Alliance Sensors Group SC-200 LVDT Transmitter

The Alliance Sensors Group SC-200 LVDT transmitter is a DIN-rail-mounted signal conditioner for industrial measuring systems, testing laboratories, and factory automation. The SC-200 has a push button interface for fast and easy calibration of the Full Scale and Zero Outputs as well as color-coded screw terminal plugs for quick installation. It also features differential input to minimize ground-loop noise.

The SC-200 is designed to work with a very wide range of LVDT, RVDT, and inductive half-bridge (LVRT) sensors by providing four excitation frequencies that operate most AC-LVDTs over a 50 to 5000mVrms range of sensor output. SC-200 modules offer 8 analog outputs and a half-duplex RS-485 digital communications port for remote setup and for saving a module’s setup parameters to hot-swap them with another module.

Applications:
OEM Measurement Systems
Steel/Aluminum/Paper Mills
Test and Measurement
Factory Automation
