7MH7701-0AA00-0A SIEMENS Exclusive SITRANS WM300 MFA Motion Failure Alarm Original Brand New

The 7MH7701-0AA00-0A SIEMENS SITRANS WM300 MFA Motion Failure Alarm is an advanced, highly sensitive dual setpoint sensor system designed to ensure operational continuity across a wide range of industrial applications. This reliable motion detection system is engineered to identify changes in the speed and motion of rotating, conveying, or reciprocating equipment. It helps prevent costly breakdowns by triggering alarms and shutting down machinery when abnormalities are detected.

Compatible with Milltronics MSP and XPP probes, the WM300 MFA can support up to two primary probes and an additional two for differential speed monitoring (DSD). This allows it to function in scenarios where both high and low-speed detection is required, such as comparing head and tail pulley speeds on a conveyor system. The unit also supports non-contacting tachometer functionality (NCT) via an optional analog output module.

A key feature of this motion alarm is its adjustable delay setting, ranging from 0 to 60 seconds. This ensures that monitoring only begins once the equipment has reached its normal operational speed. The system is ideal for use in demanding environments such as mining, cement, and aggregate industries, where equipment protection and uptime are critical.

Overview

The SITRANS WM300 MFA provides advanced motion detection by monitoring for decreases or complete loss of motion. Designed to interface seamlessly with MSP probes, it offers industrial-grade performance for machinery such as motors, screw conveyors, fans, pumps, and elevators. Its robust alarm system enhances preventive maintenance strategies by identifying operational issues before they escalate.

Application

Used in motor shaft sensing, tail pulleys, driven pulleys, and other components, the WM300 MFA offers flexible and scalable monitoring. The twin probe design makes it suitable for systems requiring comparison between multiple moving parts, and its analog output option enables precise feedback when used as a tachometer.
