100 PSI Pressure Transducer Sensor with Connector Harness, 1/8"NPT Thread Stainless Steel Pressure Transmitter for Oil Fuel Water Air

Very good 100 PSI sensor for my Arduino ESP32-based house water pressure monitor. Originally used for a monitor where Town Water is intermittent, I made two more for my own home to tell me when to change my whole-house water filters. I’m upping my rating after a few months in use. These sensors are pretty stable and consistent over time. Once I developed a good calibration regime, I found the 0-5VDC signal pretty linear with water pressure within my 0-75psi home water pressure application. And with the price of these units, it’s a 5-star product. I've now bought four of these sensors. One was bad and was quickly exchanged. I now have three in operation using a decent USB charger for the sensor's required 5VDC and to power the ESP32. Plumbing is a standard 1/8 inch NPT thread. I used blue thread tape cut narrow in half to seal the threads. The sensor appears very well machined in stainless steel. The removable wire harness is solid, easy to wire to, and easy to attach to the steel sensor. There are no instructions, but wiring is labeled and is simple: 5VDC supply, Ground, and analog output 0-5VDC. Works with Arduino, works for me. Nice product.

I have purchased 5 of these and 3 of them have failed after only a few hours of use. Other reviews warned me I wish I had thought twice about these cheap sensors. Don't by them! 1 star is too high a rating for these sensors!

I used this sensor for reading nitrous bottle pressure. Took a me a while to figure out why I kept losing nitrous and found out it’s because it was leaking through the sensor. This cheap sensor caused me a lot of money!!!!!

For the price and speed of delivery this is really good. Used for clutch pressure in my EFI system. I will try again but will buy a spare just in case.

First one sent lasted 10 minutes and failed. Upon inspection oil was leaking in the connector around the pins. Sent back and got a replacement. Replacement lasted 5 mins before the same problem. Very bad product.

I would like to say I did have an issue with my sensor and contacted the seller about it. The issue was that I expected the wiring to be Red - Power, Black - Ground, and Green - Data. Hooking it up like that made my sensor not work. I tested the pins of my harness with a multimeater and the black was Power, the red was ground, and green was still data. Follow the diagram of the sensor and not the picture of the plug for the pinout, and triple-check that the plug is wired correctly. I'm giving them 5 stars because their incredibly quick response and willingness to fix the issue with no hesitation! Not everything you buy in the world will work as expected. A company willing to fix the issue and help when things are not correct is way more to me than the inconvenience of replacing it or dealing with a company that makes you out to be the problem or denies the issue.

There are 2 main issues with this sensor. one is that its output is dependant on the source voltage. running it from 5 to 5.2v causes no output change but if source voltage drops to 4.9v the output drops along with it. Since the description doesnt give a working volgate above 5 volts I'm reluctant to try to push it over 5.2 so essentially you need a perfectly regulated 5v supply to properly run this thing. The 2nd issue is the one I recieved has a dead spot from 25 to 30psi where voltage just sits at 1.51v through that whole 5 psi range. Thankfully the range I'll be using it in is 50 to 60 psi where its very consistent and stable. Over multiple tests, both while slowly increasing or decreasing pressure, in the range of 45 to 65 psi I consistently get PSI x 0.0451 = volts as the most simplified and nearly perfect formula. As long as this thing doesnt break and fall apart like others Ive seen, it will work well for my application from what I see so far.

I used this sensor as a replacement for a snow 100psi boost reference for a methanol injection system and it works flawlessly. I sanded down the hex shape until it was round to fit into a coupler (without any damage to its functionality) and the sensor reads very accurately, providing good feedback to my controller to regulate methanol injection. Their support is also fantastic, with them sending me a new harness next-day for free after I accidentally broke the first during install.

Si problemas con el vendedor entrego a tiempo Pero el producto no funcionó.por más de 1 minutos comenzó a fugar líquido por el conector electrico Se compraron dos piezas y las 2 presentaron la misma falla de fuga el producto es de 100 psi y comenzó a fugar a a 45 psi
