Non-contact apparatus for autogenous strain of cement paste and mortar in a corrugated PE-tube

Device name ：Non-contact apparatus for autogenous strain of cement paste and mortar in a corrugated PE-tube
Model：YC-BWS D
Origin：Beijing
Purpose：To measure automatically the autogenous strain of cement paste and mortar.

The product is developed according to ASTM C1698 and is superior to the standard requirement. The main components include three invar dilatometer benches, six eddy current sensors, one temperature and humidity sensor and some corrugated plastic tubes. The volume deformation of the sample can be transformed into linear deformation, which can avoid water loss in the test process. It is mainly used to automatically measure the autogenous strain of cement paste and mortar.
Maximum aggregate size：4.75mm

Features:

1、7 inch color touch screen, man-machine interface
2、Automatic recovery of power failure, test can be continued
3、On-line display of temperature and humidity and shrinkage data
4、Two-way measurement ensures free deformation of the tested specimen without restriction
5、The test data can be exported by U disk, and opened and processed by Excel.
