Signal Conditioner Board provides LVDT and PC connectivity.

Press Release Summary:

Connecting directly to 2 standard AC LVDT transducers, CellMite® Model 4331-200 simultaneously generates serial output for PC connection and ±10 V analog output. It has on board storage for up to 3 calibrated LVDTs, each with integrated 6-point calibration that can be used to linearize LVDT outputs. Features include multidrop RS232/RS485 serial port, nonvolatile memory for parameter and calibration storage, automatic LVDT identification, and multi-point and mV/V calibration.

Original Press Release:

CellMite® M4331-200 Provides System Integrators with an Affordable & Complete LVDT-to-PC Solution

Electro Standards Laboratories (ESL), Cranston, RI, introduces the new Model 4331-200 CellMite® LVDT AC (Linear Variable Differential Transformer) Digital Signal Conditioner Board into their CellMite® product line. The CellMite ® LVDT connects directly to two standard AC LVDT transducers and simultaneously generates a serial output for connection to a PC and a ±10V analog output. This CellMite ® LVDT embedded conditioning board can be operated with a computer or simply setup by a computer and used as a stand-alone intelligent LVDT digital signal conditioner with analog output.

M4331-200 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 users and system integrators with an affordable and complete LVDT-to-PC solution.

The CellMite® LVDT also features nonvolatile memory for parameter and calibration storage along with Automatic LVDT identification with ESL's TEDS-Tag technology. Also incorporated into the unit are solid state relay switches, multi-point and mV/V calibration, and the ability to locate LVDT core null position. 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. CellView Software and Software Drivers are optional.
