CREEP’R Control System For Creep Testing Frames

Benefits

• Automates the control and monitoring of creep tests to limit human errors and guarantees continuous and usable data acquisition.
• Up to six frames can be connected to a single control unit and console assembly (See Specifications tab).
• Control unit in mechanically welded sheet metal assembly, height 130 cm.
• Logic module 24 logic inputs, 16 logic inputs.
• Control unit in mechanically welded sheet metal assembly.
• Stainless steel reservoir has a capacity of 40 litres.
• Loading in less than 30 sec.
• Automatic control and reloading.
• Pressure sensor 400 bar, accuracy 0.5%EM.
• Multi-piston hydraulic power unit (reliability, consistency and quietness), mounted on silent blocks, with external level and temperature indicator.
• Drive for controlling the hydraulic pump to control flow rate (up to 6L/min).
• Wired remote control, with open, close, preload, loading buttons.
• Touchscreen 10” – Resolution 1024×600 px (223x126mm).
• Ethernet port 10/100 for IMH console.
• CPU 32 bits – ARM clocked at 1 GHz.
• Data retrieval on USB key.
• Remote access for training, configuration and maintenance.
• Backup of tests and configuration, on USB key.
• Barcode reader (option) for reading the identification of the specimen to be tested.
• 7 user levels limiting access to certain parameters.
• Machine configuration parameters and test specimen definition.
• Preload control using the remote control, close to the machine.
• Loading up to nominal stress in less than 30s, in compliance with the standard.
• Once nominal stress has been reached, Creep’R regularly monitors the applied load and automatically readjusts if necessary.
• Load and strain measurements from each machine are automatically recorded.
• Remote access capability via internet.

Testing Frame

• Frame fully machined with 3 or 4 threaded columns to adapt to specimen size.
• Heat-treated steel platens, single-acting cylinder load 200 to 2 000 kN with low friction, stroke 50mm.
• Load sensor, accuracy 0.023%E.
• 2 multi-magnet magnetostrictive sensors, 4 measurement points per sensor, resolution 2μm, enable the measurement of strain on 2 stacked specimens, along 2 opposite generatrices, using bonded studs.

Industry Types: Energy & Environment, Research & Education.

Creep Frames

Up to 6 frames can be connected to a single control unit & console assembly via a measurement bus and a hydraulic bus.

Each machine is equipped with:

• A control block that can be fixed to the frame, or remote-mounted when used in a climatic chamber.
• A hydraulic accumulator to maintain the load, max pressure 350bar, capacity 1 litre.
• As an option, a second accumulator extends the machine’s operating range.
• A measurement conditioner for load sensor, resolution 500000 points, accuracy 0.003%EM.
• A CAN output, CANOpen protocol.
