It can only measure one channel at a time, thanks to its integrated multiplexer it can sweep between the measurement channels. Due to the multiplexer setting time, the sampling rate is not exactly divided by 2. This BeanDevice is designed to work with PT100 and thermocouple sensors, it can output excitation current for the PT100, and voltage for the Thermocouple. This BeanDevice works with 4 types of sensor : Analog sensor with voltage output Three-wire RTD with hardware compensation Four-wire RTD Thermocouple Application with RTD-Based Cold Junction Compensation Please consider the environnement before printing this document.

31 BeanDevice AVX-DAQ-IEPE General description This BaanDevice AVX DAQ-IEPE is designed to be used for dynamic measurement (such as Accelerometers, force transducers and current loop sensors, and microphones). It can measure each channel at the same time. This Synchronous BanDevice is compliant with IEEE smart sensors, this technology is called TEDS (Transducer Electronic Data Sheet) and provide directly to the AFE data about the sensor (such as sensor type, output range, mapping method used, and calibration data). In that case, the end-user doesn t need to provide these information, this avoid error from human mistakes TEDS information configuration One-wire protocol is used to provide TEDS information between the sensor and the AFE. The sensor wiring is a little bit different: the digital part must be wired to a dedicated input (see TEDS Wiring Code), thus the maximum sensors available is limited to ma sensor configuration The standard 4-20 ma defines a constant voltage powered current loop where the information transmitted via the sensor consumption; the range is defined between 4 and 20 mill amperes. This configuration allows using long length of wire for connecting the sensors and the AFE and is less subject to perturbation. This design need a power supply to provide current to the sensor, we are using an external power supply as the voltage can go up to 24Volts Low Power IEPE sensor configuration IEPE (ICP) sensors uses a constant current power source, they varies their consumption resulting in a change in voltage. Normal IEPE sensors works on power supply up to 12 Volts or 24 Volts, low power version exists, these sensors works on 6 Volts and draws less power Analog sensor configuration The BeanDevice can work with standard analog sensors (resistive bridges, resistive divider ) Power Supply The BeanDevice can provide different mode of powering sensors, this depends of the sensor type, and a constant voltage / current can power the sensor Constant-voltage excitation The constant voltage output can be turned on which output a precise 5V (+/- 0.2%) and up to 155 ma in total. This voltage is also used as a reference for the ADC. Any change in the voltage will not be visible by the ADC. (The measurement is ratiometric to the reference) Please consider the environnement before printing this document. Page : 31 / 77

32 Constant-current excitation The constant current output can be turned on which output a precise current set by the AFE via a Digital to Analog converter that limit the maximum output current. We are using a 12 Bit DAC to set the maximum current, this DAC is referenced to the 5V reference, so each step is equals to: V step = 5 = mv This step is used by an Operational amplifier to set the current, with a shunt resistor of 47 Ohms The Current for each step is equals to: I step = V step = µa The range of current available is [0 ; [ ma by a 25.97µA steps. The maximum voltage is 5V. Please consider the environnement before printing this document. Page : 32 / 77
