The AMETEK VTI EX1403A strain/voltage data acquisition instrument features 16 isolated channels and supports strain, bridge, resistance, and voltage measurements. Each channel is equipped with a 24-bit ADC, with a maximum sampling rate of 128 kS/s per channel. It supports quarter-bridge (120 Ω, 350 Ω, and user-defined 1 kΩ applications), half-bridge, and full-bridge measurements. The instrument provides built-in programmable excitation (constant voltage or constant current) and built-in shunt calibration, while also supporting calibration using an external shunt resistor. It supports TEDS or smart sensors and offers a variety of filter options. With high accuracy, high reliability, and excellent cost-effectiveness, the EX1403A is an ideal solution for complex structural testing applications worldwide.
