Unrivalled Accuracy
The BSQ is a highly accurate digital bench base with over 1 billion internal counts and a readability of over 3.5 million divisions. In practice, this means that the BSQ 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 scales. With a fast return to zero between readings, the BSQ provides the speed and repetitive accuracy that can be vital in situations where highly accurate weight readings are required. When used with Avery Weigh-Tronix ZM400 series weight 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.

Quartzell or QDT stands for Quartz Digital Transducer. 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 signal. 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.

Below we mention 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 our current products, this is a massive jump in performance and accuracy. See below for comparison.

Interference
The clam-shell cover is fully enclosed, reducing the likelihood of environmental interference caused by the accumulation of dust and dirt or even drafts which might otherwise cause slight nuances in weighing accuracy.

Fluids and Dirt
Built-in drip pathways help to channel unwanted dirt and fluids away from critical areas within the base. This clever design makes the scale suitable for use in dirty, oily environments where liquids such as cutting fluids could otherwise affect the accuracy of the weighing element.

Thermal Resistance
The internal design of the scale offers an excellent thermal coupling barrier, enabling weighing of hot items while protecting against a thermal shift that could affect the accuracy of the base.

Strength by Design
BSQ bench scale bases, available from Central Carolina Scale, are exceptionally rugged by design. These tough and resilient bases are engineered to resist over-loading and sudden dropped loads, with up to 1100% overload protection as standard.

The rugged die-cast clam-shell case and anti-shock spring suspension system protects the Quartzell weight sensor from sudden impacts and over-loads. This design and construction technique allows the scale to withstand overloads of more than ten times its capacity, without affecting accuracy. Designed for use in tough industrial environments, the BSQ is versatile enough for use in laboratories and other applications that require precision weighing.

Connectivity
Link the BSQ with a weight indicator or computer to facilitate capture and display of weight data. Avery Weigh-Tronix offers a vast array of compatible peripherals, from simple weight displays to more advanced programmable indicators. Peripherals link with the scale via RS232 or USB ports. The ability to power the base via either of these ports provides additional flexibility when weighing remotely.

One thing to consider with this base is the actual readability. Readability is the maximum recommended stable weight reading the scale can be expected to work at. Depending upon the environment that it is being used in, the new BSQ digital Quartzell base offers a readability resolution of around 3.5 million divisions. More resolution can be achieved if used in laboratory type environments. Now regarding NTEP approval trade verified - the base is NTEP, Measurement Canada and OIML approved to 10,000 division accuracy with up to 3 multi-range steps each allowing 10,000 divisions per range.
