WGB1830 : Stainless steel mounting bracket for 18 mm dia.or 30mm dia.cylindrical sensors
Whirligig: Target wheel ATEX approved
WG1A-BR: 1 Pulse per revolution
WG2A-BR: 2 Pulse per revolution
WG4A-BR: 4 Pulse per revolution
WG8A-BR: 8 Pulse per revolution
The Mag-Con™ (MAG2000) is an optional magnetic connector that screws onto the Whirligig and magnetically couples it to the shaft being monitored. The Mag-Con is made from stainless steel, has a holding force of over 150 lbs. and can withstand speeds up to 300 RPM.
The M100 Stopswitch is a simple inductive shaft speed monitoring device. The self-contained unit has a single set point, which signals when the shaft has stopped rotating. It can be used for process control, motion detection and stopped shaft indication. An inductive sensing device located in the nose of the M100 enclosure will detect a metal target. This target can be an existing bolt head or device attached to a shaft. The M100 Stopswitch requires no calibration and provides an output when the shaft has stopped rotating.
The M300 Slipswitch is a simple inductive shaft speed monitoring device. The self-contained unit has a single set point, which signals when the shaft speed has dropped by 20% of normal running speed. It is used for detecting dangerous slow downs and underspeed on conveyors, bucket elevators, airlocks, mixers, fans, grinders and many other machines. An inductive sensing device located in the nose of the M300 enclosure will detect a metal target. This target can be an existing bolt head or device attached to a shaft.
The M800 Elite Speed Switch is designed to detect belt slip, belt underspeed, stop motion, low speed or zero speed on bucket elevators, conveyors, airlocks, mixers, fans, grinders and many other rotating machines. Totally sealed and simple to calibrate, the M800 Elite works in the harshest of conditions.
The P800 Proxswitch is an inductive sensor designed to detect shaft speed, shaft position, gate position, or object presence.
The Milli-Speed Switch with 4 - 20 mA output is designed to detect belt slip, belt underspeed, stop motion, low speed or zero speed on bucket elevators, conveyors, airlocks, mixers, fans, grinders and many other rotating machines. Totally sealed and simple to calibrate, the Milli-Speed works in the harshest of conditions.
Does the Whirligig® come with a sensor?
No, sensors are sold separately.
What is a Mag-Con™?
The Mag-Con™ is an optional accessory that allows you to magnetically attach the Whirligig® to a shaft without the need to drill and tap. It has a holding force of over 150 lbs. and can handle speeds up to 300 RPM.
Preventative maintenance can help reduce the risk of equipment failure and consequent downtimes. When it comes to monitoring your bucket elevators and belt conveyors, 4B can recommend you the ideal combination of sensors and monitoring systems to suit your requirements and budget.
4B provides an extensive range of their own ATEX / IECEx / CSA /GOST- R approved hazard monitoring systems, misalignment switches and bearing temperature monitors and level controls. We can offer you anything from a replacement sensor to a fully integrated hazard monitoring system which can be operated either as a stand-alone system or connected to your PLC.
And if you do not want to install hazard monitoring sensors on every piece of equipment in your plant straightaway, we can offer you a scalable solution starting with carefully chosen equipment and systems that can be expanded at a later date to encompass other machines in the plant.
We can also offer you an installation service, and we do provide a competent after-sales technical service to help you overcome any technical problems with your monitoring equipment.
