1.2k to 6k rheostat wanted, links?

[Ken Moore 23]

I have a situation where I need to convert 24VDC from a power supply to a 4-20mA signal. I'm currently using two points on a 0-5k pot with a 1.2k resistor in series. But my output is not linear. Was wondering if any forum members had a link to a supplier. thanks, Ken

Can't you use a small Voltage/Current Interface? (Potentiometer dividing the 24 VDC source to drive the interface to drive your 4-20 mA input). In this way you do not have to worry about linearity or potentiometer values.

I guess I wasn't clear. I need to hook up a 24VDC power supply to "something" and get a 24VDC 4-20mA output. Changable via a knob type adjustment

Is this what you are looking for? http://www.actionio.com/products/slimpak2/wv438.html Connect 24V power. Connect any pot in the 100 to 100K ohm range. Provides 4-20mA out.

Perfect. Thanks
