Siemens Milltronics MFA 4p Motion Alarm Controller

Siemens Milltronics MFA 4p Motion Alarm Controller

Product Code: 7MH7144

Manufacturer: Siemens


Siemens Milltronics MFA 4p motion failure alarm controller is a highly sensitive single setpoint motion sensor system, used with Milltronics MSP probes.

The MFA 4p detects changes in the motion and speed of rotating, reciprocating or conveying equipment. It warns of equipment mal function and signals through contacts to shut down machinery in case of a slowdown or failure. Its reliability makes it a cost-effective way to protect valuable process equipment.

The single setpoint system suits most industrial applications. This versatile unit can be used on tail pulley shafts, driven pulleys, motor shaft sensing, belt or drag conveyors, screw conveyor flights, bucket elevators, fans and pumps.

A special feature is the adjustable 0 to 60 second time delay, allow ing the monitored device to accelerate to normal running speed before monitoring begins. A wide range of probes are available to suit specific needs, including high temperatures and corrosive installations. The CE and UKCA approval allows the MFA 4p to con sistently meet the needs of the mining aggregate, cement and other primary and secondary industries.

Key Applications: tail pulleys, motor shaft sensing, screw conveyor flights, bucket elevators
