深圳市银飞电子科技有限公司一百分的仪器仪表 DREXELBROOKA Leader In Level Measurement SolutionsThePoint RFSeriesPoint Level Switch for Plugged Chute DetectionEliminate Costly Plugged Chuteswith Drexelbrook Sensors!Downtime is expensive and so is theclean up of process spills.Reliable detection of plugged chutes will keep yourplant running smoothly and virtually eliminate spillsthat occur because of plugged conditions.Drexelbrooks Flush-Mounted Sensorsreliably detect presence or absence of materialowing through chutes. If process material stopsowing due to a plugged condition, the system willalarm, allowing further action to occur (alerting anoperator, shutting down a conveyor belt, etc.). Thispermits the operator to prevent a problem beforeit happens.Intelligent Electronics Save Time andMoney Automaticallyrecognizesandignorescoatingstopreventfalsealarms.Rugged sensor design Universal power supply automatically detects &adjuststoinputpowersourcemakes these systems ideal for coal (pulverizer andtransfer chutes), wood chips, ores, powders, etc.Since they are ush mounted through a chute wall,nothing protrudes into the chute to interfere with orto obstruct material ow.
