For controlling your hydraulic creep testing machines

Creep’R is a specialized control system for hydraulic creep testing machines. It enables the control of a battery of creep machines, with load and strain measurement, controlled loading and automatic reloading for long-duration tests, in compliance with standard NF EN 12390-17 (2019): loading in less than 30 sec., automatic control and reloading.

Creep’R control unit characteristics

• Control unit in mechanically welded sheet metal assembly, height 130 cm
• Logic module 24 logic inputs, 16 logic outputs
• Drive for controlling the hydraulic pump to control flow rate (up to 6L/min)
• Wired remote control, with open, close, preload, loading buttons
• Multi-piston hydraulic power unit (reliability, consistency and quietness), mounted on silent blocks, with external level and temperature indicator
• Ball-type sealed distributors for pressurizing the hydraulic bus
• Stainless steel reservoir – capacity 40 liters
• Pressure sensor 400 bar, accuracy 0.5%EM

Console characteristics

• 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

Software characteristics

• 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

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 liter
  • 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

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.
