Introduction: The dilatometer is composed of a domestic high-precision intelligent temperature controller, equipped with a horizontal or vertical double-body high-temperature furnace with a vacuum-formed full-fiber inlaid resistance wire. The instrument uses a microcomputer program temperature controller to automatically measure and control the temperature of the furnace according to the temperature program specified in the experiment, and a differential dilatometer made of a high-purity transparent fused silica tube with a high-precision digital displacement meter to record the elongation of the sample. This instrument is used to measure the average linear expansion coefficient (or linear expansion rate) of rigid materials between room temperature and 900°C. The instrument has the advantages of high temperature measurement and control accuracy, reliable work, convenient operation, high work efficiency (two samples at a time), etc. It is an instrument for carbon analysis in accordance with ISO14420 and GB3074-82 standards. Also applicable: YS/T63.4-2006 standard requirements. Technical Parameters: Power source: 220V Power rate: 2KW (horizontal) 1.5KW × 2 (vertical) α measuring range: >1.0×10-6 ℃-1 Temperature range: room temperature~900℃ temperature control: 1. Accuracy: soil 0.3% FS ± 1 word 2. Display mode: 4-digit double-row display 3. Input: Intelligent input, free choice of 11 types of thermocouples 4. Program setting: Programmable 9 segments, each segment is 9999 minutes, the program can be used for 99 large cycles 5. Control principle: Adopting 6 groups of conductive patented non-overshooting expert PID new algorithm, so that the adjustment parameters, power and anti-overshoot and undershoot of different temperature zones can be optimally matched. 6, Output: solid state relay time proportional output, the period is 0.5-120 seconds 7. Energy-saving servo start and power-on slow output can be set (1-120 seconds) 8. Ensure platform, power failure protection and digital lock function Displacement measurement: Measuring range: 2mm Resolution: 1μ Shielding gas flow: 0~10L/min Sample: Φ20×50mm
