A system for measuring change in length and/or deformation force on a sample in a longitudinal direction. The system is useful in thermomechanical analysis and/or dynamic-mechanical analysis, and comprises a pushrod extending in the longitudinal direction which exerts force on the sample, and a device measuring movement of the pushrod resulting from the change in length or deformation of the sample in the longitudinal direction. The measuring device includes: a pushrod base mounted on a stationary base with a guide so as to be movable in the longitudinal direction; a controllable drive for moving the pushrod; a detector measuring the force exerted by the pushrod on the sample; and a path sensor for measuring the movement of the pushrod.
A device for measuring a change in length of a sample force-loaded in a predetermined manner in a longitudinal direction, with a pushrod extending in the longitudinal direction, which exerts a predetermined force on the sample with an end of the pushrod during the measurement, and with a measuring device by which, during the measurement, the movement of the pushrod resulting from the change in length of the sample in the longitudinal direction is measured, wherein the measuring device comprises:
A device for measuring a deformation force on a sample deformed in a predetermined manner in a longitudinal direction with a pushrod extending in the longitudinal direction, which brings about the predetermined deformation of the sample with an end of the pushrod during the measurement, and with a measuring device by which, during the measurement, the deformation force accompanying the deformation of the sample in the longitudinal direction is measured, wherein the measuring device comprises:
A method for measuring a change in length of a sample which is force-loaded in a predetermined manner in a longitudinal direction wherein a predetermined force is exerted on the sample by a pushrod extending in the longitudinal direction and the movement of the pushrod resulting from the change in length of the sample in the longitudinal direction is measured by a path sensor, and wherein a drive of a pushrod base, to which the pushrod is fixed, takes place in the longitudinal direction relative to a stationary base, wherein the drive of the pushrod base takes place depending on the force exerted by the pushrod on the sample and detected by a force measuring device according to the predetermined force loading;
A method for measuring a deformation force on a sample deformed in a predetermined manner in a longitudinal direction wherein a predetermined deformation of the sample is brought about by a pushrod extending in the longitudinal direction and the deformation force accompanying the deformation of the sample in the longitudinal direction by a force measuring device is measured, and wherein a drive of a pushrod base, to which the pushrod is fixed, takes place in the longitudinal direction relative to a stationary base, wherein the drive of the pushrod base takes place depending on the movement brought about by the pushrod on the sample and detected by a path sensor according to the predetermined deformation;
