Strain Sensors

M240 ICP

Strain Sensors are ideal for industrialapplications that require the measurement of repetitive strain curves such as monitoring forces experienced during manufacturing, assembly, on-line processes, quality assurance, or end-of-line product testing.In typical applications, upper and lower control limitsare set to follow a desired force curve for the process, and if the actual force curve deviates from the control limits, the process is shut down. This prevents acceptance of non-conforming parts as finished goods. Mounted on a C-frame press or actuator with a single screw simplifies installation and keeps the sensor out of the machine tooling. Optional JM240 ground isolated version available forresistance spot welding machines. For research and development applications or when a mounting screw is not permissible, the Model 740B02 allows for adhesive mounting.
