Force, deflection (bending) & crack opening measurement or experimental determination of the intensity of stress, KID and KIC-factor.With ultra high speed (8 channels at 2.5 MHz, one channel 20 MHz) ADC board for data acquisition.Including software package for research purposes.

Patented Laser Opto-Electronic Measuring System

The determination of the factor of intensity of distortion KIC or KID in dynamics requires the measurement of the crack opening displacement (COD) according to the applied force. While the measurement of these two parameters, force and particularly COD, poses no problems under normal test conditions, (ambient T° and slow distortion), it is not the case when the conditions become extreme, as in the case of a shock test with an impact pendulum where the use of a precision extensometer is not possible. In order to measure the distortion during a shock test, an optical method without contact is required, permitting measurement of distortion directly on the specimen during the rupture (test time about 300 ms) not only in the direction of application of the force (deflection) but also in the transversal sense (COD). A high-speed acquisition card (20 MHz, 8 channels) ensures a very precise sampling range.

Interface to PC to run w+b Impact Software for custom configuring, calculation, statistical evaluation, reporting and exporting of tests and results

Extendable with instrumentation package with strain gauged striker, optional deformation measurement, and ultra-high speed data acquisition system and data analysis software. The laser opto-electronic-measuring-system for deflection (bending) and crack opening measurement for the experimental determination of the intensity of stress, KID/KIC-factor can also be attached.

Designed for cutttingCharpy V and U notches and Izod V notches in 10 mm square alloy steel specimens.

Broaching Machines for Charpy V and U Notches

Intended for bench mounting, this robustly constructed machines cuts the notches by means of a specially designed multi-toothed broach which is drawn across the specimen by rotating the spooked hand wheel for Series BRM-M manual models or by pressing down button at the motorized Series BRM models. A Hand Vice for holding the specimen is built onto the machine body and the tooling includes the adjusters and stops necessary to ensure notch depth and position are correctly set. Attachments are available to facilitate most common specimens. Broaches are not included and must be ordered separately from the range available. An operational floor-to-floor time of 17 secs. can be expected, although if a continuous heavy workload is envisaged we would strongly recommend our Motorized Machine be considered.

With digital controller, air - cooled version. This refrigerated circulator is equipped with a bath opening for direct temperature controlling samples. The built-in CFC-free cooling circuit enables efficient heat removal.

Cooling Chambers for Impact Testing Samples

This unit is often used to replace expensive tap water cooling; robust design using high grade stainless steel and temperature resistant polymer with sealed bath cover; removable fan grid allows easy cleaning; bath is equipped with handles and drain opening; 2-speed power-pump to reduce turbulences in open baths, wear-free; integrated overload protection; user-resettable, adjustable over temperature cut-out and low liquid level protection; easy to operate by only 4 navigation keys; electronic PID control using a highly sensitive sensor for excellent temperature accuracy; RS 232C interface as standard; user-defined fixed temperatures with separate RTA for each temperature; display resolution selectable between 0.1 and 0.01 °C; limitation of the usable temperature range by high and low temperature setting; RTA = Real-Temperature-Adjustment.

This apparatus is meant for impact tests to be carried out at low temperatures.

Sample Pre-Conditioning Chambers

It is made from double chambered stainless steel with isolating cavity wall from foamed polyurethane 65 mm thick. Complete with double chambered cover and specimen rack.

Dry-Ice Maker: This device instantaneously produces the quantity of dry ice (solid CO2) required to reach temperatures down to -80 °C. The dry-ice maker must be connected to a liquid CO2 bottle with connecting pipe and it produces 100g dry-ice tablets, having Ø 75 mm and 25 mm thickness.
