High-Resolution 3-BAR 30-PSI 1/8 NPT threaded Boost sensor replacement for JRP GearX 52mm Gauges. Note this sensor is only compatible our 30-PSI model boost gauges which are listed in bold below.

Our 3-Bar 30-PSI 1/8 NPT Boost Sensor is a precision, manifold-mounted sensor designed for users who prefer a threaded installation over a hose barb connection. Built to the same high standards as our standard 3-Bar barb sensor, this variant offers a secure, professional fit for engines running up to 30 PSI of boost, while maintaining the same fast response and exceptional signal accuracy.

Our dedicated 3-Bar Boost Sensor has been purpose-built for turbo-diesel and low-pressure petrol applications, offering improved signal resolution, faster response, and rock-solid accuracy, the perfect match for our:

GearX 52mm Diesel 0-30 PSI Boost Gauges
GearX 52mm
 Petrol 30 PSI Boost Gauges

Like the barb version, it was developed to improve signal resolution for low-boost applications, taking full advantage of the 0–5 V output range to deliver smoother, more precise data than traditional 7-Bar sensors.

The 1/8 NPT thread allows the sensor to be screwed directly into a manifold or custom fitting — ideal for those wanting a cleaner install or who are running setups where high boost pressure can cause hoses to slip from barbs. While typically used in higher-boost diesel systems, many users prefer the NPT style for its durability and simplicity, even in moderate 30 PSI-and-under applications.

With its 3-Bar (0–30 PSI) absolute pressure range and linear 0–5 V output, this sensor offers excellent accuracy, repeatability, and resistance to electrical noise. It’s fully compatible with JRP GearX gauges, as well as dataloggers and standalone ECUs using a 0–5 V input signal.

Key Features:

  • 3-Bar (0–30 PSI) MAP/Boost sensor optimized for low-boost petrol & diesel applications
  • 1/8 NPT threaded fitting for direct manifold mounting — secure and leak-resistant
  • Full-range 0–5 V output for improved signal resolution and accuracy
  • Suitable for setups where barbed hose fittings are impractical or prone to blow-off
  • Compatible with JRP GearX 52 mm Diesel 0–30 & Petrol 30 PSI Boost Gauges
  • Compact, sealed automotive-grade housing for durability and reliability

At JRP, we’re always refining our components for improved performance and installation flexibility. The 3-Bar 1/8 NPT Boost Sensor gives users another option to achieve a professional-grade install with precise, reliable boost readings, whether you’re building a clean street setup or fine-tuning a performance diesel or petrol vehicle.
