| | | Changes in length (or volume) of sample caused by expansion, shrinkage or bending, moves the quartz probe and the ferrite core of the LVDT and causes an electrical signal in its coil. This electrical signal is amplified and recorded as a change in length The temperature of the sample is measured and recorded by a thermocouple | | Ease of use of the instrument is ensured by • the vertical mounting with selectable pushrod load of 0.1 to 200 g • changeable industrial furnaces for the temperature ranges of -150 to +500 °C and from ambient temperature to 1000 °C The temperature gradient over 50 mm of sample length is less than ±3 "C for the furnaces • measuring the sample temperature close to the sample and recording the change in length directly as a function of the temperature • easily exchangeable sample carriers and probes • mechanical adjustment of the measuring head, so that the sample length can be chosen between 1 urn and 50 mm • accessory for dynamic elasticity measurements | | |
