The Sensoteq Chi sensor provides instant feedback on a machines efficiency and health direct to our Android app, with advanced analysis options in the cloud. Chi has been designed as a companion for technicians, installers and manufacturers to quickly assess machinery in the field or before it leaves the factory. Suitable for all machine types that have a rotating element or generate oscillating patterns. Proven to work in all industries

Vibration Analysis

The first step in any machine health check-up is to check for unusual vibration patterns. Sensoteq Chi enables you to measure time waveforms and frequency spectrums, detailing the acceleration, velocity, and displacement data for one sensor. Use the data collected to diagnose faults within bearings on rotating equipment, such as pumps, motors, compressors and many more applications

  • On-Demand Measurements
  • Up to 2.5kHz Fmax

Hammer Test

They say when all you have is a hammer, every problem looks like a nail; but if you add Chi into the mix, you can also detect the natural frequencies of your machine, structure or sub-structure! By striking a machine with enough force you will generate oscillations that resonate at the natural frequency of your machine. This is critical information to understand - as you want to ensure the running speed of your machine avoids these frequencies or it could induce serious problems

  • Detect Natural Frequencies
  • Simple Process

Stroke Detection

Using our unique algorithms, the Chi sensor will calculate all the required information for the end user to understand the operating efficiency of the machine. By comparing the data between all sides of the machine, the user can determine the proportional difference as a percentage - highlighting faults that lead to lower product/material throughput. Chi is perfectly suited for those applications where improved efficiency means higher returns

  • Rapid Sample Rate
  • Up to 4 Sensors
  • Visual Reporting

Cloud Connected

Connect to the internet (or save data for later upload) to store your measurements in our cloud servers. Using the Analytix Platform you can access all this data at the touch of a button. View historical or recent data sorted by machine name or measurement type. By utilising the power of the platform you can view this data in great detail, with advanced features and tools to give you even greater insight into the behaviour of your machines
