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-0103 is a 1.44-inch TFT digital voltmeter for vehicle system voltage monitoring, with a 128 × 128 display. It supports both 12V systems (8.0–16.0 V, red alert ≤ 12.0 V) and 24V systems (20.0–32.0 V, red alert ≤ 24.0 V). Two signal versions are offered: TG-0103-001 uses the SAE J1939 CAN Bus protocol to read directly from the ECU, while TG-0103 measures and displays voltage directly from the electrical system. Typical applications include heavy-duty trucks, buses, passenger cars, agricultural machinery, construction equipment, forklifts, and generator sets — for electrical system and battery condition monitoring. Available for OEM / ODM design development and aftermarket use, and supports integration on ICE (gasoline & diesel), Hybrid, and EV Vehicle platforms.
