Strain Gage measuring amplifier GSV-4B
Description
The measu ing amplifie GSV-4BT is suited to wi eless measu ement data acquisition with
wi e st ain gauge senso s. The GSV-4BT is suitable fo connecting DMS full b idges and
half b idges. Fo qua te b idges (120 Ohm, 350 Ohm, and 1000 Ohm), the e is a
connection option in th ee-wi e technology.
Data is t ansmitted by adio via the Bluetooth Standa d 2.0+EDR with se ial po t p ofile
(SPP). The ange is 20 m in buildings o up to 100 m when in di ect line of sight.
Comme cial Bluetooth dongles with Widcom o Toshiba d ive s which suppo t the “se ial-
po t-p otocol” a e suitable as eceive s.
Data ates a e possible f om 0 Hz to 125 Hz. They a e supplied via e.g. a lithium-polyme
batte y. By opening the inte face fo the application softwa e, the module is switched on.
Cu ent consumption is less than 150 mA. When not in use, cu ent consumption is unde
10 mA.
A batte y can be cha ged at 5V supply voltage via an integ ated cha ge egulato .
Th eshold values o digital outputs can be p og ammed with the 8 digital outputs
.
