CRS03
Angular Rate Sensor
A robust and affordable mass-produced gyroscope for
automotive and commercial customers.
Angular rate sensors are used wherever rate of turn sensing is
required without a fixed point of reference. The sensor will
output a DC voltage proportional to the rate of turn and input
voltage.
High performance motion sensing even under severe shock and
vibration.
Whatever your application, the unique silicon ring technology,
coupled with closed loop electronics, gives advanced and
stable performance over time and temperature, overcoming the
mount sensitivity problems experienced with simple beam or
tuning fork based sensors.
Key Features
• Three model types available
• Excellent performance over temperature
• Repeatable drift characteristic
• High shock and vibration operation
• High reliability
• Metalised housing
