[PSUBS-MAILIST] Digital Depth gauge with secondary display to passengers

[Alec Smyth via Personal_Submersibles]

Hi Lasse,

There are displays that can process the current input directly without any
need for signal processing on your part. See for instance the DPML or DPMO
series on the following page:

http://www.dwyer-inst.com/Product/ProcessControl/PanelMeters-Indicators

Within each series they have different models depending on type of input.
You would need to pick current input, such as DPML-401 for instance. Please
note I have not used these displays myself, but I came across them when
searching for components.


Best,

Alec
