Scaling 0-50 bar pressure 4-20ma sensor

I wonder if anybody could help me to monitor the excact pressure sensor value on program ! Already i know i can scale pt100 in this way:

:L    PW132

:SRW    3

:FDG                  // Convert to floating point.

:L    KG+2597656+00

:XG

:L    KG+2660000+03

:-G                   // Result in floating point.

:GFD

Hello runaway7,

do you have some more information for us?

• which PLC do you have (135, 155)
• which CPU do you have? (MLFB and exact name)
• which analog module do you use

That's very important at the S5 but there are some differences between the PLC's and the CPU's.

regards

Plc 135

Ai: 465-4ua11

Hello runaway7,

which measurement module do you use at the analog input card?

When you use current measurement, which value do you use (0...20 mA or 4..20 mA)?

Which module? (you should have 4 modules at your card)

• 6ES5 498-1AA11 – 50 mV/ 500 mV/Pt 100
• 6ES5 498-1AA21 – 1 V
• 6ES5 498-1AA31 – 10 V
• 6ES5 498-1AA41 – 20 mA
• 6ES5 498-1AA51 – 4..20 mA , 2-wire sensor
• 6ES5 498-1AA61 – 5 V
• 6ES5 498-1AA71 – 4..20 mA for 4 wire sensor

Which signal have your pressure sensor at the output? (current 0..20 mA, 4..20 mA, voltage 0..10 V...)

yes . i have pressure sensor signal  (current 4..20 mA)

 

 hello . i found it . for everybody who need it.

follow the enclosed file.

 also the number by KG is found by the formula in atttrachement.

be free to ask me every question
