Hi all;

I have a bunch of K Type thermocouples (2 dozen) that I must convert to 4 to 20 ma.

Can anyone recommend an inexpensive product ?

DIN rail might be preferred ,,,,, but anything goes ....

TIA

try red lion they have an inexpensive converter

 

Try Klippon Slimpak http://www.weidmueller.de/uk/. There are plenty of
others but I have used these and would rate them as good as any.

 

Try GE Fanuc's line of signal conditioners called SensorPulse. They convert just about any signal to another signal.

 

Mark,
Inexpensive is a very relative term.
You may want to try the Wieland ATC series. We've had good success with them.

DEVAR Inc, has some 2 wire transmitters that fit into a Thermocouple Head Enclosure.

http://www.devarinc.com

Model 18-8111

K Range 0-200 DegF or 0 to 750 DegF +- .01%

Just had a brochure laying around.

 

Look at Action Q series.

Can I ask?? WHY to milliamp and not to a digital signal - ethernet or some fieldbus

 

Thanks to all for your suggestions.

To answer Rob, I need analog signals to feed my datalogger, which accepts either 0 to 5 VDC or 4 to 20 ma.

You can buy Philips make transmitters which are DIN rail mounted (of safety barrier size), available in market. There are several such products also.
