QRS14 Single-Axis Analog Gyroscope

Product catalog summary

Overview: The QRS14 is a compact, rugged, solid-state inertial sensor designed for precision industrial applications such as platform stabilization, short-term navigation, GPS augmentation, camera stabilization, instrumentation, ride control stabilization, and wind turbine control.

Key Performance Features: The sensor is solid-state, compact, lightweight, operates over a wide temperature range, and features DC input/high-level DC output, internal power regulation, high reliability, and shock resistance.

Specifications: The QRS14 is available in two versions: a +12 Vdc version with a +1.0 to +4.0 Vdc output and a ±15 Vdc version with a ±5 Vdc output. It supports standard ranges of ±50, 100, 200, 500°/sec and has a full-scale output of +1.0 Vdc (-FS) to +4.0 Vdc (+FS) or ±5 Vdc. The scale factor calibration at 22°C is ±2% of value, with a deviation over temperature of ≤0.06%/°C. Bias calibration at 22°C is +2.5 ±0.045 Vdc or 0.0 ±0.075 Vdc, with a bias variation over temperature of <3.0°/sec.

Performance: The sensor exhibits short-term bias stability of <0.05°/sec and long-term bias stability of ≤1.0°/sec. G sensitivity is ≤0.06°/sec/g, with a start-up time of <2.0 sec and a bandwidth of >50 Hz. Non-linearity is ≤0.05% of full range, with a threshold/resolution of ≤0.004°/sec and output noise of ≤0.05°/sec/√Hz or ≤0.02°/sec/√Hz.

Environmental Conditions: The operating temperature range is -40°C to +85°C, with a storage temperature range of -55°C to +100°C. The sensor can withstand vibration operating conditions of 5 grms from 20 Hz to 2 kHz random and vibration survival conditions of 10 grms for 5 minutes per axis. It is shock resistant up to 200g in any axis and weighs ≤50 grams.

Pin Assignments: The QRS14-00XXX-102 and QRS14-00XXX-103 have different pin assignments for power and signal ground, Vdc input, rate output, and built-in-test activation. The built-in-test is activated by grounding Pin 7, causing an increase in rate output of 0.5 Vdc or 1.0 Vdc nominal.

Additional Information: The sensor is supplied with a mating connector and has specific dimensions and mounting instructions. For more details, users are advised to refer to the user’s guide regarding vibration tolerance and sensitivity.
