Front view sensor connection
Description
This 4-channel measuring amplifier for sensors with strain gauges is equipped with a USB
interface. The voltage is supplied via the USB port at the back of the measuring amplifier.
The measuring amplifier can be delivered with an SUB-D37 connection or with 4x M 2 ports.
The measuring amplifier has eight digital inputs and outputs.
On the backside SubD25 socket, strain gauge full-bridges and half-bridges 20 Ohm up to
kOhm as well as PT 000 temperature sensors and 000 Ohm single grid strain gages or
voltages 0 ... 5V can be connected.
The front-end M 2 socket is configured by default for strain gauge full-bridge connections
and for voltage inputs 0 ... 5V and 0 ... 0V.

.Remove both screw covers from the input side and remove the fastening screws from the
front cover.
2.The two hexagonal bolts on the 37-pin D-Sub port must be loosened using a socket
spanner (5 mm).

Wiring diagram for position sensors
The measuring amplifier GSV-4USB must be configured by the manufacturer separately
when using it with potentiometric position sensors (linear potentiometers or draw wire
displacement sensors) for the M 2 version.
The position sensor’s wiper is connected to the measuring amplifier’s “Aux” input (M 2) or
“UE“ (SubD37). The position sensor supplies via the sensor supply +Us and -Us.
5-pin port 37-pin D-SUB port
The potentiometric position sensor is supplied with 2.5 V.
The “Aux” input or UE records voltages of 0...5 V.

Strain Gage measuring amplifier GSV-4BT
Figer 5: GSv-4BT M12
Description
The measuring amplifier GSV-4BT is suited to wireless measurement data acquisition with
wire strain gauge sensors. The GSV-4BT is suitable for connecting Straingage full bridges
and half bridges. For quarter bridges ( 20 Ohm, 350 Ohm, and 000 Ohm), there is a
connection option in three-wire technology.
Data is transmitted by radio via the Bluetooth Standard 2.0+EDR with serial port profile
(SPP). The range is 20 m in buildings or up to 00 m when in direct line of sight. Commercial
Bluetooth dongles with Widcom or Toshiba drivers which support the “serial-port-protocol”
are suitable as receivers.
Data rates are possible from 0 Hz to 500 Hz. They are supplied via e.g. a lithium-polymer
battery. By opening the interface for the application software, the module is switched on.
Current consumption is less than 50 mA. When not in use, current consumption is under
0 mA.
A battery can be charged at 5V supply voltage via an integrated charge regulator. Threshold
values or digital outputs can be programmed with the 8 digital outputs
.
