8431, Burster Load Cell, Miniature Precision

The force to be measured is introduced via the threaded pin in the directions of both tension and compression in the cylindrically shaped sensor body. Torsion and bending forces must be avoided. It is not absolutely necessary that the interior threaded parts are seated solidly on the end of the threads or floor surface of the sensor housing. It suffices to apply the forces via the threadings, but they have to be fixed by a nut or pinch screw.

Two stabilizing membranes in the interior of the sensor reduce the lateral force and torque to a minimum and guarantee high long-term stability of the electrical and mechanical values.

The network for temperature compensation or standardization is positioned on a covered board as a thickened part of the sensor‘s connecting cable.

The maximum static usage force is the greatest force in the direction of the measurement axis that the sensor can endure. The overload protection is not suitable for using the sensor often in the overload range nor for sudden loads. The sensors work independent of positioning and have an active side which effects the measuring element directly, whereas the passive side is solidly connected to the housing.

Application Examples:

• Detection of crack formation on solar cells
• Fewer rejects in wafer and cell production: hairline cracks in solar cells and wafers result in failure during subsequent processing. The type 8431 miniature Burster load cell detects these cracks even in very small force ranges, helping you to optimize your production yields.
• Innovative sensor design helps to achieve fast test cycles in cell/wafer fabrication.
• Built-in overload protection safeguards against application errors.
• Precision, aligned threaded pins apply force accurately yet are easy to adjust
• Accurate instrumentation amplifier, with user-definable scaling, maps the measurement range 0...1 N onto 0...10 VDC
