SIEMENS 7ML5033-1AA00-2A Level Sensor

Siemens 7ML5033-1AA00-2A Level Sensor / Level Controller (MultiRanger 100)

 

 

The Siemens 7ML5033-1AA00-2A is a MultiRanger 100 ultrasonic level controller used for non-contact continuous level measurement. It works with ultrasonic sensors to measure liquid, slurry, or solid levels in tanks and open channels, and provides relay outputs for control functions such as alarms and pump control.

This is a wall-mounted control unit, not a direct probe sensor.
