FR series pneumatic LVDT displacement sensor

Product Introduction

Differential transformer displacement sensors (LVTD) can be widely used in aerospace, machinery, construction, textiles, 

railways, coal, metallurgy, plastics, chemicals, scientific research institutions and other industries in the national economy 

to measure elongation, vibration, High-precision position sensor such as object thickness and expansion

The DC LVDT sensor has excellent performance, 9-28V DC power supply, and the electronic circuit is sealed in a 304 stainless 

steel metal tube. It can work in harsh environments such as humidity and dust. The output signal is a standard 0-5V that can be

 used by a computer or PLC. 4-20MA output, or RS485 digital signal
