Sierra Instruments product story
Edited by the Engineeringtalk editorial team
Mar 1, 2005
Portable low-maintenance primary standard gas flow calibrators operate in the 5cm3/min to 50 litre/min flow range.
Sierra Instruments has developed a new line of portable low-maintenance primary standard gas flow calibrators, the Cal=Trak SL-500 and Cal=Trak SL-800.
Sierra, one of world's most preferred gas flow meter manufacturers, presents the long awaited successors to its well-known but discontinued Cal=Bench line of primary standard piston provers of the1990s.
The Cal=Trak SL-500 offers an excellent accuracy of +/-0.4% of reading, whereas the Cal=Trak SL-800 offers the best accuracy of any commercially available standard at +/-0.15% of reading.
Sierra customers use Cal=Trak in the manufacture, inspection, validation and recalibration of mass flow controllers, mass flow meters and numerous other varieties of gas flow measurement and control instrumentation.
Cal=Trak operates in the 5cm3/min to 50 litre/min flow range.
The broad turndown ratio allows three interchangeable flow cells to cover the entire range.
Alternatively, the modular nature of the Cal=Trak allows the user to begin with one flow cell and then add other cells as resources allow-creating the need for only a minimal initial investment from the customer to get started.
Sierra's Cal=Trak line provides primary NIST traceability, is manufactured under strict ISO17025 certification and is CE approved.
The dimensionally based primary accuracy of Cal=Trak is superior to pressure-based secondary methods and is backed by a rigorous uncertainty analysis.
Both Cal=Trak models offer data logging, digital communications, interval operation and many other productivity-enhancing features.
Fast enough to use as a flow meter, Cal=Trak is automatic and requires minimal training to get started.
It is well-suited for applications in the metrology, semiconductor, analytical, medical and pharmaceutical fields, among many others.
