15203B /25203B /35203B Accelerometer Digital Accelerometers User Configurable 1 to 15 g Digital Accelerometer These Measurement Specialties digital accelerometers are complete, easy-to-use, userconfigurable sensors containing one to three accelerometers, a temperature sensor, signal processor, RS-485 interface and three analog outputs in a small, easy-to-install package. No data acquisition system is required; data is streamed directly to a PC. A connection kit is available to set up and begin testing immediately upon receipt of the sensor. dimensions The analog/digital output range and low-pass filter of each digital accelerometer axis can be set via a built-in RS-485 interface using a free, downloadable Instrument Configuration Utility (ICU). An RS-485 to RS-232 adapter is available. Calibrated, ranged and filtered data can be streamed out at up to 3 Mbit/ sec via RS-485. Analog output of up to three calibrated, ranged and filtered channels are provided for compatibility with existing systems. Two through holes and four 3 mm x 0.5 mm threaded holes are provided for mounting.
