APPLICATIONS
- Acquires very low signals in disturbed areas needing galvanic isolated amplifiers
- Measuring : distortion, pressure, force (gauge sensor)
DESCRIPTION
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.
