Review on 🛢️ Stainless Steel Pressure Transducer Sender Sensor - 1/8" NPT Thread (100 PSI) for Oil, Fuel, Air, and Water Deals on Black Friday by Bernard Larjin

This is a good industrial grade sensor. The photo shows a wire harness terminating in a JST connector - mine came with pigtails (with an automotive connector on the sensor as shown). The back of the sensor connector is not firmly attached to the connector, so do not pull on the back when removing the connector - pull on the retainer or you risk pulling on the wires. I have a 150psi version connected to an Arduino Nano clone. The sensor delivers a stable, linear output signal over the entire measuring range. The seller gave false information about the technical characteristics and possibilities. The sensor is actually more efficient than advertised. First of all, it is an ABSOLUTE PRESSURE sensor. At the same time, it delivers a linear output signal in a vacuum and shows no obvious hysteresis compared to the ambient pressure. Also, the specifications are ambiguous in terms of sensor response. Here are my observations (based on a test setup using a mechanical pressure gauge, compressed air and reading the raw sensor output). Note that my near-zero pressure reading was most likely affected by the mechanical gauge hysteresis: 0 psi. Vacuum on the sensor but didn't do any vacuum calibration measurements as my application doesn't require vacuum. PSIA) = 4.93 V. Linear scale factors (5 V supply, 10 bits): 1.047 kPa/bit; 214.3 kPa/V; 0.1518psi/bit; 31.09 psi/volt. I used Libre Office Calc (Excel) to plot the data and then drew a linear trend line using an equation to get the slope. Raw data: PSIG ADC (raw, 10bit/5Vref) 0 12710 20420 24830 31140 37750 44760 50870 58280 65190 719100 786 Hope this helps!
