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

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.

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

I bought two of these to measure the pressure difference across my water filters so I could easily know when to change them. I connected these to an ESP32 and was able to get a good pressure reading from them after installing them like any other plumbing fitting. However, they leaked out the electrical connector side, which corroded the pins completely, which broke off when I went to check why the pressure was no longer being read after a few weeks. Both of them did this. The gasket on the connector didn't seem to really seal anything - water just came out by the wire and ran along the wire. It was a good idea, but not a good product.

Used for my speed hut oil pressure gauge

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!
