M800 Elite: Speed Sensor for Elevators and Conveyors with Extended Monitoring

Looking for a reliable M800 Elite speed sensor? M800 Elite from 4B Braime Components (UK) is an advanced inductive sensor for precise shaft, bucket, or conveyor roller rotation control. With extended detection range (up to 50 mm) and high sensitivity to metal elements, it instantly detects belt slip, speed reduction, or stoppage. Ideal for grain elevators, feed mills, flour mills, and port terminals, integrating with DCS for automated safety.

Advantages of M800 Elite 4B Speed Sensor

Why choose M800 Elite 4B Braime?

• Extended sensitivity: Detects metals up to 50 mm away, responds to deviations from 1 rpm with <0.5% error.

• Contactless inductive principle: No wear, compatible with Whirligig for pulses, 10+ year lifespan.

• Harsh environment resistance: IP68 housing, -40°C to +120°C, ATEX Zone 20/21 dust.

• Universal outputs: PNP/NPN, SPDT relay, optional 4-20 mA, Modbus for SCADA.

• Automatic alarming: On >10% slip or stop — instant controller signal.

How M800 Elite Speed Sensor Works

The M800 Elite speed sensor mounts 20–50 mm from the shaft or belt. It captures passing metal buckets, bolts, or Whirligig markers, generating pulses for rpm calculation. On deviations (speed drop, misalignment), relay opens, triggering emergency stop. This protects against:

• Belt or chain breakage

• Bucket fall into shaft

• Bearing overheating from uneven operation

Main M800 Elite Models

M800 Elite Standard — Base Version for Elevators

Inductive sensor with PNP/NPN output. Range: 1–5000 rpm. Distance: up to 50 mm. Ideal for bucket elevators. Protection: IP68, ATEX. Compatible with Whirligig WG4.

M800 Elite Modbus — Digital Interface Variant

Additional Modbus RTU for PLC integration. Same range, with event logging. Suitable for complex DCS.

Compatibility with 4B Systems

Works with Watchdog™ Super Elite, Milli-Speed, WDA, T500 Hotbus. No adapters needed for standard shafts.

Application Areas

Ideal for:

• Grain elevators (50–1000 t/h)

• Feed mills

• Flour milling complexes

• Ports with high-speed conveyors

• Bulk material warehouses

Installation on Elevator

On top pulley of elevator, M800 Elite monitors bucket rotation. Dust buildup slip (15%) — PLC signal, feed block. Payback — 3 months.

Use on Conveyor

For belt lines, sensor tracks rollers. Stoppage — instant alarm, preventing misalignment.
