A Signal Conditioner that Simplifies LVDT Setup

Alliance Sensors Group introduces the S1A AC-LVDT signal conditioner with smart and fast LVDT setup, built-in null indication and simple front panel pushbuttons to set zero and full scale. The company says that the conditioner further offers:
- Engineered to work with the widest range of AC-LVDTs, RVDTs and inductive half-bridge sensors including 3-wire GE LVRTs and gas turbine LVDTs, the S1A DIN rail module supports LVDT operation and indicates most common failures.
- The S1A offers a choice of four excitation frequencies, eight analog DC outputs (six DC voltage and two current loop outputs) and RS-485 digital communications.
- Ideal applications for the module include turbine control systems, steam valve position feedback, and other types of redundant control systems that use LVDT position sensors.
- The internal microprocessor eliminates the need to calculate jumper connections for gain, range, etc.
- In the event of a failure, a new S1A DIN rail module can be “hot swapped” into an existing installation, with initial calibration data saved then reloaded via RS-485 port.
- For installations where there are multiple position sensors, the S1As can be master/slaved to prevent cross talk between sensor signals.
