WDB83x contact bearing sensors offer protection from overheating with built-in grease nipple, NC circuit, and PLC/monitor compatibility—simple, safe, reliable. The WDB83x series is a range of contact bearing temperature sensors designed to provide reliable over-temperature protection for bearings. Each sensor is manufactured to screw directly into the bearing housing for direct contact monitoring and is equipped with a built-in grease nipple, allowing for lubrication without the need to remove the sensor. The sensor includes a fixed two-core cable for easy connection to a monitoring device or junction box. As the wiring is not polarity sensitive, installation is simplified, and the cable can be extended in the field if needed. All sensors in the WDB83x series operate in a normally closed (NC) state, meaning the circuit remains closed under normal conditions. When the preset temperature limit is exceeded, the bimetal element opens the circuit to trigger an alarm. The circuit automatically resets once the temperature drops back below the reset threshold. These sensors are primarily used for over-temperature protection in

The WDA4 is a non-contacting high-power, extended range magnetic proximity sensor, for alignment and motion detection on bucket elevators and conveyors 4B have just launched the 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

4B has introduced the Encoder-Flex 1024, designed to monitor the position of rack and pinion gates, as well as shaft speed and angular position of distributors. 4B Group has introduced the Encoder-Flex 1024, designed to monitor the position of rack and pinion gates, as well as shaft speed and angular position of distributors. The new, ATEX-approved Encoder-Flex 1024 is changing the way slide gates are monitored. This compact rotary shaft encoder uses advanced technology to deliver a precise position from 0 to 100%. With a compact, sleek design, the Encoder-Flex 1024 removes the bulkiness associated with traditional shaft encoders and adds the benefit of easy calibration. There is no need to open up the unit; simply apply an external magnet briefly to calibrate. Providing even more flexibility, resolution can be programmed for 1 to 1024 pulses per rotation. All electronics on the Encoder-Flex 1024 are housed in a sealed stainless steel enclosure and are encapsulated in epoxy, protecting the device from moisture and the elements and providing maximum reliability in the field. In addition, the Encoder-Flex 1024 provides

Sinfimasa presents a solution for dosing very fine, explosive bulk solids, in this case active ingredients of medicines. In a practical situation, dosing of 300 litres per hour of micronised bulk product (active ingredients of medicines) was required. As the substance was explosive, a machine with ATEX GAS 1 certification was provided. Sinfimasa designed a stainless steel 316 tube screw feeder, suitable for ATEX zone 1 (2G). A screw of 70 mm and a tube of 80 mm were chosen, so that there is a large clearance. The screw is driven by a 0.75 kW ATEX certified motor gearbox. All parts that may come into contact with the product, such as seals, plastics, grease, etc., are FDA-compliant thanks to the hygienic, easy-to-clean design. The product itself is a sticky product, so the tube is manufactured with a glossy polished (g220) inner surface and an industrial satin matt outer surface. In accordance with directive 2014/34/EU, equipment and protective systems intended for use in potentially explosive atmospheres must be designed with a view to integrating explosion protection. These

Utilizing industrial Ethernet and cloud connectivity to share real-time sensor data, alongside historical analytics, with your PLC of choice. 4B’s IE-Node is the future of hazard monitoring. Utilising industrial Ethernet and cloud connectivity to share real-time sensor data, alongside historical analytics, with your PLC of choice — the IE-Node is truly intelligent. Sample code for a variety of PLC brands is available to help you connect your entire system and keep every component in constant communication for unprecedented hazard protection. The IE-NODE operates by reading its sensor inputs and sending processed data when requested by another system (e.g. PLC). The units are equipped with an RJ45 Ethernet socket and supports PROFINET, EtherNet/IP and Modbus TCP/IP protocols for easy integration with Siemens, Allen-Bradley Rockwell, Modicon and other PLC’s or automation devices. The IE-NODE’s network configurator software provides a visual view of all devices on the network. It allows for easy identification of each unit on the network and allows for network settings to be changed as needed.

For all bulk goods. Individual paddle size. Selectable parameter-sets. Direct drive without a gearbox, powerful motor with miniature wing, pre-adjustable and selectable parameter sets for universal use - these are the main features of the MBA800 with rotating wing for level measurement. This sensor is a real allrounder from light to heavy bulk materials. The idea is old, but it was never implemented. The inspiration for the implementation of these ideas was the MBA-owned patent for magnetic coupling. The idea of the magnetic coupling has now been developed as an integral part of permanent magnetic synchronous motors. The direct drive variable speed motor control, parameters can be coordinated so that the various functions of the sensor can be adapted to different types of bulk materials and their properties in the application. So these individual adjustments of the stepper motor on the switching behavior, speed, detection and arrest-free switching can be selected in the sensor head. It is this parameter selection which makes the
