Bosch Rexroth IVAS Intelligent Vibration Sensor

Bosch Rexroth introduces its intelligent vibration analysis solution IVAS.

• Compact sensor package
• MEMS technology achieves optimum performance value
• Delivers valuable live information to help ensure increased machine availability in off-highway applications 
• Uses modern sensor technology and edge analytics to work out the relevant structure-borne noise properties of rotating components for further analysis in control units, master computers or the cloud
• Only relevant properties are transmitted to a cloud solution (e.g. Bosch Rexroth’s Connected Off-Highway Solution COS) in accordance with the smart data principle
• Can be seamlessly connected to various front ends via connectivity control unit and corresponding software in order to monitor machine health
• Anomalies are made visible
• Automatic frequency analysis eliminates major hurdle that would otherwise hinder measurements of structure-borne noise from being carried out
• Writes the root mean squares of the vibrations in the form of a message that is easy to read on CANbus, eliminating need for technicians to assess large amounts of raw data using external Fourier transforms
• Enables direct assigning of frequency anomalies to individual cases of damage and defines next steps to be taken
• Can be both an enabler and part of an end-to-end solution
• Comes as a complete stack in various configurations consisting of sensor hardware and embedded software including a connectivity control unit as well as edge analytics and cloud services
• Information gathered and pre-assessed is transmitted via connectivity control unit to a cloud solution
• Vehicle data and trends can be visualized, and sensors and other IoT devices can be managed there
• Bosch Rexroth’s Connected Off-Highway Solution COS can be used as a cloud solution and allows retrieval of information from other cloud solutions via the REST interface
• Cube housing measures 36 x 36 x 34.1 mm³ (0.0022 x 0.0022 x 0.0021 in.³) and features 5-pin M12 CAN interface
• Houses a temperature sensor, 1-axis accelerometer with 20-kHz bandwidth and sensitivity of 200 mg, as well as a 3-axis accelerometer with 3-kHz bandwidth and sensitivity down to 0.06 mg
• Features protection class IP67
• Measurement range of temperature sensor runs from -40-105  C (-40-221 F)
