Dynamic Strain Gage Signal Conditioning Amplifier

Dynamic Strain Gage Signal Conditioning Amplifier


7211 Signal Conditioning System is designed with and incorporates all the features necessary for dynamic precise conditioning of strain gage and transducer inputs in the most severe operating environments.

7211 Signal Conditioning and amplifier’s low-level signals to high-level outputs for multiple channels can be simultaneously and dynamically recorded and displayed on external devices.
