Overview
CellMite® 4338-200 LVDT AC Excitation Dual Channel
Intelligent Digital Signal Conditioner
The CellMite® Model 4338-200 Dual Channel LVDT digital signal conditioner connects directly to two standard AC LVDT (Linear Variable Differential Transformer) transducers and simultaneously generates a serial output for connection to a PC and a 10V analog output. The CellMite 4338-200 LVDT can be operated with a computer or simply setup by a computer and then used as a stand-alone intelligent LVDT digital signal conditioner with analog output.
The Model 4338-200 has on board storage for up to 3 calibrated LVDT's, 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.
Model 4338-200 features include non-volatile memory for parameter and calibration storage, the ability to select between 3 stored LVDT calibrations, and automatic LVDT indentification 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.
