AUTEX pressure transducer 0–100 psi 1/8"-27 NPT, 316 stainless with sealed harness, 0.5–4.5V output

AUTEX 0–100 psi pressure transducer is a compact, 316 stainless steel sender that converts oil, fuel, air, or water pressure into a 0.5–4.5V linear signal for gauges and controllers.

This pressure sender is built for vehicles, industrial equipment, and test rigs that need a durable, plug-and-play pressure signal. The unit uses corrosion-resistant 316 stainless steel wetted parts and automotive-grade high-temperature plastic, and it ships with a water-sealed quick-disconnect mating connector and pigtail harness for straightforward installation. The transducer outputs a linear 0.5V at 0 psi to 4.5V at 100 psi when powered from a 5V DC supply, making it compatible with many aftermarket gauges, data loggers, and ECU inputs that accept a voltage-based pressure signal.

How precise and linear is the AUTEX sender across its 0–100 psi range?

The AUTEX pressure transmitter provides a linear voltage output from 0.5V to 4.5V over the full 0–100 psi span, which simplifies calibration and signal scaling. Linearity makes it predictable when converting voltage back to pressure in software or on mechanical-electrical gauges.

• Output mapping: 0 psi = 0.5V, 50 psi = 2.5V, 100 psi = 4.5V
• Designed for use with 5V DC power sources
• Stable voltage output suitable for ECU, gauge, and datalogger inputs

What fluids and environments can this sensor handle?

Wetted components are 316 stainless steel, which resists corrosion with a wide range of gases and liquids, including many oils, fuels, and coolant types. The housing and connector use automotive-grade, high-temperature plastics and meet common electromagnetic compatibility standards for noisy electrical environments.

• Compatible media: oils, fuels, air, water, and other liquids compatible with 316L stainless steel
• Electromagnetic compatibility: EN50081-1, EN50082-2, IEC61000-4-3
• High-temp plastic body for engine-bay durability

How do I install and wire the sender in my vehicle or equipment?

Installation is straightforward: thread the 1/8"-27 NPT pressure port into the pressure source and connect the included water-sealed quick-disconnect pigtail to the transmitter. Use the supplied wiring harness to route power (5V), ground, and signal to your gauge or controller, and verify signal scaling with a multimeter or gauge calibration procedure.

• Thread size: 1/8"-27 NPT standard pressure fitting
• Mating connector and pigtail harness included for sealed electrical connection
• Verify output with 5V supply: measure 0.5–4.5V across the output at 0–100 psi

What performance and build features help this sensor last under real-world use?

Construction emphasizes corrosion resistance and temperature tolerance with 316 stainless wetted parts and auto-grade high-temperature plastics. The sealed quick-disconnect and electromagnetic compatibility ratings reduce failure risk from moisture and electrical interference common in engine bays and industrial panels.

• 316 stainless steel wetted parts for corrosion resistance
• Water-sealed connector reduces moisture ingress risk
• EMC standards compliance for reliable operation near electrical noise

Who is this for: technicians, DIY mechanics, and integrators who need a reliable, voltage-output pressure sender for oil, fuel, air, or water systems. It suits aftermarket gauge installations, data-logging projects, test benches, and control systems that accept a 0.5–4.5V pressure input and require a rugged, corrosion-resistant sensor with a standard 1/8"-27 NPT fitting and a pre-wired connector for fast installation.
