Hi,
i need to find a digital/LCD/etc that takes three wire leads from a sensor.

hi, do u offer a display that works with this sensor?
got no response.

0.3m Wire Pressure Transducer or Sender Sensor for Oil,Fuel,Diesel,Gas,Air,Water

just want to install an oil pressure gauge:

Sensor outputs a V proportional to pressure. It has an equation
relationship between it and the units of pressure you want to display.

Normally this is done by using a micro to measure the V and compute
the resulting pressure and write that to a display.

In this case P = 7.5 x Vmeas - 3.75, P in psi.


Regards, Dana.

 

The most simple version, when there is no need for readings link to the pressure metrologically valid values, one may find attcarctive, no, damn attractive to add the three feet digital voltmeter, 3 digit or 4 digit or last year became available even 5 digit. Like this https://www.ebay.com/itm/New-Mini-T...hash=item48a24003dc:m:mIy9B6jAv7iPLqQSVvxkuFw
However when learning into mind that always for example 2 atm means 3,5 Volts is plain unsuitable, then some kind of factorizing circuit must be built in. Or resistive divider in the best case, until the weak opamp in the worst. Be scared, as smaller is K(u) of operational, as more it is prone for becoming wild. Everyone are scared from wild opamaps

 

thanks. need a waterproof display, forgot to say, but nbd

 

need a waterproof display

Check a marine supply catalog?

 

no clue whether this is waterproof... but here goes... this is a paired unit:

nice, thanks

Nope, it's a standard automotive sending unit and dash gauge. The sending unit connections can be doped with liquid tape sealant to waterproof them but not the gauge. Look for the same unit for marine use and you might find a completely waterproof unit.

 

Ohh it's for a Virago. I would just put an analog gauge on the pressurized line. No need to worry about power that way. I've never needed one... the idiot gauge is fine for me.

OK I got off my lazy butt, here...

It should at least be water-resistant on a motorcycle but didn't say so in the ad. I had the nylon hydraulic line one on a '61 Ford and it was always seeping oil behind the gauge connection, very very slowly but couldn't tighten it enough to stop it.

Actually there is:

• Water-resistant: able to resist the penetration of water to some degree but not entirely
• Water-repellent: not easily penetrated by water, especially as a result of being treated for such a purpose with a surface coating
• Waterproof: impervious to water

The last one, waterproof really lacks a good standard of measure. Waterproof to what depth, how many atmospheres?

The instrument panel on my motorcycle is likely more towards water resistant in that I can ride in heavy rain and all of my gauges work just fine. All you seem to want is anything which will work (display) when exposed to the elements like heavy rain or in marine us heavy spray. Just some trivia but it helps define what you want.
