The Macro Sensors EAZY-CAL™ LVC-4500 is a standalone ratiometric signal conditioner, measuring the voltage difference divided by the sum (Va-Vb)/(Va+Vb), supporting AC LVDTs and RVDTs with a constant sum of secondary voltages, (Va+Vb).
Line Power Voltage Requirements (VDC)9 – 30
Output Type (mA)4 – 20
Output Type (VDC).5 – 4.5, 0 – 10, ±5
Transducer Type LVDT, LVRT Half Bridge, RVDT, Vdiff/Vsum
Operating Temperature Range-20 – 75 °C [ 0 – 165 °F ]
Ratiometric signal conditioning minimizes the thermal error of the position sensor. LVC-4500 provides several choices of voltage, current, and digital RS- 485 outputs. 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-4500 operates from a 9-30V DC power supply and is housed in a polyamide DIN rail-mounted enclosure. Calibration instructions, terminal functions, LVDT connection diagram and DIP switch functions are printed on the side panels for convenience.
Supports both constant sum (Va+Vb) and standard AC LVDTs, RVDTs
Significantly reduces LVDT/RVDT temperature sensitivity
