How does the Wireless Vibration Sensor work?
Gateway and Kappa X technical specifications
Sensoteq’s proprietary wireless technology utilises a sub 1GHz channel to transmit data, this ensures that existing wireless technology such as Bluetooth or WiFi (2.4GHz) is not impacted. Our wireless channel has been designed to achieve maximum range in industrial environments, where large metal and concrete structures are commonplace.
- Standard Resolution Waveform & Spectrum @ 10kHz (every 24 hours)
- Measurement with Configurable Options (sampling window / frequency / resolution)
- RMS Velocity, RMS Acceleration & Peak to Peak (every minute)
- Temperature (every minute)
- 10kHz FMax
- 64G Peak Vibration
- IP69K Ingress Protection
- 5 Year Battery (User Replaceable)
- Hazardous Area rating
- 10kHz FMax (Daily Waveforms, Envelope spectrum)
Kappa X captures a time waveform at a sample frequency of 25.6kHz. This resolves to a 10kHz FMAX (maximum frequency) for analysis at 6400 LOR (Lines of Resolution). This is ideal for vibration analysis of industrial machinery, covering any applications running from nominal to very high speeds, such as gearboxes. It is possible to envelope the signal using Sensoteq’s Analytix platform to provide an unparalleled level of diagnostic capability in a wireless sensor
- Smart Wake (Intelligent Sleep Mode, Saves Battery Life)
By sensing the vibration generated from your machinery, the Kappa sensor can enter an ultra-low power mode to save battery life. As the machine turns on, the sensor will start to capture vibration data again with the first waveform being taken at a key moment during the duty cycle of your machinery
- Auto Ranging (Max Pk-Pk of 128G, High sensitivity at +/-8G)
All machinery is different. Most machines are designed to reduce the amount of vibration entering the system, so being as sensitive as possible is key to discovering certain faults. With a minimum range of +/-8G the Kappa sensor will detect even the smallest faults. Other applications are designed to induce vibration as part of the process, causing a very high energy signal. The Kappa sensor will automatically scale up to +/-64G to cope with this increased vibration, ensuring every high energy peak is captured. Our robust Auto-Ranging technology will ensure every waveform is captured at the right range
- Smart Technology
Kappa X features all the benefits expected of a smart sensor as standard. Smart Wake technology enables the sensor to enter ultra-low power mode which preserves battery life. Auto Ranging allows the sensor to automatically scale up to +/-64G to cope with peak energy exerted by the machine being monitored. With the ability to upgrade firmware and a replaceable battery, Kappa X features one of the best wireless sensor lifespans on the market

RMS Case Studies
Fan Bearing Distress
Greased – Food Sector
A great example showing how the Kappa X wireless sensor highlighted a lubrication issue on a fan bearing that was promptly rectified by the application of grease with remote monitoring support.
Gearbox Brg Defect
Critical vibrating cleaning screen for a food production factory. Vibrating screen, 2 off gearboxes run at 200mm/sec RMS 840 RPM. Bearing defect monitored, avoided plant shutdown until end of production campaign saving thousands of pounds in operating costs.
Fan Unbalance Problem
Power Plant – Food Sector
A sharp increase in 1X fan vibration levels prompts an investigation. With minute by minute data the team could look back at when the increase started, giving clues for the root cause. This lead to deeper inspection until the root cause was rectified.
Fan Bearing Defect
CHP Power Plant
Kappa X picked up a bearing defect on a large fan, the fault was tracked using the data until an planned window for replacement became availiable.
Pump Blockage Problem
The client was experiencing repetitve blockage problems on vertical pumps and was unable to accurately identify and resolve the issue ahead of pump failure.
