While the trend for large manufacturers is to automate a new plant in its entirety, small and medium-sized food and beverage processors rarely have the funds to automate their plants, turning them into lights-out facilities. Even some tier-one processors may find areas in certain operations where it may not make sense to over-automate.
Available with an analog output, the Banner Q4X laser distance sensor is used for fill level indication, part positioning, roll diameter, loop control and thickness/height verification; the sensor offers continuous measurement and sensing performance, in addition to resolutions as small as 0.15mm.
4B Components P800 Proxswitch proximity sensors have solid state relays for monitoring applications requiring a pulse output up to 120VAC/VDC for PLC integrations; they also can be used to detect shaft, gate or slide position, as well as object presence.
The ABB LMS100 SPDT switch is mounted on a level gauge with a magnetic coupling action that eliminates process contact and the need for seals, diaphragms, springs or torque tubes; it senses high or low levels within a vessel.
Based on diode array technology, the Perten DA 7440 SD NIR process sensor measures multiple parameters in all types of fried/baked snack foods; it does not require recalibration between batches and product changeovers.
