TFT Gauges: Advanced Instrumentation for Modern Vehicles
Progauges products introduce an advanced digital instrument cluster and TFT smart gauge series featuring 19 configurations, ranging from 1.44-inch single-function displays to 7-inch heavy-duty dashboards. Engineered for OEM/ODM integration, this series serves commercial trucks, buses, agricultural machinery, and electric vehicles. Supporting both analog signals and the SAE J1939 CAN bus gauge protocol, it communicates directly with the engine ECU to monitor oil pressure, coolant temperature, voltage, fuel levels, and battery SOC with exceptional precision and reliability.

Product Description
Overview
TG-0302 is a 3.4-inch TFT quad gauge with an 800 × 800 high-resolution display, consolidating four key vehicle parameters with indicator lights on a single screen: oil pressure (0–145 psi, red alert ≤ 10 psi), water temperature (100–250°F, red alert ≥ 212°F), voltmeter (12V system 8.0–16.0 V / 24V system 20.0–32.0 V), and fuel level (0–100%, red alert ≤ 10%). Two signal versions are offered: TG-0302-001 uses the SAE J1939 CAN Bus protocol to read directly from the engine ECU, while TG-0302 reads analog output from temperature, fuel level, and oil pressure sensors. Typical applications include heavy-duty trucks, buses, commercial vehicles, and construction equipment — for dashboard space consolidation and centralized information display. Available for OEM / ODM design development and aftermarket use, and supports integration on ICE (gasoline & diesel), Hybrid, and EV Vehicle platforms.
