NTC-6000-DS LVDT signal conditioner

Product Description

The model NTC-6000-DS 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). Ratiometric signal conditioning minimizes the thermal error of the position sensor.

NTC-6000-DS 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. 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. With the use of the RS-485 port, a host computer is able to retrieve measurement data, receive operational status, perform remote calibration, and perform hot swap re-configuration where the calibration settings can be digitally uploaded.
