Which sensor measures speed and detects starts and stops?

Choose a DHMSCare DT320, DT321, DT400 or DT420 when you need rotating speed and start/stop detection as well as vibration and temperature. The DT320 and DT321 add edge AI, analysis done inside the sensor itself, to the DT310 and DT311. The DT400 and DT420 measure up to ±60 g from 0–8000 Hz for machines that run at changing speeds or stop and start often.
