| [[ADI>EVAL-CN0533-EBZ]] is a MEMS accelerometer (ADXL1002) vibration sensing solution with included analog 4-20 mA current loop interface circuitry, suitable for Condition-based Monitoring (CbM) applications. 4-20 mA current loop has been an industry analog signaling standard since 1950s. The main advantage of this signal standard is that there exists virtually no attenuation over long cables, therefore more robustness in EMI prone environments, such as industrial and factory settings. This reference design enables utilization of high bandwidth, ultralow noise MEMS accelerometers on a legacy 4-20 mA data acquisition (DAQ) systems for CbM applications. | [[ADI>CN0533|EVAL-CN0533-EBZ]] is a MEMS accelerometer (ADXL1002) vibration sensing solution with included analog 4-20 mA current loop interface circuitry, suitable for Condition-based Monitoring (CbM) applications. 4-20 mA current loop has been an industry analog signaling standard since 1950s.

| The EVAL-CN0533-EBZ is very straightforward to setup. A cable, and an ICP signal conditioner (or an IEPE compatible DAQ, or a current source) are needed. For electrical setup: | The EVAL-CN0533-EBZ is very straightforward to setup. A cable, power supply (12-24 V), and a 4-20mA receiver are needed. For electrical setup: |
| * Solder a twin twisted wire, coaxial or shielded cable to the EVAL-CN0532-EBZ printed circuit board (PCB). Ground line to GND and supply/signal to ACC as shown in the figure below. Note: the output voltage increases if there is a positive acceleration in positive sensitivity axis direction. | * Solder a triple twisted wire or shielded cable to the EVAL-CN0533-EBZ printed circuit board (PCB). Ground line to GND, 4-20mA output current to IOUT, and 12V supply to VCC as shown in the figure below. |

| |
| * Connect the other end of the cable to an ICP Signal Conditioner (e.g. PCB 482C64), or an IEPE-compatible vibration measurement equipment such as the LMS SCADAS from Siemens or the CompactDAQ from National Instruments (note: in most IEPE compatible DAQ systems, the DC level of the output is eliminated through an AC coupling circuitry). Alternatively, one can use a current source, e.g. Keithley 6220, set the output current to 4 mA, and max voltage to 16 V. The voltage of the current source is the output, as shown in the picture below. Without an external acceleration, the IEPE output should be around 12 V. In this setup the DC level is not removed. | {{ :resources:eval:user-guides:circuits-from-the-lab:cn0533_pic.jpg?direct&250 |}} |

| {{ :resources:eval:user-guides:circuits-from-the-lab:cn0532_currentsource.png?direct&300 |}} | * Supply the EVAL-CN0533-EBZ with 12V, and connect the other end of the IOUT and GND cables to a 4-20 mA receiver such as National Instruments NI-9203. (Note: some 4-20 mA receivers have integrated voltage supply that can be used instead of an external 12V needed to power up EVAL-CN0533-EBZ). Alternatively, an accurate and temperature stable resistor along with a voltage DAQ system may also be used instead of a current DAQ. The resistance value should be according to the input voltage range of the DAQ. |

| * Set the acceleration sensitivity (40 mV/G) on the vibration measurement equipment from Step 4 to taking data with the accelerometer sensors. The sensitivity scale of the ADXL1002, therefore EVAL-CN0532-EBZ, may slightly vary from part to part. The ADXL1002 can be simply calibrated with gravity field or other reference sensors. | * Set the acceleration sensitivity to 128 µA/g on the DAQ or vibration measurement equipment (the sensitivity scale of the ADXL1002 may slightly vary from part to part, and the ADXL1002 can be simply calibrated with gravity field or other reference sensors). |
