Length comparator

Length comparator

Make: LabTek

Model: SL-2060

Origin: India

Standards: EN 1367-4 | UNI 8147 | UNI 8148 | EN 12617-4 | EN 12808-4 | ASTM C151 | ASTM C490 | UNI 8520:22 | UNI 6687 | EN 680

General Properties:
This apparatus is used for a number of length measurements concerning mainly cement and mortar specimens with different lengths. For this reason the reference rods are not included and have to be ordered separately, consulting for an easy and quick choice, the specification table. Two column steel frame with adjustable top anvil to suit the specimen length. Fit with a digital gauge 12.5x0.001 mm.

  • Dimensions: 180x180x490 mm
  • Weight approx.: 10.5 kg

Including digital gauge 12.5x0.001 mm with serial output for PC connection.

The first method gives a higher precision of staff scale detection, but this method is time demanding and it is very difficult to capture a possible irregularity of the staff scale. In opposite to it, the second method can be easily automatized thanks to the availability of
digital levels remote control and an automatic reading. Next advantage of this system is the recent determination of reading precision of level (but without influence of compensator function ability). This process of calibration is associating staff calibration and currently
instrument testing and in literature it is called “system calibration”. During the system calibration process level height reading is changed through staff shifting and this change is compared with a length variance measured by the interferometer. It provides a height deviation as output, which can be processed by linear regression and provides staff scale.
Comparator for system calibration allows change of position toward the line of sight of the level, which is stably emplaced on a pillar. Comparators are mostly vertical, allowing measurement at the vertical staff, which is shifted in vertical direction. The second variety is
horizontal comparator (see the scheme below). The staff lies horizontally on a chariot. Vertical picture of a bar code is displayed in the mirror tilted by 45 deg to levels line of sight and to staff normal. The advantage of the first variant is that it allows installing level in
every distance. The disadvantage is constructional, a large vertical space is needed for an installation (twice length of the staff). In the case of horizontal comparator, real disadvantage is a limited distance of level and the staff given by mirror dimensions.
