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-0102 is a 1.44-inch TFT digital coolant temperature gauge for engine cooling system monitoring, with a 128 × 128 display, a 40°C to 120°C measurement range, and a red high-temperature alert at or above 100°C. Two signal versions are offered: TG-0102-001 uses the SAE J1939 CAN Bus protocol to read directly from the engine ECU, while TG-0102 reads analog output from a coolant temperature sensor. Typical applications include heavy-duty trucks, buses, passenger cars, agricultural machinery, construction equipment, forklifts, and generator sets — for engine thermal monitoring and overheat warning. Available for OEM / ODM design development and aftermarket use, and supports integration on ICE (gasoline & diesel), Hybrid, and EV Vehicle platforms.
Product Models
