E300F4 amplifier conditioner can be used twofold:
- strain gauge sensor conditioner
- high precision amplifier for low level voltage
Galvanic isolation gives an excellent common mode rejection.
Gain, filter, sensor supply are set up manually (buttons at the front). Each amplifier has a 220VAC supply.
E325 is a very flexible programmable amplifier and easy to adapt for the user, whether material or software wise. E325 acquires all types of sensors. All functions are within the card, without any mechanical setting up : the user has direct access through connectors at the rear. Programming and tunning software (included for Windows) treats all configurations. VISA driver is also available....
Cracking condition of structures is an essential characteristic used in fracture mechanics and it has to be determined during tests.
The 'CRACK TRACKER' instrument has been specially designed for that purpose. It applies a non-destructive electrical method, related to the so-called potential method that relates the length of a crack to the potential difference V existing between two significant points placed on both sides of the crack, a current I following the specimen....
