Electrical Gauges: Precision Monitoring

This category includes 17 electrical gauges, with display sizes ranging from 5-inch (117 mm) large-face gauges, 85 mm GPS speedometers, and 80 mm tachometers, up to a 52 mm (2-1/16") gauge series. The products are intended for OEM / ODM integration and OEM / aftermarket applications on heavy-duty trucks, commercial buses, industrial equipment, generator sets, and commercial marine vessels. The series is built on stepper motor and air core movements with PCB circuit design, paired with dedicated sensors for oil pressure, coolant temperature, fuel level, and air pressure, with applications covering engine RPM measurement, oil pressure monitoring, coolant and oil temperature monitoring, fuel level display, voltage and current monitoring, and brake air pressure monitoring.
