C o So mi on ng DMU30 High Performance MEMS HPIM MU) Inertial Measurement Unit (HPIMU) Description y DMU30 is the first of a new family of High Performance MEMS IMUs (HPIMU) incorporating precision VSG3QMAX high-Q inductive resonating ring gyroscopes and capacitive accelerometers. im Key features in ar DMU30 is a six-degree-of-freedom inertial measurement unit providing precise 3-axis outputs of angular rate and acceleration, delta angle and velocity, and temperature, at 200Hz. Pr el • Precision 6-DOF MEMS Inertial Measurement Unit • Silicon Sensing’s latest VSG3QMAX inductive gyro and capacitive MEMS accelerometer • Excellent Bias Instability and Random Walk Angular - 0.2°/hr, 0.02°/hr Linear - 30μg, 0.05m/s/hr • Non-ITAR • Compact and lightweight - 68 x 61 x 62h (mm), 300g • Internal power conditioning to accept 4.75V to 36V input voltage • RS422 interfaces • -40°C to +85°C operating temperature range • Sealed aluminium housing • RoHS compliant • In-house manufacture from MEMS fabrication to IMU calibration • Evaluation kit and integration resources available • First class customer technical support • Future developments and expansion capability, e.g. magnetometer, barometer, GPS DMU30 represents a realistic, alternative to established FOG/RLG based IMUs due to its exceptional bias stability and low noise characteristics, yet it is comparatively compact, lightweight and offers low cost of ownership. Designed specifically to meet the growing demand from high-end commercial and industrial market applications for a ‘tactical’ grade non-ITAR IMU, DMU30 utilises Silicon Sensing’s class leading MEMS inertial sensors integrated and calibrated using an in-house state-ofthe-art test facility. Applications • Hydrographic surveying • Airborne survey and mapping • INS (Inertial Navigation Systems) • AHRS (Attitude and Heading Reference System) • GPS drop-out aiding • Maritime guidance and control • GNSS (Global Navigation Satellite System) • Autonomous vehicle control and ROVs • Machine control • MEMS alternative to FOG/RLG IMUs © Silicon Sensing is an Atlantic Inertial Systems, Sumitomo Precision Products joint venture company DMU30 High Performance MEMS Inertial Measurement Unit DMU30 4.75 to 36V 14 62 Regulators Power Return 15 Expansion Feature 61 Run Mode Sync Prog Reset Chassis GND 4 3 2 1 13 12 11 10 9 All dimensions in millimetres Parameter MPU PU MOSI MISO Bias instability Random walk Bias over temp Noise (rms to 100Hz) Pr Accelerometer Properties el Scale factor over temp SF non-linearity Rx_Lo 7 TX_Lo 8 TX_Hi <0.2º/h 9 Chassis GND <0.02º/√h 13 Run Mode 14 4.75 to 36V 15 GND (Power Return) 10 Reset ±20º/h 11 Prog (Factory Use) 0.15º/s For full technical datasheets please visit: www.siliconsensing.com ±10g Random walk <0.05m/s/√h ±1.5mg 1mg Cross Axis Sensitivity ±0.35% Temperature Sensor Properties -45 to 100ºC ±3.0ºC IMU Properties -40 to 85ºC Start-up-time <1.0s Power <3W Supply voltage RS422 ±100ppm ±100p <0.03mg Operating temperature 12 Sync ±100ppm Bias instability Accuracy at temperature High Performance Gyro Z Pin Rx_Hi ±100ppm Range Accelerometer (-X, -Y) Pin 6 SF non-linearity (±10g) Over temperature High Performance Gyro Y Pin Connections 5 ±100ppm Noise (rms to 100Hz) Accelerometer (+X, +Z) Temperature T e emp S Sensors ±200º/s 200º/ Scale factor over temp Bias over temp High Performance Gyro X Vref im Dynamic range Accelerometer (+Y, -Z) SS Specifi ecification Gyroscope Properties Dynamic range SCLK in Typical Data Analogue to Digital Converters RS422 Driver y 68 8 7 6 5 ar Tx_Hi Tx_Lo Rx_Lo Rx_Hi 4.75 to 36V Silicon Sensing Systems Limited Registered in England & Wales No. 3635234 Clittaford Road, Southway, Plymouth, Devon PL6 6DE The device mark Silicon Sensing is a registered trade mark of Silicon Sensing Systems Community Trade Mark 003587664 Silicon Sensing Systems Limited Clittaford Road, Southway, Plymouth, Devon PL6 6DE United Kingdom T +44 (0)1752 723330 F +44 (0)1752 723331 E [email protected] W siliconsensing.com Silicon Sensing Systems Japan Limited 1-10 Fuso-Cho, Amagasaki, Hyogo 6600891, Japan T +81 (0)6 6489 5868 F +81 (0)6 6489 5919 E [email protected] W siliconsensing.com Specification subject to change without notice. © Copyright 2015 Silicon Sensing Systems Limited All rights reserved.
