The Alliance Sensors Group S2A LVDT transmitter is a DIN-rail-mounted signal conditioner designed specifically for the power generation industry. It offers comprehensive diagnostics for sensor and wiring failure, real-time recalibration of the Full Scale and Zero outputs, and enhanced ground loop noise rejection.

The S2A utilizes front panel push buttons for easy calibration. It is engineered to work with the widest range of LVDT, RVDT, and inductive half-bridge LVRT sensors by providing four excitation frequencies that will operate most AC-LVDTs over a 50 to 5000mVrms range of sensor output. S2A modules offer 8 analog outputs and half-duplex RS-485 digital communications for remote setup and for saving a module's setup parameters to hot swap them with another module.

Applications include steam valve position feedback, governor and throttle valves, interceptor and stop valves, broiler feedwater pumps, and turbine control systems.
