Angular Sensor MTRS-614

This sensors is essentially an integrated assemble of our rate sensors and a MEMS gyro. The resulting instrument has low noise and could be used in LOC and platform stabilisation applications that require low noise, but do not have high requirements to bias. The sensor is the ultra small and lightweight rate sensor assembly. The sensors are characterized by high sensitivity and very low intrinsic noise level. The sensor is available in two versions. The MTRS614B is optimized to achieve low self noise, while the MTRS614A has lower g-sensitivity and consequently can deliver better performance where vibration is a factor in conditions.

Evalauation prototypes are available for immediate delivery.

Features:

  • Low intrinsic noise
  • Small dimensions and low weight
  • Electronics could be placed separately
  • Low power consumption
  • High sensitivity


Applications:

  • Stabilization Systems
  • Line of Sight Control
  • Robotics
  • Intelligent Safety Systems
