APPLICATIONS
- Acquires very low signals in disturbed areas needing galvanic isolated amplifiers.
- All types of measuring with universal acquisition card: temperature, distortion, pressure, force, acceleration, displacement…
DESCRIPTION
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.
