Alliance Sensors Group has expended its line of LVDT/RVDT signal conditioners to include the SC-100 DIN-rail mountable AC-LVDT Signal Conditioner module.
- Offers smart and fast LVDT setup with built-in null indication and simple front panel pushbuttons to set zero and full scale
- Engineered to work with wide range of AC-operated LVDTs, RVDTs, and inductive half-bridge position sensors
- Specifically designed to be compatible with both Marposs and Solartron analog pencil gaging probes
- Push button calibrated
- Power inputs from 15-30V DC
- Features four LVDT excitation frequencies of 2.5, 5.0, 7.5, and 10.0 KHz
- Six analog DC outputs 0-5, 0-10, +/-10, 0.5-4.5, 1-5, 0.5-9.5V DC
- Two current loop DC outputs of 4-20 mA or 0-20 mA (sourcing)
- RS-485 digital communications link with an available GUI
- Provides self-diagnostics for LVDT winding failures or cable disconnection
- Internal microprocessor eliminates need to calculate jumper settings for gain, range, etc.
- Full calibration is achieved by operator finding LVDT null, moving LVDT's core to one end of range and pressing zero button on front panel, then moving LVDT's core to the other end of specified range and pressing full scale button
- Features RS-485 digital communications port which permits a unit to be setup remotely using a computer or terminal, simplifying operations if the unit is already mounted on a DIN-rail in a cabinet
- If initial calibration data was saved in a computer via RS-485 port, another SC-100 can be “hot swapped” into an existing installation and then reloaded with original calibration data whereas ordinary AC-LVDT signal conditioners would require complete recalibration process
- Can be master/slaved to prevent beat frequency interaction between sensor signals for installations where there are multiple LVDT position sensors
- Auto-mastering feature causes another module to immediately become a new master for the slaves if an SC-100 master module were to fail
