DATA SHEET Point Level Switch for Plugged Chute Detection Intelligent Electronics Save Time and Money • Automatically recognizes and ignores coatings to prevent false alarms. • Universal power supply automatically detects & adjusts to input power source • Standard & High Sensitivity Electronics, Field Selectable Application • Detects the presence of plugged material in chutes Economical Without Sacrifice • Retains superior performance. • Less maintenance than other technologies; no moving parts to hang up or wear out. Output • DPDT relay dry contacts at 5A, 120VAC. Remote Electronics • Unlike many technologies, electronics can be remote mounted to a convenient or safe location Eliminate Costly Plugged Chutes with Drexelbrook Sensors! Downtime is expensive and so is the clean up of process spills. Reliable detection of plugged chutes will keep your plant running smoothly and virtually eliminate spills that occur because of plugged conditions. Drexelbrook’s Flush-Mounted Sensors reliably detect presence or absence of material flowing through chutes. If process material stops flowing due to a plugged condition, the system will alarm, allowing further action to occur (alerting an operator, shutting down a conveyor belt, etc.). This permits the operator to prevent a problem before it happens. Rugged sensor design makes these systems ideal for coal (pulverizer and transfer chutes), wood chips, ores, powders, etc. Since they are flush mounted through a chute wall, nothing protrudes into the chute to interfere with or to obstruct material flow. Dust coating and/or wall build up will not affect the measurement. Drexelbrooks Cote-Shield circuitry “Sees” through any coating condition and eliminates false plugged chute signals. Curved and flat sensors are available. Chutes vary in size and shape. We have a sensor design to fit your chute. AMETEK’ DREXELBROOK www.Drexelbrook.com
