The most advanced and user friendly LVDT signal conditioner

The NTC-6000 Qwik-Cal  LVDT Signal Conditioner from NewTek Sensor Solutions provides an intuitive AC-LVDT setup process. Calibration is accomplished with front panel null indicators and pushbuttons to set Zero and Full Scale output positions. The NTC-6000 offers a choice of excitation frequencies, multiple analog output types, accepts a wide dynamic range of LVDT outputs, indicates LVDT connection failures, and incorporates a 2-wire RS-485 digital communications port. Along with color-coded plug-in screw terminal connectors and a 2 year warranty, these are just a few of the many advanced features that make NewTek Sensor Solutions NTC-6000 module an extremely versatile smart LVDT signal conditioner.


Operating Power:               +9 to +30 V DC (+24 V nominal), 90 mA max. at 24 V DC;

Excitation Voltage:            3.0 Vrms (nominal);    1.5 Vrms (nominal selectable)

Excitation Frequencies:     2.5 kHz, 5 kHz, 7.5 kHz, 10 kHz (selectable)

Auto-Master Syncing:      Master output couples up to fifteen slave units; if master

fails, new master is automatically generated for fail-safe excitation.

Master can be selected by the user for a repeated master

LVDT AC Output Range:  50 mVrms to 5000 mVrms at LVDT full scale position

Analog DC Outputs:       0 – 10V, 0 – 5 V, 0.5 – 4.5 V, ±5 V,

±10 V, 4 -20 mA sourcing

Loop Resistance:           <1kΩ  max. with 24 V DC supply

Output Non-Linearity:      0.1% of Full Span Output (FSO)

Noise and Ripple:               <1 mVrms (voltage output); 10 µArms (current loop


Fault Detection:                 Open LVDT winding, cable disconnected, loss of excitation, short

Failure Indication:             Flashing LED’s; analog output out of range; open-collector


Operating Temperature: -45°C to 85°C

Temperature coefficient: –<0.02% of FSO/°C (combined zero and span shift)

Zero/Full Scale Set:          Front panel push button or RS-485 command

Digital Interface:                RS-485 2-wire multi-drop network, 16 addresses
