Digital Gauge Frequently Asked Questions
Question number FAQ-0116
What are the differences between the GS-1700 and GS-1800 series and the GS-1700A and GS-1800A series?
I am using the GS-1700, GS-1800, GS-4700, GS-4800, GS-6700, and GS-6800 series.
I would like to purchase the same item, but in the catalog and on the website, the model numbers have changed to
GS-1700A, GS-1800A, GS-4700A, GS-4800A, GS-6700A, GS-6800A series.
What is the difference between items with an 'A' in the model number and those without an 'A'?
"A" absent …The electrical circuit inside the sensor is at 0 V and the shield (housing) is in a short-circuit state.
With "A" …the electrical circuit inside the sensor is at 0 V and the shield (housing) is in a insulated state.
There are no changes to the mechanical properties or dimensions.
Using "A" with no alternative will not cause any issues when using "A" with it.
GS-1700, GS-1800, GS-4700, GS-4800, GS-6700, GS-6800 series
GS-1700A, GS-1800A, GS-4700A, GS-4800A, GS-6700A, GS-6800A series
* The GS-3800 series is currently (2019/01) the "B" version.
(GS-3813B, GS-3830B)
GS-3800 → GS-3800AChange from limited stroke method to unlimited stroke method in the bearings used in the bearing system.
GS3800A → GS-3800B
Change the relationship between the internal electrical circuit and the shield (enclosure) from a short-circuit state to an insulated state.
