Controlling plant air into a pressurized vessel, approx. 5 liters... Looking for - 4-20ma in, 24vdc, 0-60psi out (or other ranges), PNP and/or analog monitor output, 1/4 or 3/8 NPT, fast, precise, calibrate-able. Want alternative to SMC's ITV2030 line, which is not true analog, and cannot be bench calibrated.

 

Your question is little bit too telegraph style:
1_Volume in gas means nothing: work massflow.
2_For fast response look for quartz type XTR maybe Avionics ?...

"Want alternative to SMC's ITV2030 line, which is not true analog, and cannot be bench calibrated." WHAT DOES IT MEANT ?

 

IMI Watson Smith via catalogue or local rep

 

SMC makes an I/P regulator, but it only turns air supply/exhaust valves on and off, making for a bumpy control scheme. Their Model No. is ITV2030. Additionaly, this unit cannot be zero'ed or spanned (no user adjustments are available). I want a replacement for this unit. Thanks.

 

Check out Fairchild Model T7950 I/P at http://www.fairchildproducts.com
It has output display, alarm indication and either alarm relay contacts and/or current feedback capability.

Can you provide a little more detail? I can't find 'IMI Watson Smith' on a web search. Thank you.

 

That was an excellent lead. Thanks, David.
