Innovate PSN-1 PowerSafe Nitrous Bottle Pressure / Wideband O2 Gauge Kit | 3893

The Innovate PSN-1 PowerSafe Gauge Kit is an advanced all-in-one monitoring and safety system designed for high-performance nitrous applications. Combining real-time wideband air/fuel ratio monitoring with precise nitrous bottle pressure measurement, this 52mm digital gauge delivers critical engine data while actively protecting your engine under extreme load conditions.

Built on Innovate’s DirectDigital™ wideband technology, the PSN-1 provides fast, accurate AFR feedback across a full performance range. Paired with a high-pressure 1500 PSI nitrous bottle sensor, it allows drivers to monitor nitrous system stability and fuel mixture in real time—two of the most important factors in preventing lean conditions and engine damage during nitrous operation.

What sets the PSN-1 apart is its integrated PowerSafe safety logic. This system can be configured to automatically trigger a safety response based on air/fuel ratio or nitrous bottle pressure readings. In a critical event, it can disable the nitrous solenoid via the included relay system, helping protect the engine from unsafe operating conditions without requiring constant driver intervention.

The compact 2-1/16” (52mm) gauge features an OLED display with fully customizable viewing modes, allowing users to monitor nitrous pressure, AFR, and shift light indicators in real time. Interchangeable bezels and faceplates make it easy to match the gauge to any interior or race-focused cockpit setup, while built-in serial connectivity allows integration with Innovate MTS data logging systems for advanced tuning and analysis.

Designed for serious racers and high-horsepower builds, the PSN-1 delivers both precision monitoring and active safety control in a single, streamlined solution.
