BX8-AS BlueDAQ Series Data Acquisition System with Industrial Enclosure
The pricing listed on our website is only for U.S. buyers and all pricing is subject to change without notice. Any inquiries for products from buyers outside of the U.S. will receive a quote and availability from the licensed distributor nearest your region. These prices will be based on product availability, currency conversions, markets, taxes, shipping costs, as well as local support.
Model BX8-AS BlueDAQ Series Data Acquisition System with Industrial Enclosure is the newest addition to Interface’s family of measurement systems. Easy enough for the inexperienced user but powerful enough for the sophisticated test engineer, with the BX8 anyone can be up and measuring in minutes. Designed specifically for use with mV/V output sensors such as force, torque and pressure along with PT1000 thermocouples, and ±10V output sensors, the BX8 puts graphing, logging and display capabilities at a user’s fingertips. The BX8 also includes 1/4 and 1/2 bridge completion for seamless integration of strain gage measurements. Eight independent, user configurable, 16-bit scalable analog outputs can be connected to external devices.
The BX8 is ideally suited for use with 6-axis sensors requiring axis load calculations. The sensor coefficient matrix can be loaded internally into the BX8 via software interface and the outputs are actively scaled according to the calculations. All channels are sampled simultaneously and fully synchronized. When purchased with a 6-axis sensor, the system will arrive pre-configured and ready to use.
The BX8 is ideally suited for use with 6-axis sensors requiring axis load calculations.

Connection of thermocouple type K
The + wire of the temperature sensor type K is connected to the +Ud input of one of the analog input channels 1 to 7, the – wire to -Ud.
To measure the absolute temperature with thermocouple K, a PT1000 reference sensor is required, which must be connected to input channel 8.
It should have the same temperature as the type K sensor connector (cold junction compensation). Relative measurement is also possible with type K; in this case you do not need a reference sensor.
Connection of the active sensors
The single-ended voltage signal of active sensors is applied to Ue and GNDE.
Potentiometric sensors can be supplied via +Us. The energy supply for active sensors can be via galvanic isolated voltage VCCIO and GNDIO.
Connection of the TEDS cables for sensors with Transducer Elec. Data sheet
The 1-wire EEPROM memory module located in the sensor or in the sensor connector is connected with two wires: the ground of the EEPROM to GNDE and the signal cable (corresponding to its 3.3V supply cable) at the TEDS connector.
However, TEDS are supported only from firmware version 1.32 on and hardware version 4.0, which are devices that were purchased from about 11/2016.
