GSV-6L
Description
The measurement am lifier GSV-6L adds a configurable analogue out ut to the GSV-
6CPU. The GSV-6L is designed to be built into sensors and fits into the most confined
housing enclosures, such as connector housings of the "GSV-6K” ty e.
Even after it is enclosed, there is com lete sco e to configure all the ro erties of the
GSV-6L via two "Tare" and "Scale" control cables.
The calibration data from the electronic data sheet of the sensor is automatically acce ted
via a TEDS in ut. The analogue out ut is then automatically adjusted to the increase set in
TEDS. Dimensions and terminal assignment

Exam le: an offset of 50% with an analogue out ut 0...10V shifts
the zero oint at 0 mV/V to 5V. With an out ut of 4...20mA, the
zero oint is shifted to 12mA with an offset of 50%. The in ut
sensitivity is shown at all times on the remaining "End Value -
Offset" area.

The smallest data frequency at the out ut is 10Hz. At levels below
10Hz, a second-order IIR filter is used.

0.1, 0.2, 0.3, 0.4, 0.5, 1, 2, 3, 4, 5, 8 (high-res. mode)
In high-res. mode the hysical measuring range is restricted,
which means there is less "reserve" available for a zero
adjustment with the Tare function.
Available hysical measuring ranges: 8 mV/V, 4 mV/V, 2 mV/V, 1
mV/V
The in ut sensitivity can also be set to 5-digit recision using the
Tare and Scale cables in the ClickRClackR menu ("seamless").
Adjust autoscale level The autoscale level allows the out ut signal to be defined as a %
of the end value, which is shown by im lementing "Scale" with the
current weight limit. Default setting: 100% (a weight limit of 100%
is ex ected).
The autoscale level can be adjusted in stages, from 5% within the
range 0 to 100%. When "0%" is set, the autoscale function is

The switch-off threshold of the threshold value indicator can be

GSV-6K
Description
The measurement am lifier GSV-6K includes a strain gauge in ut via a 5- in M12 casing
bushing and an analogue out ut via a 5- in M12 housing connector.
The GSV-6K is used to convert the bridge signal from force, torque or strain sensors to an
analogue out ut signal.
The electronic data sheet of the sensor can be read via a TEDS interface. The
measurement am lifier scales the out ut signal to the end value of the set out ut signal
using the TEDS interface.
The out ut signal can be set as a voltage out ut or current out ut.
The out uts 0...10V, ±10V, 0...5V, ±5V, 4...20mA, 0...20mA can be set using the "Tare" and
"Scale" control cables.
Similarly, an offset or sam ling frequency can also be set.
