LABORATORY APPLICATIONS

The primary use of Quartzdyne Series DS Transducers in laboratories is for calibrating other downhole transducers and strain gauge / piezoresistive sensors.

Quartzdyne Series DS transducers are used as "in-house pressure standards" for calibrating process transducers. They are also used for a few single point measurements of critical process parameters.

Two Quartzdyne transducers can be used for high stability differential pressure measurement. A common application is measuring the pressure drop across a rock sample in a laboratory measurement of permeability. There are lower cost differential pressure transducers which are more commonly used to measure permeability, but it is easy to demonstrate the cost effectiveness of more accurate measurements. (While most of the permeability measurements use Series DS transducers, some test designs have required higher temperature transducers.)

Where necessary, Series DS transducers can be locally certified to better performance levels than the Quartzdyne calibrations. Some units have been certified (by NAMAS in the UK) to 0.01% of reading over the range of 10% FS to 90% FS. These transducers are certified for use as transfer standards for calibrating (0.03% FS) dead-weight testers.
