Product Line
Signal Conditioning Boards
The SMD Engineering team includes experienced electronics engineers who can design fully integrated sensor solutions to provide precise and accurate outputs. Electronics can be designed for a range of uses including filtering, averaging, temperature compensation and calibration.
Featured Model
Model E120
Current Loop Transmitter
The E120 accepts a millivolt bridge signal from any SMD load cell or pressure sensor and converts it to the industry-standard 4-20 mA current loop output — directly compatible with PLCs, SCADA systems, and process controllers. Loop-powered, compact PCB format, programmable span and zero for OEM integration.
