purePULSE | Wireless true RPM-sensor

purePULSE is an easy to install long range wireless speed sensor made for contactless precise measurement of revolutions per minute. The speed sensors detect the motion of ferromagnetic structures, such as gearwheels or shafts, and in combination with pureMEMS it becomes the perfect tool for analysing applications with variable speed.

Speed is the trigger

purePULSE triggers the measurement of speed and thus measures during a time interval determined by the customer. All data is collected in pureSignal's cloud service and provides a complete overview of speed and vibration measurement.

It is possible to do long-range true RPM monitoring, completely wirelessly on machines with variable speed and record operating time with great accuracy.

The easy and flexible installation makes it possible to monitor complex applications in harsh environments. By combining purePULSE with pureMEMS you get the most vital parameters (RPM, temperature and vibration) for your machines – all in pureCLOUD.
