AutoMeter Multi Purpose Pressure Sensor

AutoMeter Multi Purpose Pressure Sensors: The Right Signal for Every Gauge

When your AutoMeter gauge is only as accurate as the sensor feeding it data, choosing the correct pressure transducer matters as much as the gauge itself. AutoMeter's lineup of multi purpose pressure sensors is purpose-built to integrate seamlessly with their gauge ecosystem — from classic air-core short-sweep electric instruments to full-sweep digital stepper motor gauges — ensuring the signal reaching your dash is precise and consistent.

A Wide Range of PSI Coverage for Nearly Any Application

One of the most compelling aspects of AutoMeter's pressure sensor lineup is its breadth of pressure ranges. Digital Stepper Motor (Full-Sweep Electric) sensors span an impressive spectrum, including 0–15 PSI (part #2245), 0–30 PSI (#2239), 0–60 PSI (#2229), 0–100 PSI (#2246), and an extreme-duty 0–1,600 PSI (#2240) variant for high-pressure applications. For traditional Air-Core (Short-Sweep Electric) gauges, AutoMeter offers sensors covering 0–80 PSI (#2241) and 0–100 PSI (#2242), keeping older gauge setups fully supported. The Spek-Pro gauge line also has its own dedicated replacement sensors, such as the P13155, designed to maintain the precision of that performance-focused series.

Broad Fluid Compatibility in a Durable Package

These pressure transducers are designed to measure fluid pressure in relation to ambient pressure, and their fluid compatibility is notably wide. They are compatible with water/coolant, gasoline, ethanol, methanol, diesel, air, nitrous oxide, oil, and brake fluid — making a single sensor type appropriate for monitoring fuel systems, oil circuits, boost pressure, and more without needing specialized parts for every fluid type. The sensors are constructed from solid-state components and stainless steel for durability and vibration resistance, an important consideration in high-RPM or off-road environments where vibration can compromise sensitive electronics.

Designed to Fit AutoMeter's Gauge Ecosystem

Each sensor in the Digital Stepper Motor series features a built-in connector that mates to the Delphi Packard Metri-Pack 150 series connector, keeping wiring clean and reliable. The standard thread size is 1/8" NPT Male, a near-universal fitment in automotive and marine plumbing, and many sensors ship with a 1/4" NPT adapter bushing for additional installation flexibility. These sensors operate on a standard 12V system, consistent with the rest of AutoMeter's instrumentation lineup.

Matching the Right Sensor to Your Gauge

Because AutoMeter produces both air-core and stepper-motor gauge technologies, sensor selection is not one-size-fits-all. It is critical to match your sensor to the specific gauge type and pressure range you're monitoring. AutoMeter's detailed sensor specification documentation helps enthusiasts and professional installers identify the correct part number for their gauge series, minimizing the risk of mismatched signals or inaccurate readings. Whether you're monitoring turbo boost, fuel delivery pressure, or engine oil pressure, the right AutoMeter sensor ensures your gauge tells the full, accurate story.
