SIEMENS Motion Sensors

Siemens devices for process protection, particularly emphasizing the insensitivity to environmental factors such as dust, dirt, deposits, and humidity. The non-contacting acoustic sensors and speed sensors appear to offer precise monitoring capabilities for various systems. Additionally, the MFA 4p motion sensing probes and Millpulse 600 are designed to be resilient, with the ability to be mounted close to the ferrous target without being affected by moisture or dust build-up. These features showcase the advanced engineering and durability of these devices.

SIEMENS Milltronics MFA 4P

The Milltronics MFA 4p motion failure alarm controller functions as a highly sensitive single setpoint motion sensor system. It is designed to be used with Milltronics MSP and XPP probes, and it is capable of detecting changes in the motion and speed of rotating, reciprocating, or conveying equipment. In the event of equipment malfunction, it provides warnings and signals through contacts to initiate machinery shutdown if a slowdown or failure occurs.

Catalog Sheet Milltronics MFA 4P

Process Protection

The MFA 4p detects changes in the motion and speed of rotating, reciprocating or conveying equipment. It warns of equipment malfunction 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, allowing 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 consistently meet the needs of the mining aggregate, cement and other primary and secondary industries.

SIEMENS Milltronics MSP-7

The Milltronics MSP-7 is a robust 3-wire motion sensor designed to detect changes in the rotation and movement of ferrous equipment. It provides an NPN open collector output to PLCs, enabling it to warn of malfunctions and signal to stop or slow down equipment when connected to a PLC. This functionality helps prevent costly failures or downtime. It's worth noting that the MSP-7 is just one of the available models in this range.

SIEMENS SITRANS WM100

The SITRANS WM100 is a heavy-duty zero-speed alarm switch that operates without physical contact. It offers cost-effective equipment protection, even in the most challenging conditions. This rugged unit is designed to withstand dust, dirt, buildup, and moisture, making it particularly well-suited for implementation in primary industries such as mining, aggregate, and cement.

Catalog Sheet SITRANS WM100

Process Protection

This rugged unit is impervious to dust, dirt, build-up and moisture and is ideal for such primary industries as mining, aggregate, and cement. Operating where other systems are prone to failure, the non-contacting design eliminates the need for lubricating, cleaning and part replacement. Downtime and clean-up expenses associated with conveying equipment failure are reduced by the SITRANS WM100. It alarms to minimize spillage, prevent extensive damage or even fire caused by belt slippage at the head pulley, and warns against conveyor malfunction.

The SITRANS WM100 has built-in selectable start delays and 1 Form C relay contact. With an aluminum body, it operates from ?40 to +60 °C (?40 to +140 °F).
