Which sensor measures speed and detects starts and stops?

Choose a DHMSCare DS320, DS321, DS400 or DS420 when you need rotating speed and start/stop detection as well as vibration and temperature. The DS320 and DS321 add edge AI, analysis done inside the sensor itself, to the DS310 and DS311. The DS400 and DS420 measure up to ±60 g from 0–8000 Hz for machines that run at changing speeds or stop and start often.
