The model USB-10-4 is a 4 channel LVDT signal conditioner that operates four LVDTs simultaneously, and converts the reading using 21 bit A to D converter. Four digital readings are displayed on the LCD screen. It can communicate with PC using USB port.

With USB interface there is no need for an external power supply. The maximum interface cable length is 5 meters max. When USB port is disconnected, use an unregulated 5÷12VDC adapter, 250mA max, external power supply. The display has a +/-9.9999 count resolution, with adjustable zero and scale.
