Intelligent Digital Signal Conditioner



The Electro Standards Laboratories’ Model 4325 Intelligent Digital Signal Conditioner connects directly to a standard strain gage transducer such as a load cell or extensometer, and generates a +/-10V analog output along with a serial digital output suitable for connection to a computer. The Model 4325 can compensate for transducer non-linearities using its integrated six-point calibration capability not found in standard signal conditioners. This compact unit is ideally suited for in-situ transducer conditioning and distributed process measurements. Its multidrop RS-232 serial port and simple command set allow for connection of multiple units in a serial network configuration. Features include nonvolatile memory for parameter and calibration storage, ability to select between two transducers, multi-point and mV/V calibration, remote sense excitation, and 24-bit internal resolution with 16-bit analog output. Field programmable for software updates.
