Four: Special Transducer for linear electrical ruler and angular position transducer


1. Non-isolation Internal Insert: (Sensor inserts type)


Non-isolation type, small size, it is easy to use. It can converter Position, angle signal to standard 4-20mA signal. High linearity, outgo 0.05F.S. Span and Zero can be adjustable by user through the potentiometer on the PCB. User can customize different suitable size and dimension product according to application environment. There are total five external points, connect to Electrical ruler and power supply.(size:PCB22x45mm)

Adjustment method:

Connect right of electrical ruler and power, load and measurement instrument. It is better to use high accuracy amperemeter, after operating ten minutes, adjust ZERO when the electrical ruler be in state of zero, make Iout=4mA,

Then make electrical ruler to rated value, adjust Span, make potentiometer to 20mA.Do these for two times can improve the accuracy grade..
