Labman has manufactured a number of systems which integrate off the shelf load cells to perform tensile or compressive tests. An off the shelf load cell is integrated with a Labman manufactured drive so that accurate force/displacement measurements can be made. Labman have also manufactured systems using load cells to measure friction on surfaces. The auto-force system uses a load cell to measure the force required to disassemble a valve assembly. Unlike standard off the shelf load testers the auto-force automates the process allowing the system to measure 10 valve assemblies without operator intervention. The system produces a force displacement curve for each valve assembly. All the data is stored and encrypted to comply with 21 CFR part 11.
