Belt misalignment monitoringWith a 30 till 40% share of all company dust explosions, it’s easy to say that a bucket elevator is a dangerous installation with a real explosion risk. This can easily be prevented and damage can be limited with our range of belt misalignment systems for vertical and horizontal transportation at conveyor belts.
Belt misalignment monitoring -
Bearing temperature monitoring60% of the early malfunctioning bearings is caused by material fatigue as a consequence of continuous fluctuating pressures on the bearing its surface and the use of incorrect lubricants. Bearing monitoring sensors are able to detect damages in an early stage and prevent downtime and potential dust explosions.
Bearing temperature monitoring -
Speed monitoringTo detect belt slip in an early stage we offer several speed monitoring switches to make sure you are informed in time when the belt slips. They also safeguard applications from overspeed or underspeed.

Whirligig
Universal Shaft Sensor Mount
WG1A-BR – WG2A-BR – WG4A-BR – WG8A-BR – Universal Sensor
Universal Shaft Sensor Mount
EX II 2G 1D EE x m IIb T4 T 100°C zone 20, 21 & 22
Applications:
Fully guarded target for easy mounting of motion sensors. The ‘Whirligig’ three in one target/bracket/guard is suitable for all industry standard cylindrical or DIN style inductive sensors including our M100, M300 and M800 speed sensors.
The sensor bolts to the whirligig base plate and the complete assembly bolts to the machines shaft. The installation of speed sensors is now simple, reliable and fully guarded.
Shaft or machine vibration does not affect the performance of the sensor, as the whole assembly moves with the shaft.
Functions:
Fully Guarded Target for Easy Mounting of Motion Sensors
Suitable for all 4B sensors & other industry standard 18/30mm cylindrical sensors
Not affected by shaft or machine vibration
Easy Installation – Only Requires 1/2″ UNC Tapped Hole in the machine’s shaft
Optional Magnetic Connector “Magcon” simplifies mounting; no need to drill or tap the shaft
Options:
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 Whirligig sensor can be connecting direct to a PLC or for increased security to an independent monitoring system such as the B400 ELITE, WATCHDOG ELITE or T500 Hotbus system.
M100 INDUCTIVE STOPSWITCH
M100 Inductive proximity Stopswitch
Detect Dangerous Underspeed Stop Conditions
M1001V10A – M100 Stopswitch 2-Wire
24-240 VAC/DC
Ex II 1D T100°C Zone 20
Applications:
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.
Functions:
Signals “stopped condition” on conveyors, bucket elevators, fans and all rotating machinery
Inductive proximity sensor which detects rotating metal target
Single trip set-point signal if no pulse is received within 4 seconds
Non-contacting & failsafe
Universal Voltage: 24-240V AC/DC

M3005V10AI – 5-Wire M300 Inductive proximity Slipswitch
12-240 VDC / 24-240 VAC
Ex II 1D T100°C Zone 20
Applications:
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 underspeeds 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. During installation the M300 is set to the normal machine shaft RPM by calibrating with the magnet provided. The internal microprocessor sets the underspeed output to operate at exactly 20% below normal machine shaft RPM, so users are able to use the M300 output for automatic shutdown during a dangerous underspeed or belt slip condition.
Functions:
Microprocessor controlled underspeed monitor
Signals underspeed for bucket elevators, conveyors and all rotating machinery
Inductive proximity sensor in 30mm diameter housing, which detects rotating metal target

Toepassing:
The M800 Speed switch protects rotating equipment from dangerous underspeed conditions (elevator legs, conveyors, grinders, mixers, fans, etc.) The Inductive sensing devise, located in the nose of the M800 detects a rotating metal target on a shaft. If the machine speed falls by 10% or 20% below its nominal RPM, the monitor provides output signals for alarm and / or shutdown of the machinery.
