＊【What is a two-wire system?】
A two-wire system is a signal transmission system in which power for the amplifier drive is taken from the current output signel,eliminating separate power supply wiring.





Features
 ■The two-wire system helps reduce costs associated with installation,wiring,and operations.
■The sensor body is composed of chamically-resistant plastic(PP).
■Both display resolution and internal resolution are 1mm
■The sensor qand the control unit are integrated into a compact,lighweight unit.

Applications and examples
■Liquid level management - e.g.,tank liquid levels　　　　　
■WAter level management in a sewer
■Water level measurement for lakes,ponds,or riversHAL420　使用例
