Delavan 320 Microwave Detector

Delavan’s model Microwave 320 is a single point electronic switch for ON/OFF action. It can be used for level control as well as detection of objects. This sensing principle can “see” through windows that are transparent to microwave energy. This makes the Microwave 320 especially useful for application on very aggressive as well as hot products as the sensors do not have to come into direct contact with the process material.

Typical Applications include
• Level control of liquids or solids in tanks, bins, hoppers or chutes.
• Severe Environments: Microwave/320 is unaffected by dust, smoke, fog or vibration.
• High Temperature Environments: The standard transmitter and receivers have an operating temperature of +60°C. Other units are available for higher temperatures.
• Abrasive Materials: Crushed coal, sand, ore. Rugged construction. No moving parts. Sensors do not protrude into flow stream.

Typical Uses include
• High Level Alarm or Control
• Plugged Chute Detection
• Truck and RR Car Position
• Flow/No Flow Sensing of Bulk Materials in Chutes on Conveyors

Benefits include
• Non-Contact Sensor does not contact subject when used as a position indicator control
• No Vessel Openings Sensors can see through most non-metallic vessels
• Non-Intrusive When the Microwave 320 is used for level control. Transmitter or receiver sensors do not protrude into vessel so bridging cannot occur
• Independent Time Delays Standard for smooth, chatter-free performance. Field adjustable
• Corrosion Resistant, Watertight Remote Enclosure Glass-reinforced polyester enclosure features captive hardware and stainless steel trim to endure the most corrosive environments
• Versatile Power Supply The standard unit accepts 120 Volts AC, 240 Volts AC or low voltage 24 DC input
• Fail-Safe A simple field selectable slide switch determines the high or low fail-safe mode
