NEMA 4 (IP67) high-pressure wash-down
NEMA 4X (IP67) wash-down/caustic solutions or solvents
Class I (solvent vapors), Division 1
Class I, Division 2
Class II (dust/powders), Division 1	Group:
Class II, Division 2	Group:

Electrical Specifications:

The Sonic 350 uses DC Servo motora controlled by a 110 VAC power source. The TSC 350 is provided with a 90 VDC motor. Other motor types and voltages are available for the TSC 350, as described below. The Checkweigher controller usess a source of 110 VAC, 50/60 Hz. 3 Amp power supply. Other voltages are available. Please select from the list below.

Controller Motor
Standard 110 VAC, 60 Hz
220 VAC Single Phase, 60 Hz.
220 VAC Single Phase, 50 Hz.

TSC 350 Motor
90 VDC (requires 110 VAC 3 Amp Source)
110 VAC 1 Phase with VFD drive
240/480 VAC 3 Phase with VFD drive
Other: VAC Ph, Hz.

Mechanical Specifications:

The TSC 350 Checkweigher can be provided with a wide range of conveyor configurations to meet your specific application. Depending upon maximum product length, conveyor speed, and production rate, weigh tables ranging from 2" to 18" in length are available. Standard overall length is 36", with other lengths up to 4'-0" are available.

Specify Overall Conveyor Length Required:

Minimum height for the Sonic 350 and TSC 350 is 28". The maximum height is 5'-0". Heights up to 4' are provided at no additional cost.

Specify Conveyor Belt Height:

If looking from top down onto the checkweigher, as in the diagram below, please answer the questions below:

Direction of Flow:	Left to Right	Right to Left
Direction of Reject:	Bottom to Top	Top to Bottom

Mechanical Options:

The Sonic-350 is a belt conveyor system, built with standard widths proportional to conveyor length. The TSC-350 is provided with two strands of conveyor chain. Additional strands of chain can be added to accommodate unstable or wide products. A variety of conveyor accessories are also available:

Metal Detector combined with Checkweigher
Product guide rails
Specify type of guide contact surface: SS with Delrin inserts Stainless Steel
Additional strand chain & chain guides for TSC 350
Transition Rollers. Bridges gap between Checkweigher conveyor and in feed and/or out feet conveyors for smooth transition of product onto and off of Checkweigher.
Caster mounts for movable systems. Food-grade compliant locking casters on stand allow system to be moved.
Wind Shield protects scale conveyor or weigh table from ambient air currents or passing equipment or personnel. Required on systems with very light products or high accuracy requirements
Timing screw in-feed for product spacing
Star wheel in-feed for product spacing
Acceleration conveyor to pull gap between products prior to entry onto checkweigher

Electrical & Software Options:

The Sonic-350 and TSC-350 Checkweighers offers a number of accessories and options to enhance your production line:

3-Zone Light Display (low-good-high)
5-Zone Light Display (low-low pass-good-high pass-high)
1� High LED Remote Digital Display
2� High LED Remote Digital Display
EWT1 Early Weight Terminate Photo-Eye. Allows for closer package spacing; higher throughput
Empty Package Detection. Senses empty containers or bags not sensed by scale
Closed-Loop Feed-Back Interface (pulse, serial, or count)
Model STPR Statistical printer package. Prints summary production & analysis reports on individual production runs
StatPak-PC Data Logging & Reporting Software. Collects weight data on all production, provides analysis and reporting on single or multiple production runs
Network Interface. Specify Type/Protocol; i.e., Ethernet, A-B, Profibus, etc.

Reject Options:

Thompson Scale offers a variety of reject devices to remove off-spec. packages from the production line. The standard checkweigher controller is capable of operating rejects separately for low, high, and metal contaminated products (when used with a metal detector interface)

Reject Devices used with the TSC 350 Checkweigher are intended for installation on the customer�s conveyor directly down-stream from the checkweigher. Optional reject conveyors can be provided, and will be quoted upon request. Sonic 350 Checkweighers typically include reject devices on the discharge conveyor that is part of the checkweigher system.

Air Blow Off		Stainless Steel nozzle ejects light weight products quickly and quietly from the production line to customer supplied bin or accumulation table.
Single Ram Reject		Delrin or Stainless Steel push plate ejects off-spec product at right angle to flow of the conveyor. Product ejected to customer supplied bin or accumulation table or conveyor
Dual Ram Reject		Same as above, but includes two rams, side-by-side, for separate reject of either low or high weights or weight and metal contaminated product.
Swing Arm Diverter		Rotating arm sits parallel to flow of conveyors. Reject extends arm to a preset angle to gently guide off-spec product from the main product line to customer supplied bin or accumulation device.
Drop Gate		Separate conveyor that resides directly after checkweigher. Hinged on the in-feed end, out-feed end of conveyor drops preset distance to discharge off-spec product to bin or accumulation area below.
Dual Lane Diverter		Rotary cylinder residing above conveyor line allows �good� product to continue on production line, but rotates to divert off-spec product to alternate conveyor line. Variety of reject accumulation conveyors available.
3-Zone Classifier		Using the same diverter described above, product is classified with low weight (or metal) diverted to one side of the production line, and high weight diverted to the other side. Includes up to 10 feet of accumulation conveyor with product guides and end stops.
5-Zone Classifier		Same as 3-zone classifier, but includes two additional zones. Custom configurations, lengths, etc. available.
Reject Horn		Alerts operator to rejects with either an audible or visual signal.
Reject Strobe		Duration of signal set through reject timers within the checkweigher controller.
