Adherence test are usually carried out using manual instruments, which makes it impossible to guarantee a constant rate of load increase.

The test is carried out manually the results are noticeable different depending on the rate and the regularity of the force applied by the operator on the handles.

To overcome this problem, the CEBTP has perfected the fully autonomous electronic adherence test instrument.

Movement is obtained using an electric geared motor with regulated speed to obtain uniform increased load. The force is read from a digital display.

- Maximum force: 1500 daN
- 12 V DC electric geared motor
- Maximum stroke of the standard traction screw : 30 mm
- Autonomous rechargeable 12 V battery
- LCD digital display
- Memorisation of maximum values obtained
- Zero adjustment
- Accuracy 1 to 2% of the value read between 100 daN and 1500 daN
- Rate of load increase : 25 daN/s
- Instrument weight : 5 kg
- Dimensions : length 260 x width 175 x height 280 mm
- Weight of auxiliary power supply case : 3,5 kg
- Dimensions : length 185 x width 120 x height 200 mm

OPTIONS :

- 220 V AC 12 V DC stabilised power supply
- Speed regulator selector (10 or 25 daN/s)

This 1500 daN instrument therefore replaces three others (250, 500 and 1500 daN) and a ratemeter; it provides a constant rate of load and is very autonomous.
