I want to use an analog 4-20ma output sent to a loop powered digital process meter to display the temperature set point for an HVAC zone. This set point temp will only be allowed to range from about 50F to 85F so as to accommodate night set back temperatures and other non-occupied allowed indoor temperatures. Decimals are not needed so even a two digit meter would be fine although 3.5 is much more common and perfectly acceptable.
The lowest cost loop powered process meter I have found is from Omega for $50. See details here http://www.omega.com/ppt/pptsc.asp?ref=DP720041
I need about ten of these and was wondering if anyone knew of a lower cost process meter that would work for my situation. Color of numbers and display size (smaller is better) are not important. Mainly looking for something cheap of reasonable quality.
