This system is used for calibrating thermometers. A standardised and precise movement is required for this. he deviation must not exceed 0.2 millimetres. To achieve high productivity, the linear guides should also be maintenance-free. The best results were achieved using two drylin® T plain bearing guides arranged in parallel. The linear guides are lubricant- and maintenance-free and allow jolt-free, precise movement of the calibrating system. In addition, a drylin® TWBM manual clamp with brass friction blocks was installed.
