Motion sensor protects process equipment


Siemens Process Instruments’ new Milltronics ME100 motion sensor has been designed to protect process equipment in a variety of applications.

"The ME100 monitors ferrous targets mounted to drive sprockets or rotating pulleys. It can also monitor shaft-drive keys and screw conveyor flights. Its magnetic field detects any change in motion (increase, decrease or lack of motion) and prompts an alarm that notifies the operator of a problem. Alternatively, it will automatically shut down the equipment if the ME100 is tied into a motor-control scheme."

"The ME100’s strong magnetic field allows effective monitoring of ferrous targets up to 100mm away, depending on target size and speed. Detection is unaffected by dust or moisture and is reliable within a wide temperature range (–20oC to 65oC). The sensor has a 316 stainless steel body and mounting clamp and offers 24V DC operation for improved safety. It meets all the requirements for CE compliance."

The ME100 HL (high/low) model has a self-calibration feature and alarms at speeds both above and below the calibration point. Digital electronics detect over-speed or under-speed situations. The ME100 ZS (zero speed) model has pre-set calibration and offers simple alarming of machinery approaching zero speed.
