Frequently Asked Questions

A quick guide to our most popular gyroscope and accelerometer questions.

General

InnaLabs® is a leading manufacturer of high-performance inertial sensors, including Tactical grade Coriolis Vibratory Gyroscopes and Navigation grade, Quartz Servo Accelerometers. InnaLabs® offers solutions for the Aerospace, Subsea, Marine, Space, Energy, Industrial, Civil Engineering, and Transportation markets.

Accelerometers

Our AI-Q-2010 accelerometer offer navigation grade performance with excellent reliability and fast delivery
The AI-Q-710 accelerometer offers performance between tactical and navigation grade at cost competitive prices.
We can guide you in the choice of the correct accelerometer for your application. You can choose between AI-Q-710, AI-Q-1410, and AI-Q-2010 depending on the desired measurement range, bias and scale factor composite repeatability and temperature sensitivity requirements. AI-Q-710 has a smaller casing which is suitable for applications driven by volume constraints.
Our products have been developed to meet the moderate to high performance requirements of our customers. They have low output errors, low intrinsic noise, and very high bias and scale factor repeatability. They are built in Europe, offer excellent low term stability and are ITAR free. Their performance is supported with exceptional delivery times and very competitive pricing.

The external resistor used affects the maximum g-range measurable by the test system, due to voltage drop across both it and the internal coil resistance.

As the input voltage is increased, a larger voltage drop is available, enabling the same acceleration level to be measured with a larger measurement resistor, thus improving the signal-to-noise ratio.

Gyroscopes

InnaLabs® currently offer 1 and 2 axes gyros, with either analog or digital output. The gyros can be shipped either within a casing or with separated sensitive elements and electronics box. Finally two different performance ranges are available.
Yes it is. We can change physical configuration, mechanical and electrical interface, as well as customize performance according to customer requests.
The material of the InnaLabs gyroscope housing is aluminium. The user should preferably use an aluminium base plate and dowel for mounting.
Input rates limits are ≤110°/s for analogue gyros and ≤160°/s for digital ones. The gyroscope cannot be damaged when the input rate exceeds the input rate limits. Once the input rate comes back within the limits, the recovery time to get a functional output with full performances is less than 3 sec.
The InnaLabs gyroscope achieves full performance within the first 10 minutes after start-up (bias and scale factor). Over the first 10 min, at room temperature, the gyroscope bias error can drift by 15 °/hr, with a typical value of 3 °/hr peak.
The InnaLabs gyroscope outputs are within 5% of the input rate, at an input rate of ±110 °/s within 2 sec after power on (typical 1 sec).
Yes, the InnaLabs gyroscope’s power supply board is protected against short circuits, so any output can be short circuited without damage.
The InnaLabs gyroscope’s power supply board is protected against reverse polarity up to 25 V.
Bandwidth is the frequency range in which the accelerometer or gyroscope operates. The gyroscope operates from DC (zero frequency) to some upper frequency (typically defined by the frequency in which the frequency response function magnitude is down by 3 dB). The InnaLabs coriolis vibratory gyroscope is capable of detecting rates with ‐3 dB bandwidth when considering frequencies ≥300 Hz.
The InnaLabs coriolis vibratory gyroscopes are fully protected against corrosion thanks to a hard anodized surface treatment. The gyroscopes are tolerant to 50°C combined with 95% humidity.
The operating pressure is ranging from 90 hPa to 1110 hPa.
The non-operating temperature range is -55 °C + 90 °C. The maximum thermal slope is ± 10 °C/min.
The operating temperature range is -40 °C +85 °C. The maximum thermal slope is ± 2 °C/min on the Gyro Unit mounting plan.
The life time of the InnaLabs coriolis vibratory gyroscopes is more than 17 years.
