WDB8 Bearing Temperature Sensors: Combined Heat and Speed Control

Looking for reliable WDB8 bearing temperature sensors? WDB8 series from 4B Braime Components (UK) combines temperature (NTC/PT100/PTC) and speed monitoring in one sensor. Screws into bearing with grease nipple, detects overheating (+3°C, 60–90°C thresholds) and slip (>10%). Prevents fires, breaks, and downtime at elevators, mills, and ports.

Why choose WDB8?

• Dual control: Temperature + speed, ±1°C and <1% accuracy.

• Embedded mounting: 1/4” BSPT, 3 m cable.

• Durability: IP67/IP68, -40…+120°C, ATEX Zone 20/21.

• Integration: SPDT relay, 4-20 mA, Modbus, DCS.

• Savings: Fire risk -95%, payback 3–6 months.
