If the people who make the gauges won't tell you what the senders are, then they suck and you should call them out so the rest of us can avoid them...
Temperature sensors are just a thermistor in a package. There's 2 slightly different chemical compositions for NTC (negative temperature coefficient) sensors that I've encountered/know of - the original Bosch, and the one that Magneti Marelli uses. While these do result in slightly different temperature curves if you graph the calibration table, they're not wildly different - using the wrong table might make them read as much as 10C off at various points during warmup - and the difference tends to disappear at higher readings anyway, IIRC.
Ducati uses a Magneti Marreli short-reach temp sensor - also used in Fiats and certain years of Land Rover etc. Bosch short reach sensors include Porsche and VW ones.
VDO also make temperature sensors (the sender you show has what might be a VDO part number on it). I'd SWAG that they likely use the Bosch composition. If not, their tech support should be able to provide a calibration table. Or just test yours, compare to a Bosch/MM calibration table - and/or pick one from the VDO catalog in a more convenient package.
Gotta be easier than screwing with the thermostat/oil console...
As far as I know, pressure sensors are linear, variable resistance, typically against a 5V reference. So pick a sender with a convenient thread size.
