The Macro Sensors EAZY-CAL™ LVC-4000 is a standalone signal conditioner, supporting a wide range of AC LVDTs, RVDTs, and VR half-bridges, while providing several choices of voltage, current, and digital RS-485 outputs.
Line Power Voltage Requirements (VDC)9 – 30
Output Type (mA)4 – 20
Output Type (VDC).5 – 4.5, 0 – 10, 0 – 5, ±10, ±5
Transducer Type LVDT, LVRT Half Bridge, RVDT
Operating Temperature Range-20 – 75 °C [ 0 – 165 °F ]
Push-button calibration offers intuitive operation as compared to signal conditioners with span and offset trim pots. Fault conditions, such as a wire break on LVDT/RVDT connections, are indicated by blinking LEDs, fault condition error output, and Error Flag Open Collector signal (see manual for details). The LVC-4000 operates from a 9-30V DC power supply and is housed in a polyamide DIN railmounted enclosure. Calibration instructions, terminal functions, LVDT connection diagram and DIP switch functions are printed on the side panels for convenience. Synchronization to other signal conditioners is accomplished by a daisy chain connection to a synchronization bus. One unit will assume the Master function based on DIP switch priority setting. If a fault should occur, the next highest priority unit will take over as Master.
Push-button or RS-485 command auto-calibration
Analog voltage or current loop output
Digital RS-485 interface
Supports standard AC LVDTs, RVDTs, and VR half-bridge sensors\
