The DMD-460 Series bridge amplifiers are self contained, ac or dc powered signal conditioning modules for strain gages, load cells and bridge-type sensors. The DMD 465 contains a precision differential instrumentation amplifier with voltage output. The DMD 465WB is similar, but has a frequency response to 2 kHz. The DMD 466 is similar to the above units, but with a 4 to 20 mA output instead of a voltage output.

Are these units CE certified?? (DMD466 -120VAC etc)

Asked by: Philip
Thank you for contacting Omega with your question. Unfortunately, the DMD-460 series signal conditioners are not CE approved. For a model that is I would suggest the IN-UVI in line conditioner. Please feel free to contact us again if you have additional questions.

I'm only seeing manuals for 465 AC powered model. Where can I get a manual for 466DC?

Asked by: Imatrex
A manual for DMD466-DC is not currently available.

Can this amplifier be used with a bridge having 5kOhm resistors? Thank you very much, José

Asked by: José Figueroa
Hi, that unit is designed for standard 350 ohm bridges it cannot handle a 5000 ohm bridge, the output current would be too small for this unit to detect. We do not offer a unit that can handle a 5000 ohm bridge. Thanks for connecting with us.
