Whirligig®
Universal Shaft Sensor Mount
WG1A-BR, WG2A-BR, WG4A-BR, WG8A-BR

The Whirligig® is a fully guarded target for easy mounting of motion sensors. It is a universal shaft sensor mount suitable for all industry standard cylindrical or DIN style inductive sensors including 4B's M100, M300, and M800 speed switch sensors.

The sensor bolts to the Whirligig base plate and the complete assembly either bolts to the machines shaft through a M12 tapped hole, or is connected magnetically using 4B’s patented Mag-Con™ adaptor. Shaft or machine vibration does not affect the performance of the sensor, as the whole assembly moves with the shaft. With the Whirligig, installation of speed sensors is now simple, safe and reliable.

Mag-Con Magnetic Connector

Mag-Con™ 高磁快速连接器
Mag-Con Magnetic Connector

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.

M3003, M3008 & M3007 Slipswitch

The M300 Slipswitch is an easy-to-use inductive proximity shaft speed monitoring device with an adjustable 0 - 30 second start-up delay, all housed in a 30 mm diameter moulded body. 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 down and underspeed conditions on conveyors, bucket elevators, air locks, mixers, fans, grinders and many other machines. 

No connection is necessary between the sensor and the equipment being monitored. The proximity sensor detects a stud or bolt mounted on a shaft, or other suitable target. Ideally, the target should be of ferrous metal, but non-ferrous metal will be detected at a shorter range. Maximum range of ferrous targets is 8 mm (5/16”) and for non-ferrous targets is 5 mm (6/16”), assuming a 20 mm (3/4”) diameter target. Smaller targets may be used but operating distances will be reduced.

M1003 Stopswitch

The M1003 Stopswitch is a simple inductive shaft speed monitoring device. The self-contained unit, 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 M1003 Stopswitch requires no calibration and provides an output when the shaft has stopped rotating.

M800 Speed Switch

M800 sensor inductivo de velocidad
M800 Speed Switch

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.

An inductive sensing device located in the nose of the M800 Elite enclosure will detect a metal target. This target can be an existing bolt head or device attached to a shaft. During installation the M800 Elite is set to the normal machine shaft RPM by calibrating with the magnet provided. The internal microprocessor sets the alarm and shutdown relays.

Milli-Speed Switch

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.

An inductive sensing device located in the nose of the Milli-Speed enclosure will detect a metal target.  This target can be an existing bolt head or device attached to a shaft, such as 4B’s Whirligig® sensor mount.  During installation, the Milli-Speed is set to the normal running RPM by simple magnetic calibration.

PRODUCT DETAILS

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.

Hazard Monitoring Design Service

Hazard Monitoring Design Service

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 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.

To get a recommendation from our engineers, please fill in the electronics questionnaire below. Please fill this form in as accurately as possible to allow us to deal with your enquiry more effectively.
