Compliance with following International Standards:
IS : 14858 ‑ 2000 and IS 516
Introduction:
- The digital compression testing machine has been designed to meet the need for a simple, economic and reliable means to test concrete for its compressive strength
- The design expressive of simplicity, both of construction and operation, makes the machine easy to use and maintain.
- The digital machines are provided with a MANUAL pace rate controller, to enable maintain a constant rate of loading.
Salient Features of EIE ‑ Digital CTM Machine:
- 2 line Alphanumeric display with backlite, displaying ‑ Actual Load / Peak load, Rate of loading and Calculated load in N/mm² (as soon as sample fails)
- Four column high stiffness and high stability fully welded construction of the load frame.
- Direct reading of compressive strength in N/mm2 ‑No calculation required.
- Peak hold facility.
- Can manually control pace rate from 1 KN/Sec to 20 KN/sec.
- Pace rate indication in KN/Sec.
- Bar Graph indication to control the pace rate
- Built in memory for last 10 readings
- Automatic internal calibration(without Proving ring)
- Safety cut out for overload and electrical short circuit.
- Safety door on the front side for operator safety.
- Compact Pumping unit with manually variable rate of loading.
Scope of supply:
- High strength rigid structure (Loading Frame)
- Pumping unit (Oil source cabinet)
- Digital Load indicator
- High precision pressure transmitter
- Pair of compression platens
- High pressure hose pipe
Salient fetchers of data manager PC software (Optional At Extra Cost.)
- Two way communication i.e machine operates from computer and from the touch screen controller both (Stat, stop, save data and save graph)
- Results directly saved in excel file
- Graph also saved in excel file
- Capable to save customer name, other details of customer, ageing of cube moulds, identification mark of the cube mould, date and time of testing
- Capable to print direct report from the computer
- Capable to select different test parameters like pace rate, sample size and area from the computer (software)
Note :
- Use of 3 KVA three phase servo controlled stabilizer is essential to protect the machine against voltage fluctuations. Warranty voids in case of any damage due to power fluctuation.
