AUTEX 0–100 psi Pressure Transducer Sensor — 1/8"-27 NPT 316 Stainless Steel Sender with Sealed Connector Harness

AUTEX 0–100 psi pressure transducer is a compact, 316 stainless steel sender that converts oil, fuel, air or water pressure into a linear 0.5–4.5V electrical signal with an included sealed connector harness.

This pressure transmitter is built for vehicles and equipment needing reliable pressure feedback where corrosion resistance and a sealed electrical connection matter. The sensor uses 316 stainless steel wetted parts and an automotive-grade plastic housing to withstand common fluids. It outputs a predictable voltage proportional to pressure (0 psi = 0.5V; 50 psi = 2.5V; 100 psi = 4.5V) and ships with a water-sealed quick-disconnect mating connector and pigtail for faster installation.

How accurate and predictable is the AUTEX pressure sender?

The device provides a linear voltage output across the 0–100 psi range, designed so you can map voltage to pressure with simple scaling. It runs from a 5VDC supply and delivers repeatable steps at common reference points (0, 50, 100 psi).

• Linear output: 0.5V at 0 psi; 2.5V at 50 psi; 4.5V at 100 psi.
• Designed for use with 5VDC systems for consistent readings.
• Suitable for analog-to-digital conversion or gauge input.

What fluids and environments can this sensor handle?

All wetted components are 316L stainless steel, chosen for broad chemical compatibility and improved corrosion resistance over 304 stainless. The sensor is compatible with gases and liquids that are safe for 316L stainless steel, including oil, fuel, air and water under normal conditions.

• Wetted material: 316L stainless steel for enhanced corrosion resistance.
• Fluid compatibility: common automotive and industrial oils, fuels, air and water.
• Electrical components use high-temperature, auto-graded plastic for thermal stability.

How simple is installation and electrical hookup?

The sensor arrives with a water-sealed quick-disconnect connector and a pigtail harness, so you can make a sealed connection without sourcing separate connectors. The 1/8"-27 NPT male pressure port fits common adapter blocks or ports found on engines and equipment.

• Thread: 1/8"-27 NPT male pressure connection for standard fittings.
• Includes mating connector and wire harness (pigtail) for sealed wiring.
• Wiring: outputs 0.5–4.5V proportional to pressure; requires 5VDC supply.

What electrical and EMC characteristics should I expect?

The transmitter gives a stable linear voltage output and meets common electromagnetic compatibility standards to reduce interference in automotive and industrial installations. Its output range allows straightforward interfacing with microcontrollers, data loggers, or analog gauges.

• Output range: 0.5V–4.5V linear voltage proportional to pressure.
• EMC compatibility: conforms to EN50081-1, EN50082-2 and IEC61000-4-3 test standards.
• Designed to work reliably in electrically noisy environments when properly installed.

Who is this for: technicians, OEMs and makers who need a compact, corrosion-resistant pressure sender for oil, fuel, air or water systems. It's suitable for automotive dashboards, marine installations, small engines and industrial equipment where a sealed electrical connection, 316 stainless wetted parts, and a predictable voltage output are important. If you need a robust 0–100 psi analog sender that integrates easily into 5V systems and includes a connector harness, this AUTEX transmitter is built for that purpose.
