Bucket Elevator Monitoring

Bucket Elevator Hazard Monitoring for Safe Bulk Material Handling 

Bucket Elevators are an economical means of elevating bulk raw materials, typically straight up at 90 degrees before discharging the material at the head of the elevator. Electro-Sensors provides a line-up of bucket elevator sensors designed to keep your equipment and employees safe. These systems help operators effectively monitor bucket elevator conditions such as temperature, belt alignment, and speed to reduce risk of a dust explosion.

Bucket Elevator Monitoring Equipment

1. Bearing Temperature Monitoring

Bearing temperature sensors are 2-wire, loop-powered, and provide a 4-20 mA analog output. Included is an attachment probe, sensor and signal conditioner. The TT420Z-LT (1/2") screws into a 1/8" NPT grease fitting tap and provides a grease fitting for bearing lubrication and a compression fitting for setting probe depth. The sensor is FM approved, dust ignition-proof for Class II environments. 

2. Belt Alignment Monitoring 

Belt alignment products for bucket elevators include rub block door assemblies (3 models) and accompanying temperature sensors.  These belt misalignment sensor systems detect tracking issues before they cause damage. The TT420S-LT temperature sensor features a stud mount adapter for easy attachment to a Rub Block Door Assembly. The sensor is 2-wire, loop-powered, and provides a 4-20 mA analog output. It is FM approved, dust ignition-proof for Class II environments.

3. Shaft Speed Monitoring 

Shaft speed monitoring can be done with a bucket elevator speed sensor or speed switch. In this example shaft speed is being monitored by our ST420-DI shaft speed sensor and is mounted with EZ-18mm Mounting Bracket. This model is also 2-wire, loop-powered with 4-20 mA output and has FM Class II approval. Electro-Sensors produces many shaft speed monitoring solutions to best fit your application.

OSHA standards require that facilities in the grain industry with bucket elevators are equipped with a motion detection device that will shut-down the bucket elevator when the belt speed is reduced by no more than 20% of the normal operating speed. (1910.272(q)(5)
