AUTEX 0-100 psi Pressure Transducer Sensor 1/8"-27 NPT — 316SS, 0.5–4.5V Output with Sealed Connector Harness

AUTEX 0–100psi pressure transducer is a stainless-steel 1/8"-27 NPT sender that converts oil, fuel, air, or water pressure into a 0.5–4.5V linear signal and includes a sealed connector harness for easy installation.

This compact AUTEX pressure transmitter is built from corrosion-resistant 316 stainless steel and automotive-grade high-temperature plastic to withstand oil, fuel, air and water environments. It delivers a stable, linear voltage output (0.5V at 0 psi, 2.5V at 50 psi, 4.5V at 100 psi) when powered by a 5VDC supply, making it suitable for data logging, engine monitoring, and control systems that accept analog voltage inputs. The package includes a water-sealed quick-disconnect mating connector and pigtail harness for straightforward wiring in harsh conditions.

How accurate and linear is the voltage output across the 0–100 psi range?

The AUTEX sender provides a linear voltage response from 0.5V to 4.5V across 0–100 psi, enabling predictable scaling by your ECU, gauge, or data logger. Linearity simplifies calibration and conversion to engineering units in software or instrumentation.

• Output: 0.5V at 0 psi, 2.5V at 50 psi, 4.5V at 100 psi
• Supply voltage: stable operation at 5VDC
• Linear transfer function for straightforward mapping to psi
• Good repeatability for monitoring and control applications

What materials and environmental compatibility does this pressure sender offer?

Critical wetted parts use 316 stainless steel (higher corrosion resistance than 304), and the housing uses high-temperature, auto-graded plastic to resist oil and fuel exposure. The sensor works with gases and liquids compatible with 316L stainless steel, making it suitable for many automotive and industrial fluids.

• 316 stainless steel body resists corrosion from fuels and coolant
• High-temperature rated plastic for long-term durability
• Suitable for oil, gasoline, air, water, and other compatible media
• Electromagnetic compatibility meets EN50081-1, EN50082-2, IEC61000-4-3

How do I install and wire the AUTEX pressure transmitter?

Installation is straightforward: thread the 1/8"-27 NPT sensor into a tapped port and connect the included water-sealed quick-disconnect harness. The mating connector and pigtail are supplied to reduce assembly time and improve protection against moisture and vibration.

• Thread size: 1/8"-27 NPT for common engine and hydraulic ports
• Included sealed connector and pigtail simplify wiring and moisture protection
• Designed for 5VDC supply; output is analog voltage (0.5–4.5V)
• Compact form factor fits tight engine bays and manifolds

Can this sensor handle EMI and harsh electrical environments?

The AUTEX sensor complies with common electromagnetic compatibility standards to reduce interference in noisy electrical systems. That makes it appropriate for automotive, marine, or industrial installations where radio-frequency or electromagnetic noise is present.

• Tested to EN50081-1 and EN50082-2 emissions/immunity standards
• Meets IEC61000-4-3 for radiated immunity
• Sealed connector helps protect wiring against shorts and corrosion

Who this is for: The AUTEX 0–100psi pressure transducer is aimed at technicians, DIY mechanics, and engineers who need a compact, corrosion-resistant sender with a predictable 0.5–4.5V analog output. It suits engine oil pressure monitoring, fuel system checks, compressed air pressure feedback, and water pressure sensing where a durable stainless-steel body, quick-connect wiring, and EMI resilience are required. If you need a robust, easy-to-install pressure sender that integrates with 5V systems and standard data acquisition or gauge inputs, this AUTEX unit is a practical choice.
