4B Braime Auto-Set™ Remote
The Auto-Set Remote series RF capacitance point level monitors are designed for high temperature (250°C) or vibration applications to detect high, intermediate, or low levels of liquids, powders and free flowing granular solids stored in tanks, bins, silos or other containers.
The Auto-Set Remote has a din rail mounted remote control unit with simple push-button calibration. The remote control unit connects to the transducer, which is mounted in a suitable enclosure close to the probe. For applications below 120° C or without any vibration, the transducer can be mounted within the polypropylene probe housing. Once the Auto-Set Remote is calibrated for the application it never has to be re-calibrated. Data is stored in non-volatile memory so it is not affected by power loss. A four digit LED display shows set values for uncovered, covered and trip settings, allowing simple set-up and adjustment. A set of voltage-free changeover relay contacts are actuated when the level of the material in the container reaches the probe. The unit incorporates a unique power shield which automatically compensates for material build-up around the probe and on the sides of the container, preventing false indication. The Auto-Set Remote is top or side mountable with stainless steel probes lengths up to 10m long, and can be used with container walls up to 7.5cm thick.
4B Braime B400 Elite Beltswitch
The B400 Elite Beltswitch belt misalignment monitor uses 4B Touchswitch sensors to monitor belt alignment in bucket elevators and conveyors. Each control unit incorporates two independent monitoring circuits for early detection of belt misalignment on one or two bucket elevators / conveyors. The 4B Touchswitch is an electro-mechanical limit switch with no moving parts. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage free relay contact. Status LEDs on the control unit indicate the alignment condition of the belt, while internal relay contacts provide alarm and automatic shutdown of the elevator when hazardous misalignment conditions are detected.
4B Braime Bulldog
The Bulldog alignment and rip detection switch is an electro-mechanical system designed to detect dangerous misalignment of the conveyor and also detection of belt tear damage. The switch will detect horizontal misalignment of belts when contact is made with the roller, the roller arm will be forced to pivot by the belt activating a switch at 20º to trigger an alarm, and 35º to trigger a shut down procedure of the conveyor. The sensors are usually installed in pairs on opposite sides of the belt.
A steel flexible wire is set below the running conveyor belt approx 20-30mm attached by a rare earth magnet at each end. If the belt is ripped or damaged the wire is pulled away releasing the magnet connection which in turn will activate a switch.
4B Braime CSA Touchswitch™
The Touchswitch is an electro-mechanical limit switch with no moving parts, which detects tracking and misalignment problems on bucket elevators and conveyors. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage free solid state relay output. This output signal is used to immediately alarm and ultimately shutdown the machine.
The face of the sensor is made from hardened and annealed stainless steel, not soft brass or aluminium, so wear life is longer when a belt contacts it. The sensor is not affected by dust or material build up and will still work when completely covered by material. An external test wheel allows for quick and simple sensor/system testing. The sensors are usually installed in pairs on opposite sides of the machine. The sensors can be connected directly to a PLC input, or for greater safety, to a central independent monitoring system, such as Watchdog Super Elite, IE-Node or the T500 Hotbus system.
4B Braime F500 Elite Fieldbus Gateway (W)
This version of the F500 Elite Fieldbus gateway has been designed to work as a Watchdog Elite communications gateway and allows up to 10 Watchdog control units to be networked together through RS-485 communication BUS. The Watchdog data is then converted to a Fieldbus protocol. Supported protocols include: Ethernet/IP, Modbus TCP, Modbus RTU, DeviceNet, Profibus and others on request.
4B Braime HazardMon.com®
HazardMon.com® is a secure cloud based hazard monitoring solution providing status notifications and data logging for bucket elevators and conveyors. Live system status, graphs and historical data can be viewed on any web-enabled device (smartphone, tablet PC, desktop or laptop computer). Emails can be sent to notify users whenever a change in the system's health is detected. An automated maintenance feature allows site operators to verify that all sensors on the system are operational and working correctly.
Hazardmon.com works in conjunction with 4B's Watchdog Super Elite™ and T500 Elite Hotbus™ control systems for bucket elevators and conveyors. Both multi-function systems are specially designed to monitor equipment for belt misalignment, belt speed, continuous bearing temperature, pulley alignment, level and plug conditions.
4B Braime Heavy Duty Whirligig®
The Heavy Duty (HD) Whirligig is a fully guarded target for easy mounting of motion sensors. It is suitable for use with 4B's range of inductive proximity sensors including the M100 Stopswitch, P100 Proxswitch, and P300 Proxswitch. Used on conveyors, bucket elevators and other rotating machinery, the HD Whirligig monitors shaft speed for continuous, low speed or high speed conditions. The sensor (sold separately) inserts into the housing of the HD Whirligig and the complete assembly bolts to the machines shaft through a 5/8” UNC tapped hole. Machine vibration or movement does not affect the performance of the sensor as the whole assembly moves with the shaft. The all stainless steel construction and sealed twin stainless steel bearings make the HD Whirligig ideal for use in corrosive and other extreme environments. With the HD Whirligig, sensor installation is now simple, safe and reliable.
4B Braime Hotbox Node – SN2 (Speed Node)
The SN2 is a two input speed node, powered by 24 VDC. The node is able to monitor two independent pulse (speed) sources for dangerous under speed conditions. The SN2 will support pulses which are PNP or sourced. The Node has a unique 4 digit address which is used to communicate to the T500 via a two wire RS485 connection. The SN2 processes information from electrical inputs into network data. The data is passed down the network whilst local relays are activated for shutdown / alarm procedures.
4B Braime Hotbox Node – TN4 (Input Node)
The TN4 is a four input sensor node, powered by 24 VDC. Each input can be an NTC thermistor, PTC thermistor or Volt-Free Contact input; the types may be interchanged on a single node. The Node has a unique 4 digit address which is used to communicate to the T500 via a two wire serial RS485 connection. The TN4 Node processes information from electrical inputs into network data inputs for WDB, Binswitch or Touchswitch.
