GAGE HEAD 4-20 mA Loop Powered

GI-750 Series

The NewTek GI Series Gage Head LVDTs are designed for a loop-powered 4-20 mA circuit, and have excellent linearity, high sensitivity and high resolution. They permit highly accurate readout and recording of an output signal directly without auxiliary signal conditioning electronics.? These GI Series spring-loaded LVDTs are designed for a wide range of position measurement and dimensional gaging applications and available in ranges of 0.10 inch (2.5mm) to 4 inches (100mm).
