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

FUSCH 100 PSI Pressure Sensor Update 2025-09-15 Still very pleased, operating accurately to 0.10 PSI. See pic for current 37.2-psi on screen and gauge. Demand pressure changes about 15-times per day between 30psi and 60psi. FUSCH 100 PSI Pressure Sensor Update 2025-05-17 Three months in and the sensor is still working perfectly. It has been accurate to 1-Deciaml point with the gauge from 30.0 to 50.0. I have an IP camera on the gauge and Arduino display in the pump-house and they have not wavered at all. The live video is on the main IoT display on the house and the gauge is precisely following the sensor reports and controlling the pump on-off accurately. Love it so far. I bought another as a spare but doubt it will be used, but will report back here if needed. Original review: 2025-02-16 Using this with an IoT system monitoring our well water pump. The claimed output voltage rating is quite a way off, so I just set it to match the pressure gauge that I know is exact. The output is linear as I compared it at 20, 30, 40, 50, 60 and 70-PSI with the gauge, so I just added 7-PSI to the calculated result. The starting offset of 0.5vdc at 0-PSI was closer to 0.8vdc. It seems pretty stable and consistent over many daily 5-minute pump-cycles. I will report back if that changes. Previous sensors I have tried never mentioned "water" in their descriptions so they eventually rusted and became erratic. Hopefully this one is really rated for water. If there is no update above then it is still working well.

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

First thing when you tighten it it stops and only the sensor moves but threaded portion stops moving so you cannot tell if on tight or not! Also after installation the readings were all over the place fluctuated to over 100psi then down to 40 and so forth so basically useless and am past 30 day return window. I would try another brand

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.

Does not work. I have it hooked up to a Haltech 2500 on a fuel system with a manual gage reading 53psi. I can only get a readout of 100psi or 0psi, nothing in between.
