MMR,
I received another reply from the company today. He had an attachment and said the following:
Please find attached information about effect of overcurrent.
It is listed on lower half of the page.
Please note that the figure on the right
is current value at the burnout of gauge sensing element.
Excitation voltage depends on the gauge length of strain gauge.
For example)
If the current is 30 mA and resistance is 120 ohm, bridge voltage will be 7.2V*.
120 ohm x 0.03 A x 2 = 7.2 V

Let me know if you need anything additional.
