4B Hazard Monitoring Special

Hello! Welcome to our 4B Linkedin Newsletter – this month with a focus on Hazard Monitoring.

At 4B, we always work on new products and solutions to make bulk handling operations safer, and we are excited to reveal our latest innovations.

Now available - WDA4 Motion Alignment Sensor

We have just launched our upgraded version of the WDA, the WDA4, now with the ability to reverse the state of the continuous output (normally energised or normally de-energised). This sensor is a great choice for measuring speed and alignment on bucket elevators and on other applications such as using the WDA switch as broken/slack chain detector on drag chain conveyors or as a non-contact speed switch for screw conveyors.

The WDA4 supersedes the WDA3 – meaning that the WDA3 is no longer ATEX approved. The WDA4 complies with the latest ATEX and IECEx certification but is not currently CSA approved.

The WDA4 is a non-contacting high-power, extended range magnetic proximity sensor, not affected by dust or material build up, used to detect moving ferrous material up to 75mm away from the sensor.

The sensor is designed for use with bucket elevators to detect the buckets in order to measure speed and alignment. It can also detect screw conveyor flights, and ferrous bolts when attached to non-ferrous buckets. A more specialized use of the WDA sensor is for broken/slack chain detection.

The WDA4 is used in conjunction with a PLC or with 4B's Watchdog? Elite or A400 Elite control units. Two output signals are provided: one signal is a pulse output, representing each bucket detected: the second signal is a continuous output when moving buckets are detected. The continues output can be wired normally energized or normally de-energized.

Meet the 4B Milli-Sensor Range

4B Group expand their ATEX-approved “Milli” range with the introduction of the Milli-Vib and Milli-Con vibration sensors.? Both are designed for heavy duty industrial applications for measurement of vibration (Milli-Vib) and combined vibration / temperature (Milli-Con).? Like other sensors in the “Milli” range, the Milli-Vib and Milli-Con carry approvals for the highest levels of dust hazard protection to international standards (ATEX, IECEx & Class II Div 1).?

Made from robust stainless steel, the sensors are suited to the harshest environments and provide additional insight into the performance and condition of machines and individual mechatronic and mechanical components, such as bearings, motors, gearboxes, etc.?

With 4-20mA loop powered output equating to two sensing range options 0-25mm/s or 0-50mm/s velocity, the Milli-Vib is suited to most vibration sensing applications.? Additionally, the Milli-Con incorporates surface temperature monitoring using either a NTC thermistor or PT100 RTD to give full condition monitoring capability.

Milli-Speed – (under)speed / belt slip monitoring

Milli-Temp – bearing temperature monitoring

Milli-Vib – vibration monitoring

Milli-Con – vibration & surface temperature monitoring

4B Maintenance & Commissioning Services

Did you know............ that we offer Annual Site Inspections ????? and Commissioning? - Our 4B Tech Team performs site visits to make sure that systems are in working order, settings up-to-date, voltages correct, all sensors are working correctly and no faults. Peace of mind for our customers – and of course a detailed report with findings and recommendations.?
