XL403D PRELIMINARY [Patent Pending] Advanced Digital Accelerometer Built-in Analyses, Dynamic Interface, ±1 g to ±15 g • • • • • Built-in Analyses reduce the need for post-processing time and equipment, plus shrink data file sizes. Simply request minimum values, maximum values, peak-to-peak, magnitude, tilt, or threshold. Dynamic Customer Interface - Set and query the XL403D with SCPI-like commands such as CONFigure or MEASure. Users may select the scan rates needed and set threshold detection and actions as required. Employ start-up scripts and run multiple sensors with data synchronization. Flexible Output - Readouts at specified intervals can include one, two or three axes plus temperature. Choose engineering units (g, ° C), or raw ADC counts at RS232 or RS485 baud rates. High Accuracy and Linearity over Wide Temperature Range - Each sensor output is fully temperature compensated, improving accuracy by minimizing variations due to temperature and aging effects. Each axial sensor has been tested over the -40° to + 85°C temperature range. Built-in Calibration - Calibration data for each sensor is maintained in the accelerometer. All data output is fully calibrated in accordance with NIST standards. • Self-Test - Self-test signal and commands help verify channel • Rugged for Harsh Environments - The XL403D is robust • • • • integrity and wiring connections. and can be used in harsh environments. The unit will survive 5000 g powered or unpowered. Built-In Power Supply Regulation - Unregulated DC power from +8.5 to +36 Volts is all that is required to measure acceleration and temperature. Reverse power voltages of up to -80 V can be withstood indefinitely. Transients of +80 V for 550 ms compatible with MIL-STD-704A can be withstood with full operation. Small Size - Completely conditioned triaxial accelerometer in less than one cubic inch. Earth Friendly Design - Lead-free design makes the XL403D environmentally safe while Measurement Specialties’ assembly process ensures reliable functionality. Fully-potted electronics eliminates the possibility of tin whiskers-related failures. Three-Year Warranty - This Measurement Specialties digital accelerometer comes with a three-year factory warranty. *Technical Data subject to change without notice The XL403D is the first accelerometer to support SCPI-like commands, return data in engineering units, and work with an ASCII terminal emulator. It also performs basic functions such as evaluating minimum, maximum, magnitude, peak-to-peak, and tilt. The output is configurable by the customer - choose number of axes, units returned, bandwidth, sample rates, function specifics, and analysis results. The sensor also contains a temperature sensor, microcontroller, and analog outputs in a small, easy-to-install package. The microcontroller takes 10-bit samples and performs temperature compensation and additional functions as programmed for output via the RS-485 interface. Order the range option best suited for your application to measure from ±1 g to ±15 g, and set your own low pass filter for bandwidths from 1 to 800 Hz.

Each unique function is performed on the scan measurements, with results maintained internally within the sensor. MIN – tracks the minimum reading on each channel since the function was configured MAX – tracks the maximum reading on each channel since the function was configured MAG – calculates the magnitude of the vector sum of axes A1, A2 and A3 PTP – tracks the peak-to-peak value for each channel since the function was configured. This is equal to MAX – MIN for each channel TLT – calculates the 2-axis tilt angle for any 2 axes that are in scan TH1 – tracks channels readings against individual channel threshold values TH2 – tracks MAG or TLT values against a threshold OU1/OU2/OU3 – output functions that print the values of functions on a configurable periodic basis When the XL403D threshold function is set, external controls can be triggered when the threshold is reached. Receive a warning, flip a switch, apply a brake - take action immediately when limits are exceeded. XL403D Advanced Digital Accelerometer precisionsensors.meas-spec.com 2236 N.
