Stainless steel pressure transducer with connector harness and 1/8-27 NPT thread

100 PSI Pressure Transducer Sensor with Connector Harness 1/8-27 NPT

SKU CH-YJ1E-PP4ZT

Measures 0 to 100 PSI with a 0.5 V to 4.5 V output on a 5 V supply, using a 316 stainless steel body and 1/8-27 NPT thread for oil, fuel, water or air

  • 5 V to 4.5 V linear output simplifies ECU integration
  • ±1.0 % full-scale accuracy delivers reliable pressure data
  • 316 stainless steel body with ceramic plate resists corrosion in oil, fuel, water and air
  • 1/8"-27 NPT thread enables direct fit to standard ports
  • Damping design absorbs pressure spikes for stable readings

Purpose & Fit

This 100 PSI pressure transducer suits automotive and industrial monitoring of oil, fuel, water or air systems. It installs directly into a 1/8-27 NPT port and connects through the supplied harness for data acquisition or gauge display. Not for buyers who need a higher pressure range or a different thread standard.

Signal, Power & Environment

The sensor runs on 5 V DC and delivers a linear 0.5 V to 4.5 V output across the 0-100 PSI span, with 0.5 V at zero pressure, 2.5 V at 50 PSI and 4.5 V at full scale. A 316 stainless steel body and ceramic pressure plate resist corrosion and instantaneous pressure spikes. Accuracy is rated at ±1.0 % full scale over the operating temperature range.

Deciding Specification

The 1/8-27 NPT thread size is the single specification that determines whether this transducer fits the intended port. Verify the port threading before purchase; no adapter is included.

Questions about this item

How do I wire the 1/8-27 NPT sensor to a 5V ECU and avoid the common ground-offset mistake?

Power the transducer with a clean 5V DC supply, connect its signal wire to the ECU input, and share a single ground point at the ECU; the sensor outputs 0.5V at 0 psi and 4.5V at 100 psi, so any extra ground resistance shifts the whole curve.

What part of the 316 stainless steel and ceramic assembly wears out first and when should I plan replacement?

The ceramic pressure plate and internal seals degrade over time; with clean oil, fuel, water or air they typically last several years, but contaminated fluid or pressure spikes above 100 psi shorten life, so inspect the signal at 50 psi (should read 2.5V) each season.

At what pressure does the ±1.0% FS error band become the limiting factor during a long pull?

The ±1.0% full-scale accuracy equals ±1 psi across the 0-100 psi range; at sustained high pressure near 100 psi this fixed error band is the first limit you hit before thermal drift or mechanical fatigue appears.
