The measuring amplifier BSC4D-BT is suited to wireless measurement data acquisition with wire strain gage sensors and is also suitable for connecting strain gage full bridges and half bridges. For quarter bridges (120 Ohm, 350 Ohm, and 1000 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-meters in buildings or up to 100 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 up to 450 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 150 mA. When not in use, current consumption is under 10 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 4 digital inputs/outputs.
