CellMite LVDT AC Excitation Dual-Channel Digital Signal Conditioner Board
Electro Standards Laboratories, Cranston, RI, announces the Model 4331-200 CellMite LVDT Embedded Digital Signal Conditioner Board. This unit connects directly to two standard AC LVDT (Linear Variable Differential Transformer)
The Model 4331-200 CellMite LVDT has on-board storage for up to three calibrated LVDTs, each with integrated 6-point calibration that can be used to linearize the LVDT outputs. Its multidrop RS232/RS485 serial port and simple command set allow for connection of multiple units in a serial network configuration. This compact unit is ideally suited for in-situ transducer conditioning and distributed process measurements. It provides OEM user and system integrators with an affordable and complete LVDT-to-PC solution.
The Model 4331-200 features include nonvolatile memory for parameter and calibration storage, the ability to select between 3 stored LVDT calibrations, and automatic LVDT identification using TEDS-Tag technology. Solid state relay switches, multi-point and mV/V calibration, and the ability to locate LVDT core null position are incorporated into the unit. Internal generation of precision sine wave AC excitation voltages, remote sense excitation and 24-bit internal resolution with 16-bit analog output are also standard.
