How is our DOT sensor different from traditional wired accelerometers?
Our DOT sensors leverage cutting-edge MEMS technology, offering several distinct advantages over conventional wired accelerometers:
- Measure from 0Hz: Unlike piezo-accelerometers, our sensors measure down to 0Hz, capturing the gravity component. This provides valuable insights into sensor orientation, which is crucial for detailed motion analysis. Our high accuracy 70ug/sqrt(Hz) sensor is among the premium solutions within the existing MEMS-technology, matching close to the superior accuracy of piezo-accelerometers.
- Ideal for Moving Parts: Cabling in fast-moving systems can be both dangerous and impractical. Cables are prone to getting caught in moving components, which could damage both the sensors and your equipment. Our DOT sensors eliminate this risk with their wireless design. Additionally, their lightweight and compact form factor ensures minimal mass loading, reducing any potential impact on machine behavior.
- Effortless Installation: Say goodbye to complex wiring and tedious setups. Our DOT sensors feature a simple plug-and-play installation. Just mount them to your structures easily with a double-sided tape, magnet or screws within minutes, you're collecting valuable data to improve your design. No lengthy preparations or complicated processes.
Why Do You Need One?
A wise person once said, "When you assemble your machine, the true physics reveal themselves."
As your machine comes together, small errors begin to accumulate. Parts may not align perfectly with your design, assembly misalignments can introduce extra friction, and the actual loads applied to your system may be quite different from what you initially anticipated. The result? Increased vibrations, annoying noise, and, in the worst case, a drop in performance.
By placing sensors on key components like your drivetrain or machine housing, you can pinpoint where these vibrations are originating and address the root cause. Whether you’re using machine learning algorithms or developing physics-based digital twins, accurate and reliable data is essential to guide you toward better performance and system optimization. Our DOT sensors provide that data, helping you understand and refine your machine’s operation.

Sensor Purpose, Applications & Accuracy
What is the application where the DOT sensor works best?
The DOT sensor is extremely light (under 10 grams) and compact, making it ideal for components with significant motion. It provides full high‑frequency time‑domain data (up to 16 kHz), enabling detailed vibration analysis beyond summary metrics or FFT outputs.
Is the DOT sensor accurate?
Yes. It offers selectable ranges from 2g to 16g with 16‑bit resolution and a low measurement noise of 70 µg/√Hz, suitable for most industrial vibration applications.
Mounting & Installation Flexibility
How do I mount the DOT sensors?
For frequencies below 1 kHz, double‑sided tape is sufficient. For stiffer coupling, magnets or epoxy are recommended. Dedicated mounting feet are also available.
Can I use the DOT sensor with a cable?
If you connect the DOT sensor with a USB-C cable, the sensor is continuously powered and has an infinite autonomy. The data transfer will still happen wirelessly.
Multiple Sensors, Synchronization & Data Handling
Can I use several DOT sensors concurrently?
Yes. Up to 6 sensors can perform tri‑axial measurements at 2 kHz. Higher sampling rates are possible with uni‑axial configurations.
How do you achieve synchronicity between the sensors?
Synchronization is achieved through hardware time‑stamping based on radio activity, allowing accurate alignment of events across sensors and the gateway.
Can I measure real-time vibration data?
No. Due to power‑saving buffering behavior, wireless sensors cannot stream true real‑time at high sampling rates. Expect transmission delays of a few hundred milliseconds—suitable for monitoring, not fast control.
Pricing, Alternatives & Product Decisions
How did you determine your pricing?
Pricing is benchmarked against comparable sensors in the market. FORCEBIT offers slightly lower pricing to support broader adoption as an innovative startup.
What if I find another product that appears better or cheaper?
Just contact us. If an alternative genuinely fits your application better, we will openly acknowledge it—and your feedback helps us improve.
Range, Sensor Types & Placement Guidance
Do you offer 6DOF IMU sensors?
Not currently. High‑range rotational MEMS typically lack the required bandwidth, range, and clock stability. We recommend using multiple linear accelerometers to estimate rotational motion.
What if I need a higher measurement range than 16g?
If the main vibration direction is known, the sensor can be mounted at an angle to effectively extend the measurable range. We chose not to use high‑range MEMS due to trade‑offs in bandwidth and accuracy.
How do I know where to place the sensors?
Optimal placement depends on system dynamics. A structural model can help; alternatively, our engineers can advise. Thanks to easy installation, you can quickly test multiple locations to identify the most informative positions.
