BX3-HD44-CAN 3-Channel CANbus AND USB Strain Gage Amplifier
The BX3-HD44-CAN measuring amplifier is a 3-channel strain gauge amplifier with a CAN interface and USB port. Sensors with full-bridge strain gauges, e.g., 3A and 3AR, are connected via the front-panel 44-pin SubD44HD connector. An M12 socket and an M12 plug are available on the rear panel for connecting the CAN bus cable. The BX3-HD44-CAN measuring amplifier is powered via the CAN bus cable with 10 VDC to 28 VDC. As an alternative to the CAN bus, measurement data can be transmitted via the USB-C port. The 5 VDC power supply is then also provided via the USB interface. Measurement data can be recorded both via the integrated USB port via the CAN bus using the BlueDAQ software. The BlueDAQ software allows reading, recording, and visualizing measurement data. Multiple BX3 can be connected together via CAN and then connected to PC using a PCAN-USB converter. The BX3-HD44-CAN measuring amplifier is factory-configured for connection to quarter-bridge strain gauges with 120 Ohms, 350 Ohms, or 1 kOhms in three-wire technology.
