Motion Sensing Probes
The Milltronics MSP-7 motion sensing probe can detect changes in the rotation and movement of ferrous equipment. When connected to a PLC it can warn of malfunction and signal to stop or slow down equipment, preventing costly failure or downtime. This level of reliability makes it a very cost-effective sensor.
The Milltronics MSP-7 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.
An NPN open collector 3-wire output allows for versatile connection to most PLC models and a large dynamic range ensures that the MSP-7 can detect changes in target speed for a variety of applications.
Key Applications: tail pulleys, motor shaft sensing, screw conveyor flights, bucket elevators
The Motion Sensing Probes are used with the Milltronics MFA 4p to detect motion. The different probes are specialized for different industrial environments.
SITRANS WM100 is a heavy-duty zero-speed alarm switch. This non-contacting unit provides cost-effective equipment protection even in the harshest conditions. It is rugged enough to be impervious to dust, dirt, build-up and moisture, and is ideal for such primary industries as mining, aggregate, and cement.
SITRANS WM100 motion sensor operates 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. Failure alarms minimize spillage and prevent extensive damage. The SITRANS WM100 can prevent fires caused by belt slippage at the head pulley and warn 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).
Key Applications: tail pulleys, driven pulleys, motor shaft sensing, screw conveyor flights, bucket elevators
- Up to 100 mm (4″) gap between SITRANS WM100 and targets
- Rugged and low maintenance; suitable for tough environments
- 1 SPDT Form C relay contact
- Provides cost-effective protection
- Visual indication of target triggered pulse
SITRANS WM300 MFA
A compact, rugged and reliable controller for motion monitoring
The SITRANS WM300 MFA is a highly sensitive dual setpoint motion sensor system, used with up to 2 MSP and XPP probes. It is capable of hi/lo setpoint as well as differential monitoring with 2 additional probes.
The SITRANS WM300 MFA detects changes in the motion and speed of rotating, reciprocating or conveying equipment which is used to indicate a slow down or failure of machinery. Early warnings of a malfunction can prevent damage to valuable process equipment. The dual setpoint system suits most industrial applications.
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. SITRANS WM300 MFA consistently meets the needs of mining aggregate, cement and other primary and secondary industries.
Key Applications: tail pulleys, motor shaft sensing, screw conveyor flights, bucket elevators, fans, pumps
- Up to 4″ (100 mm) gap between target and probe
- Over and under speed setpoint detection
- Setpoint adjustment range 2 to 5000 Hz (120 to 300,000) ppm
- Adjustable start-up time delay
- Visual indication of probe operation and relay status
- General purpose, suitable for majority of applications: rugged probe designs provide unmatched reliability
