MODEL 220 B
This unit is a capacitance type point level sensor that detects the presence or
absence of material directly contacting the 3” sensor disk.
High temp FG sensor head with operating temps to 500° F [model 420 B].
Ceramic sensor head with operating temperatures to 900° F model 520 B].
Flush mount or adjustable depth sensor head.
Mounting flanges to fit bolt patterns of existing sensors.
Normal installation requires mounting the head flush with the inside of the cyclone
wall, producing a non-intrusive sensor.
A special adjustment feature allows the sensor head to be projected internally up
to 6” in cases where a probe type sensor is required.
ONLINE MOISTURE INDEX SENSOR – MODEL # 220 MIS
Feed Mill – Pelleting Process / Typical Locations: On mash stream after conditioner to give mash moisture entering pellet mill. On mash stream before conditioner to give starting moisture reading. On cooler discharge stream to give finished pellet moisture & shrink information.
DDG – cyclone discharge / drag conveyor to load-out area. Sensor is mounted in bottom of drag conveyor carrying Dried Distillers Grain from blow-line to storage / load-out area. Output signal gives final moisture of
product at load-out storage area.
DDG – dryer discharge. Sensor is mounted at discharge stream or in recycle chute of dryer. Sensor
Output is used to regulate key parameters for optimum dryer performance.
Whole Corn – drag conveyor from storage bins to feed mill. Sensor is mounted in side of drag conveyor bringing material to hammer mill and pellitizer. Sensor output gives operator accurate moisture information for segregation and blending.
Corn Gluten – discharge from dryer. Sensor is mounted in dryer discharge chute or in bottom of discharge
screw conveyor. Moisture output helps to control dryer parameters.
Soy meal – chute discharge from dryer. Sensor continuously monitors moisture level of meal exiting the dryer. The signal is displayed on the control screen allowing the operator to adjust dryer speed and temperature for optimal meal quality and fuel consumption.
Soybean – truck dump receiving hoppers. As a load of beans enters the hopper, the sensor gives an instant reading to determine if that load falls within an acceptable moisture range. If the bean moisture is above an acceptable level, that load is conveyed to a different
storage bin for additional drying.
Foundry sand – sand conveyor feed to muller. Sensor is mounted in conveyor stream to help regulate amount of
water needed for proper molding sand consistency.
“Since installation of the A2D2 system 2 months ago, we have recouped all investment costs through both fuel savings from our dryer and (more importantly) the ability to run our system much closer to the moisture targets specified by our customers.”
LEVEL SENSOR – Model 510
PRECIPITATOR HOPPER – FLY ASH APPLICATION
900 F. MAXIMUM TEMPERATURE
This unit is a flush mount capacitance type point level sensor that detects the
presence or absence of material directly contacting the 2 ½” sensor disk.
Robust construction includes a ceramic sensor disk that allows continuous
operation up to 900 F. The sensor can be manufactured with a remote
electronics package. This allows the electrical housing to be located on the
floor of the hopper area, making it easy for initial electrical hook-up as well as
ongoing monitoring of the sensor’s performance.
This system has been used as an alternative to nuclear level sensors.
Normal installation requires mounting the sensor head flush with the inside of
the bin or hopper wall, producing a non-intrusive level control system. A
special adjustment feature allows the sensor head to be projected internally up
to 6 inches in cases where a non-flush installation is necessary.
