The Challenge:

To characterize the performance of of push buttons on control panels for consistent operation and life cycle analysis:

 

  • What is the minimum force required to operate the button?
  • What is the maximum force a button can withstand without breaking?
  • Life cycle of a button operated at a specific force?
  • Life cycle of a button operated beyond the specified force?

 

How it works:

This solution allows the user to monitor forces applied on the push buttons and capture this data for analysis.

Results:

LoadVUE load cell software

Solution:

By integrating Miniature Load Cells with a linear actuator one can build a system that applies force cyclically.  Using our digital USB output option or using the 0-5V analog output action a user can capture data such as max/min force, number of cycles etc. and analyze data in Excel Matlab or other statistical analysis packages to optimize panel and button design.

Alternatively the user can use the DQ-1000A device to get a 0-5V Analog voltage output that can be directly input into a DAQ or PLC.

Parts Used:
1 iLoad Mini Digital Load Cell
1 DQ-1000U or DQ-1000A
LoadVUE (LV-1000) software

Total time to setup:
30 minutes

The Challenge:

Pedal force measurement for brakes, accelerator and clutch pedals are an important quality control step to ensure proper design, manufacture and product safety.

The recent problems faced by Toyota with unreliable braking or spurious acceleration is an illustration of this important testing need.  When a driver lifts his foot off the accelerator pedal and applies force on the brake, the car must slow down and come to a halt.  But if it doesnt how does none know that the driver actually did what he says he did?

One needs a pedal force sensor to measure the forces and an accelerometer to measure the acceleration and make sure the car and driver are doing what they should be!

Results:

LoadVUE Load Cell Software

Solution:

Our iPedal pedal force measurement solution easily attaches to a pedal (accelerator, brake or clutch) and provides an indication of the force being applied to it by a driver.

One can record the force data on a PC using our USB output and LoadVUE software.  An optional LED display or bargraph can be attached to the sensor to provide a visual readout of the force being applied to the driver.

If the test setup has a data acquisition system, then one can attach the load cell solution with 0-5V DC analog output to the DAQ directly.

Parts Used:
- IPEDAL-U-300*LV
- Includes iPedal 300 lb sensor with USB output and LoadVUE-1000 software
- Optional DS-300U LED Display

Time to Setup:
30 minutes

The Challenge:

To monitor one's center of gravity while swinging a golf club:

  • Is the golfer balanced?
  • With which center of gravity variation does the golfer hit the ball the farthest?
  • How does the alteration of one's center of gravity affect the distance and spin of the ball?

How it works:

This center of gravity monitoring system has the ability to track one's center of gravity pathway in order to enable golfers to optimize their golf swing to get maximum power and precision.

Parts Used:
  • iWeigh Pro Platform scale (4 100lb iload USB load cells & wired USB Hub)
  • LoadVUE CG software
Total time to setup
  • 15 minutes

The Challenge

Determine if press fit part is properly installed.

How it works

Users will use a hydraulic press equipped with a load cell to characterize proper installation of part which can be used in pass/fail criteria during manufacturing.

Solution

The load cell is attached to the press and displays force data on our RD-1000 Indicator and wirelessly feeds the force data into a PC using our DI-1000ZP interface. The software allows the user to log the data into an Excel friendly file for further analysis and characterization.

RSB2 Steel Button Load Cell(1)
Loadstar Sensor's RD-1000 digital scale indicator will interface with all strain-gauge load cells configurations. It provides all the basic scale operational features for the least cost.

RD-1000 Resistive Load Cell Display(1)
Loadstar's LoadVUE software permits you to display individual loads plus the sum of all loads, and log data on screen and to a file.

DI-1000ZP Wireless Load Cell Interface(1)
The new DI-1000Z can work with your existing resistive load cells for true digital, wireless connectivity.

LoadVUE™ Software (1)
Loadstar's LoadVUE software permits you to display individual loads plus the sum of all loads, and log data on screen and to a file.

The Challenge:

To automatically maintain the level of fuel between two set points

  • Is the level of fuel so low that it is affecting the productivity of your system?
  • Is the level of fuel at potentially dangerous levels?
  • At what level must the fuel be maintained in order to ensure your system maximum efficiency?

How it works:

This application of an iLoad Digital load cell coupled with a DS-3000 enables you to completely automate the stability of fuel levels in a tank. All the user has to do is set two range points for the fuel level, and the controller will ensure that the range is sustained. The setup eliminates the previous dependence on an external computer; however, the user can still use the optional USB uplink and LoadVUE software to log and plot data for further analysis.
