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

The first one I received did not work. It output a voltage that floated around 100mV with or without any pressure. I hooked it up to a 5Vdc wall wart rated to 1A. At atmospheric pressure (not plumbed into a service line) the output was 112mV. It's supposed to be 500mV. Although I was not optimistic, but since I already bought the fittings required to connect it to a hose bib, I put domestic water pressure on it. As expected -- 100mV output. I can only assume the circuit inside (wheatstone bridge?) is just regulating the supply down to 100mV as opposed to actually measuring strain on a stainless diaphragm.I asked Amazon to send a replacement. If that works, there will be an edit below outlining what happened and I will adjust my rating accordingly. If there is nothing posted beyond this, I was 0-4-2.Edit: azn sent a replacement (next day!) and it works. If it works well in-situ, I'll come back and report. I raised my rating to reflect how well this one is working. I am running it on an esp8266 that has it's own voltage divider (100k/220k) onboard for 0-3.3v. I added another one with 47k/68k resistors to take 0-5v to 0-3v so I am running on the ADC ~100-1000 for 0-100 psig. I only need it to run for a year taking data, which I don't think is too much to ask. if it fails before that I will come back here and update. Otherwise, no news is good news.

Very accurate. Used as oil and fuel pressure senders for Holley Terminator system.

Product works awesome

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'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.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, Ground, and analog output 0-VDC. Works with Arduino, works for me. Nice product.

Good quality Functions with my digital readout on my ecu.

U get wht u order

Unfortunately, I received a customer returned sensor (LPN O 337862655) instead of a new one. I''ll hook it up to see if it works but there was probably a reason someone returned it the first time. Buyers should be aware.The sensor has worked for 12 hours reporting house water pressure so I updated the rating. It is hard to find details on how well any of these sensors work with water so I will update this review over time.

Needs adjusting for the application
