Product Introduction
GF series split LVDT displacement sensor (crack gauge), dedicated to online monitoring of crack depth, width,?
opening and closing degree of civil engineering projects such as bridges, tunnels, buildings, concrete pavements, etc.
The sensor is powered by 12-24VDC, fish-eye heads at both ends, and the electronic circuit is sealed?in a 304 stainless?
steel metal tube. It can be used in the open air or in a humid environment for a long time and work stably.?
The output signal is a standard 0-5V or 4-20MA that can be used by a computer or PLC. Output, or RS485 digital signal
