HVAC R22 refrigerant presure transducer conversations from presure value to it's corresponding temperature

Dear sir,

I'm using logo PLC with analog module AM2 for my Air-conditioning application, with following pressure transducer is connected to read R22 refrigerant actual presure

From this I can read read R22 refrigerant actual presure but simultaneously I want to read  it's pressure corresponding temperature from this presure temperature chart

Soo plz kindly help me with eg how to program for this

Thanks regards

Dear sir,

Plz find attached sensor detail for

Power supply... 24 VDC 

 controling signal... 0 TO 10 VDC

PRESURE... -1bar to 29 bar or -14.5 psi to 420.6 psi 

Thanks regards

You need a formula like t = a * p + b, where t = temperature, p = pressure, a and b = constants for example. If you don't have a formula, then type in the list of temperature and pressure in an Excel spreadsheet. With Excel you can try to create a formula in different ways. Depending on the formula it may be possible to solve it with a Logo controller, because the Logo only have basic arithmetic operations.

I don't think, that someone do this work completely for you, Scorp
