加速度计MS800
The Colibrys MS8000 accelerometer has been designed and developed by Colibrys mainly to respond to
inertial and tilt sensing requirements even if in some cases, it can also be used for vibration sensing.
I t is largely used where advanced specification are required (Instrumentation), under harsh environments (MilAerospace and Geophysics), and for a wide range of general applications (Industrial, Transportation or Civilian). The main advantages of this motion sensor are the long term bias stability, the low and qualified vibration rectification error, the low temperature coefficient even without compensation and the low power.
This product has passed extensive qualifications and is successfully incorporated in IMU or AHRS for
MilAerospace and Land Navigation applications where reliability and long term compliance to specifications are

very severe. Standard MS8000 products are available with a full-scale range of ±2g, ±10g, ±30g and ±100g (Table 1) but Colibrys has the experience and flexibility to offer a wide range of custom products upon request. Colibrys offers the capability to customize the performance such as shock resistance, vibration rectification error as well as the full-scale range of the products, which can vary from ± 1g to more than ± 100g.
Product description
The MS8000 product is a MEMS capacitive accelerometer based on a bulk micro-machined silicon element,
a low power ASIC for signal conditioning, a micro-controller for storage of compensation values and
a temperature sensor (Fig. 1). The MS8000 is operating from a single power supply voltage (between 2.5V
and 5.5V) with a low current consumption (< 0.5mA at 5V). The output is a ratiometric analog voltage that
varies between 0.5V and 4.5V for the full-scale acceleration range at a voltage supply of 5V. The sensor
is fully self-contained and packaged in a 48-pin LCC ceramic housing, thus insuring a full hermeticity.
It operates over a temperature range of –55°C to 125°C and can withstand shocks up to 6000g without
performance degradation. Long-term stability of bias and scale factor are typically less than 0.1% of
full-scale range. For the ±2g version (MS8002.D), bias temperature coefficient is typically 100 μg/°C
and scale factor temperature coefficient 100 ppm/°C without external compensation± 30g ± 100g
