Bag Filling Machine using Load Cell Input


Our customer manufactures machines for loading produce into bags at preset weights. A conveyor carries the produce to the bag. The conveyor speed controller slows the conveyor when the bag nears the required weight. The bag is hung from a load cell which feeds the weight to the Tiger 320 meter controller. When the bag is near the required weight, a setpoint in the meter slows the conveyor. When the bag reaches the required weight, the meter automatically compensates for produce inertia and determines when to stop the conveyor and close the conveyor feed gate. The display flashes between "BAGFUL" and "WEIGHT". The operator unclamps the bag, and the meter counts and totalizes the bag number from the bag clamp microswitch pulse. The operator fits a new bag and the clamp closes after a 1 second delay to stabalize the load cell.

Cut to Length Controller


Our customer operates an automatic cut-to-length guillotine. A Texmate 320 Series programmable meter controller has been installed and programmed to measure length from an encoder input. Setpoint 1 is programmed to operate at the required cut-off length. A clutch and a clamp operate to stop the metal feed motor.

Fruit Weighing Application


Our customer operates a fruit packhouse. His customers deliver their fruit in large bins for grading, packing and distribution. The full bins are loaded onto a conveyer and then transferred to a load cell weighing platform. The bin raises to a weigh position and then stops. After a 1 second delay (load cell to stabilize) the full bin is weighed. The bin then raises and tips the produce onto a second grading conveyer. The bin then returns to the load cell weigh position and stops. After a 1 second delay the empty bin is weighed.

Press Control Peak Overload Application


The Texmate 320 Series bargraph controller samples at 50 times/second for this application. The press operates at 60 strokes/minute. The load cell output is rapidly changing up and down during each stroke of the press. The operator requires the display to be held at peak value for as long as practical.

Watt / Hour Appliance Test Meter


Our customer requires a quality control test for watt/hour rating of electrical appliances. The test is carried out over 5 minutes. A Texmate DI-50E meter with a watt input module is installed. The meter is programmed to totalize the watt/hours when the start button is pressed. The meter totalizes the watts for 5 minutes and the watt/hour rating is held on the display.

Weigh and Ratio Batching Application


Our customer requires varying amounts of primary and secondary chemicals to be mixed by ratio. To improve mixing, accuracy and save time, the ratio calculation is automatically performed by a macro. A container is placed on a weighing platform and the platform is tared to 0. The primary product is poured into the container. The operator enters the required mix ratio and presses the start button.
