix BSQ scale base provides the speed and repetitive accuracy that can be vital in situations where highly accurate weight readings are required.

When used with the ZM400 series indicators, the BSQ bench base can accurately display down to 0.01g, giving balance accuracy but with the strength required for use in an industrial environment.

We put together a list of the most common Frequently Asked Questions (FAQ) below.

What is Quartzell™?
Quartzell stands for Quartz Digital Transducer (QDT). It uses true digital signals from quartz crystals that are precisely mounted on an intricately machined aluminum frame. The device converts the oscillating frequencies from two crystals into a digital signal which is representative of the load applied. When profiled, the output signal provides an extremely accurate measurement with a higher resolution than normal strain
gauge technology.

What are the advantages of using Quartzell over Analog strain gauge load cells?
Unlike a strain gauge load cell, which produces an analog signal that has to be converted to digital, the Quartzell transducer utilizes the change in frequencies from two double-ended tuning-fork quartz crystal sensors to produce a true digital signal measured in frequency. This eliminates the need to convert an analog signal to digital and this significantly reduces errors, while increasing speed and accuracy of the measured

The digital signal allows a scale to weigh faster and with greater resolution. The Quartzell uses two quartz crystals, one in compression and the other in tension. This helps reduce
the impact of environmental influences, such as changes in temperature and pressure.

What is meant by Internal Resolution?
Internal resolution equates to the smallest internal count data bit that can be measured by the Quartzell. The BSQ base can produce over 1 billion internal counts. When compared to other Avery Weigh-Tronix products, this is a massive jump in performance and
accuracy. For example, see the chart below.
