7310 Dynamic Strain Gage Signal Conditioning Ampli er

Product catalog summary

Description: The 7310 Dynamic Strain Gage Signal Conditioning Amplifier by Advance Instrument Inc. is designed for precise conditioning of strain gage and transducer inputs in challenging environments. It features a differential signal amplifier with a high bandwidth of up to 800 kHz and gain accuracy of ±0.1%. The gain is fully adjustable from 1 to 9,999, and it includes a 4 digital LED display for various settings.

Features: The amplifier accepts various input types, including foil type strain gages and piezo resistive sensors. It offers programmable or selectable bridge constant-voltage excitation from 0 to 15V and includes automatic bridge balance with EEROM. The device is equipped with built-in shunt calibration circuits and optically isolated shunt calibration relays. It also features a programmable four-pole Bessel low-pass filter with selectable cutoff frequencies from 10 Hz to 100 kHz.

Applications: The 7310 is suitable for dynamic material testing, strain/stress analysis, and signal conditioning for various sensors, including load cells and semiconductor strain gages.

Specifications: The amplifier supports quarter, half, or full-bridge strain gages with built-in dummy gages. It provides fixed excitation settings and maintains stability with minimal noise and ripple. The bridge balance is automatic with a balance time of 8 seconds. Calibration is facilitated by internal shunt calibration resistors with high precision.

Amplifier Details: The gain is continuously variable with a direct reading accuracy of ±0.1%. The frequency response is DC to 800 kHz, and the device maintains stability with low nonlinearity and noise levels. The display includes a 4 digital LED for output voltage, and the filter characteristics are based on a low-pass active four-pole Butterworth standard.

Input & Output: The device uses a 15-pin input connector for sensor input and BNC connectors for amplifier output. It supports high input impedance and provides a digital voltmeter with 1mV resolution.

Operational Environment: The amplifier operates within a temperature range of -10°C to 60°C and can be stored between -20°C and 70°C. It is designed to function in humidity levels below 95% RH, non-condensing.

Power Requirement: The device requires an input of 110 or 220 VAC ± 10%, 50 or 60 Hz, 2 A.

Dimensions & Weight: The panel measures 1.3” x 5.2”, with an amplifier depth of 10.6” and a weight of 1.32 lbs.

Order Code & Accessories: The order code is 7310, and optional accessories include various channel enclosures with power supplies for the input connector.
