Yes, you can use water with it. I believe the male NPT thread is 1/4" in diameter. However, you can always use a bushing to adapt it to whatever you're screwing it into (e.g., a nut or a bolt). use a 3/8" NPT female fitting to make it work).
It's a Chinese product.
It produces an analog voltage with a linear slope ranging from 0 to 1, depending on what you mean by "real time." 0 Psi to 4 Psi: 5 volts (or close to it). For the upper range of Psi per sensor (150 Psi for the one I bought), 5 volts (or close to it) is required (or close to it). I assume there is some minimal latency for the analog circuitry inside the sensor to convert mechanical energy to electrical energy, but you'll need to use an ADC (analog to digital converter) to process the data digitally, which has its own set of latencies depending on processing speed, bit resolution, and other factors. For my purposes, it's close enough to real time because I'm using an arduino board with a main loop time of less than 20 milliseconds with a bit resolution
Our item's specifications are as follows: br>Results: 5V–4. Output voltage is 5 volts linear. A pressure of 0 psi produces a value of zero. 2 x 5V, 100 psi outputs 4 outputs at 5 volts and 200 psi

I've included images of the sensor's actual text. For the sensors that were delivered to me, the correct pinout is: VDD (5V), Ground (Ground), and Output (ranging from 0 to 10V) are represented by the red, black, and green wires, respectively. 0 PSI to 4 PSI: 5V (150 PSI at 5 volts).
I used two of these, as well as a flow meter, to monitor the supply line and output pressure for an RO drinking water system. meter. They draw less than 3 mA each, which surprised me, and they seem to work fine for my needs at 3. My Arduino provides 3V power.
The connector is a little flimsy, but it works fine. I'd give it 5 stars if it weren't for the fact that I bought it to use on a lab scope and it has a response rate of 3ms, not the advertised 1ms or less.
As long as you calibrate it properly, this sensor will work. (At 150 PSI, the pressure is equal to 4. ) 5V). On my 2005 STI, I'm using an Aeromotive FPR for Fuel Pressure (using a TGV Harness to connect the data to the Cobb Accessport). The calibration is slightly off, about /-. In comparison to the liquid gauge I had previously connected, the pressure difference was 5 PSI. Otherwise, it's been running e85 for two months with no problems; I've had a few other cheap sensors die after a few weeks of use, but this one hasn't died yet.
On my digital gauges, I wanted to keep track of fuel and oil pressure. These were installed in a Porsche 944 with a VEMS (Versatile Engine Management System) replacing the factory Bosch DME (ECU). I can monitor the fuel and oil pressures with this unit installed, and it has worked flawlessly since then.
Pigtail snapped right away. This sensor is of excellent quality. The problem I had was that the pigtail clip broke almost immediately. The pigtail is made of bulky, low-quality plastic that is large and bulky. When I took it out of the package and tried to connect the two, the clip broke. Fortunately, they have a very tight fit, and the silicon seal provides some friction. For the sake of my application, I'm hoping it stays connected. br>br>It would be great if I could find a replacement pigtail, though this does not appear to be a common plug.
The calibration given isn't even close to being correct. The rest appears to be in good order. The proper calibration is 0. br>br> At 0 psi, the voltage is 5V, and at 4 psi, the voltage is 4. At 150 psi, 5V is used. Now it functions properly.
My standalone ECU's fuel pressure sensor had failed, so I replaced it. The exact same product as the manufacturer, but without the branding sticker and for a fraction of the price.
