UTS multichannel strain-gage amplifier

UTS AmplifiersUTS series strain gage amplifiers feature high gain, wide frequency range, low noise and current-feedback gage excitation mode for extension wire resistance compensation.

The amplifiers are intended to provide a signal conditioning interface for data acquisition systems when conducting bench- and flight-tests of aircraft engines. Other typical applications include modal analysis, fatigue and vibration testing.

Special features: gage circuit integrity indication; automatic disconnection of the failed circuits; built-in generator for self-diagnostics. Large LED display continuously monitors the output and simplifies setup and calibration procedures.
