Automatic Vicat Needle ToniSET Compact

Automatic, computer-controlled Vicat needle instrument providing six measuring stations for the determination of the setting characteristics of binding materials, preferably of:

Cement according to EN 196, ASTM C 191 and AS/NZS 2350
Gypsum according to EN 13279 and ASTM C 472

 

Key benefits for the user:

✓ Fully automatic test procedure
✓ Automatic cleaning and drying of the needle resp. cone
✓ Data base storage of the results including corresponding test parameters
✓ Definition of different test parameters for each measuring station
✓ Quick measurement mode with switch off function for the automatic cleaning, e.g. for shotcrete
✓ Display of the setting process as chart and as single values
✓ Bidirectional data transmission with a host system (LIMS)
✓ High precision measurement of the penetration depth by incremental measuring system (resolution 0.05 mm)
✓ Low maintenance expenditure and high durability due to solid and high-quality design
✓ Connectivity option of an external thermostat for the exact tempering of the water

Description

Design

The ToniSET Compact is designed as a three-axle measuring system, that comes with 6 measuring stations. The three axes are driven by gear motors while optical switches are monitoring the respective final positions. The measuring stations are arranged in a circle inside a test basin that allows testing under water.

The Vicat moulds are installed in the basin by means of corresponding base plates.

The penetration depths of the needle are exactly measured by an incremental, contact-free measuring system. By an easy exchange of the drop rod the different drop weights can be realized.

The ToniSET Compact is equipped with an automatic cleaning and drying system for the Vicat needle.

A serial interface type RS232 enables the connection of the PC system that is needed to operate the instrument.

 

Operating Principle

The ToniSET Compact is operated by an external PC system (WINDOWS®) using the software VicatDB. Tests are prepared, controlled and evaluated by this software. After the onetime definition of the test parameters tests can be started directly after the input of an identification and the preparation of the specimen. Subsequently the instrument performs the test fully automatic and stores the measured values in a data base. During the test procedure all measured values as well as the actual setting progress can be read out at any time.

A selectable quick measurement mode allows shortest penetration sequences if required.

After the end of the test the evaluation can be done either automatically by the software or manually by the operator.
