C.2 – CREEP TESTING MACHINES WITH LEVER SPRING MECHANISM

The LABORTECH company offers testing machines for long-term C.2 tests, where a constant load is exerted by a lever mechanism by means of a spring and a control force sensor. All modifications of CREEP test systems C.2 manufactured by us are designed so that the customer can fully rely on its function and accuracy under long-term constant loading (material flow) with force or stress, including elongation and at a constant homogeneous temperature in a high temperature furnace with reliable declaration of results. even after 100,000 hours of continuous loading.

Machine operation and machine control

LCD SIEMENS integrated into the machine frame, easy to touch, comfort of the machine at a very high level.
The machine is controlled by measuring and control electronics SIEMENS S7-1200.
Sampling frequency 1000Hz. Resolution level of analog signals ± 32,000 divisions.
PC connection – communication via Modbus TCP.
Připojení teplotního regulátoru SIEMENS TC-22 přes Modbus RTU.
Integrated UPC unit to cover electrical outages.

Axial coaxiality

Coaxiality set according to ASTM E1012.
Cross cutting edges contribute to axial alignment according to the requirements of ISO 204, ASTM E292, ASTM E139 and NADCAP.
Articulated clamping (using cutting edges) in two places.
System set by BENTROD unit – evaluation and optimization of concentric and edge alignment correction.

High temperature furnace

Special heating coils for long-term tests with separate thermocouples = field temperature homogeneity.
SIEMENS TC-22 temperature controller with precise control built into the machine frame.
Wide temperature range with tolerances better than ISO 204 and ASTM E139.
One, two or three thermocouples – depending on sample length, material and shape.

Control software

The integrated intuitive LOTETest test software ensures machine control (gradual release of weights).
Data collection and display of measured values from the force channel (if a force sensor is included), the elongation channel and the temperature on the sample as a function of time.
CREEPTest software serves as a higher form of data collection, database storage, generation of own methods, etc.

Safety

Based on their concept and construction, LABORTECH machines comply with all the above-mentioned EC directives on machinery and equipment.
Only state-of-the-art safety techniques and proven industrial components working in accordance with the following standards are used: EN ISO 12100: 2011, EN ISO 14120: 2017, EN ISO 60204-1 ed.3, EN ISO 13850: 2017, EN 61000-6-2 ed . 3, EN 614-1 + A1: 2009 etc.
