4-channel strain gage measuring amplifier BSC4A
Description
The measuring amplifier BSC4A is a measuring amplifier with 4 independent channels for
sensors with strain gages such as force sensors, torque sensors, acceleration sensors or
extension sensors.
This measuring amplifier is also suitable for connecting strain gage full and half bridges
from 87.5 ohm to 5000 ohm and strain gage quarter bridges with 350-ohm.
The measuring amplifier BSC4A is supplied with a plug-in 18V power supply and SUB-D
mating
plugs.
The voltage and current outputs are at the 15-pin Sub-D socket and one ground for each
analog output. Both outputs have been calibrated and can be used at the same time.
The sensor inputs, bridge competitions and the inputs for automatic zero adjustment of the
individual channels are at the 37-pin Sub-D socket.
The bridge completion resistance with 0.1% tolerance for 350-ohm strain gage is
maintained. The quarter or half bridge mode can be set by the customer at the 37-pin Sub-D
socket (see
wiring diagram for 37-pin Sub-D socket
).
As an option, it is possible to use the 6-wire technology. The use of 6-wire
technology must be
configured to the circuit board so this is a separate request that must be made at time of
purchase.
