Memsic Inertial Systems

MEMSIC’s inertial systems provide end-users and systems integrators with fully-qualified MEMS-based solutions for measurement of static and dynamic motion in a wide variety of challenging environments, including: avionics, remotely operated vehicles, agricultural and construction vehicles, automotive test and wind power turbines.

MEMSIC’s success in developing innovative sensor modules and integrated sensing systems is the result of its combined expertise and intellectual property in sensor characterization, MEMS sensor integration algorithms, and market-specific operational and performance requirements. In addition, MEMSIC’s inertial products are designed and tested to meet industry-standard and/or customer-specific environmental requirements, and many are approved for safety-critical applications by government agencies such as the Federal Aviation Authority (FAA).

MEMSIC’s stand-alone sensor modules include a selection of cost-effective single-axis and three-axis MEMS accelerometers (GP, TG) and single-axis and dual-axis MEMS tilt sensors (CXTA, CXTLA, CXTILT), all with signal-conditioned outputs and small and easy to mount environmental packaging.

MEMSIC also offers a family of three-axis magnetometers (CRM, CHS) that provide highly accurate sensing of local magnetic field through all orientations.

MEMSIC’s integrated sensing systems uniquely combine best-in-class MEMS accelerometers, MEMS (or FOG) gyroscopes, magnetometers and GPS technology, high-speed DSP and patented Kalman filter algorithms. MEMSIC’s integrated sensing solutions span a broad range supporting the needs for cost-effective entry-level inertial measurement units (IMU) through Vertical Gyros (VG) and high-end fully-integrated GPS-aided Attitude & Heading Reference Systems (AHRS/NAV).

Accelerometers

General vibration sensing applications often call for the use of rugged accelerometers that can offer flexibility in both measurement range and operation characteristics, while exhibiting proven accuracy in a variety of test setups. The ability to use the same sensors within multiple setups reduces instrumentation costs, while increasing efficiencies.

MEMSIC offers a range of MEMS accelerometers for general purpose vibration measurements. They are known for their exceptionally high measurement accuracy and outstanding overload and shock durability. With rugged sealed lightweight enclosures, these sensors may be used across multiple types of aerospace, automotive, R&D and test and measurement applications. High-precision variable capacitance accelerometers from MEMSIC, with their rugged designs, high output and wide dynamic measurement ranges, are ideal for vehicle dynamics, vibration monitoring systems and condition monitoring applications.

Magnetometers

Remote Magnetometers

The CRM Series remote magnetometers are high performance three-axis strap down magnetic field measurement systems. They are designed as a local magnetic field reference for use with high performance Attitude & Heading Reference Systems such as the MEMSIC AHRS500 or AHRS510.

Typical Applications:

Primary Flight Display Heading Reference, Unmanned Aerial Vehicle Control

Heading Sensors

The CHS series of high performance fully calibrated, small diameter heading sensors are specifically designed for towed sonar array and seismic streamer applications. The CHS heading sensor is based on a solid-state "strapdown" configuration that avoids the performance limitations of traditional floated compass systems and offers improved reliability. A 3-axis fluxgate magnetometer and 3-axis micromachined accelerometer are combined with digital signal processing electronics and fully integrated within a small diameter pressure rated housing.

Typical Applications:

Towed sonar arrays, Buoy Orientation, Magnetic Compassing

Tilt Sensors

Analog Tilt Sensors

The CXTA and CXTLA single and dual-axis tilt sensors offer an easy-to-use signal conditioned 0-5V analog output. With the CXTA, angle measurements can be made up to ±75 degrees in tilt range while the CXTLA offers high-resolution accuracy for measurement up to ±20 degrees. The zero-angle voltage and sensitivity are stable over the lifetime of the device. The sensor works with unregulated power supply inputs of 6 to 30 VDC and is available in plastic and high-temperature metal housing.

Typical Applications:

Crane Boom, Aerial Lift, Solar Panel Control, Platform Leveling

Digital Tilt Sensors

The CXTILT02 inclinometer offers outstanding resolution, dynamic response and accuracy. The CXTILT02 measures the tilt angle of an object with respect to the horizontal in a static environment. To measure tilt, also called roll and pitch, the sensor makes use of two micro-machined accelerometers, one oriented along the X-axis and one along the Y-axis.

Typical Applications:

Construction Equipment, Mining Equipment, Surveying
